    The distribution of lectin bindings in the testis of babirusa, Babyrousa babyrussa (Suidae) was studied histochemically using 10 biotinylated lectins, Peanut agglutinin (PNA), Ricinus communis agglutinin (RCA I), Dolichos biflorus agglutinin (DBA), Vicia villosa agglutinin (VVA), Soybean agglutinin (SBA), Wheat germ agglutinin (WGA), Lens culinaris agglutinin (LCA), Pisum sativum agglutinin (PSA), Concanavalin A(Con A) and Ulex europaeus agglutinin (UEA I). Nine of 10 lectins showed a variety of staining patterns in the seminiferous epithelium and interstitial cells. The acrosome of Golgi-, cap- and acrosome-phase spermatids displayed various PNA, RCA I, VVA, SBA and WGA bindings, indicating the presence of glycoconjugates with D-galactose, N-acetyl-D-galactosamine and N-acetyl-D-glucosamine sugar residues respectively. No affinity was detected in the acrosome of late spermatids. LCA, PSA and Con A which have affinity for D-mannose and D-glucose sugar residues were positive in the cytoplasm of spermatids and spermatocytes. DBA was positive only in spermatogonia. In addition to DBA, positive binding in spermatogonia was found for VVA, WGA and Con A, suggesting the distribution of glycoconjugates with N-acetyl-D-galactosamine, N-acetyl-D-glucosamine, D-mannose and D-glucose sugar residues. Sertoli cells were stained intensely with RCA I, WGA and Con A. In Leydig cells, RCA I and Con A were strongly positive, while WGA, LCA and PSA reactions were weak to moderate. The present findings showed that the distribution pattern of lectin binding in the testis of babirusa is somewhat different from that of pig or other mammals reported previously.

  2. Fulltext A low-cost solution for documenting distribution and abundance of endangered marine fauna and impacts from fisheries

    Fisheries bycatch is a widespread and serious issue that leads to declines of many important and threatened marine species. However, documenting the distribution, abundance, population trends and threats to sparse populations of marine species is often beyond the capacity of developing countries because such work is complex, time consuming and often extremely expensive. We have developed a flexible tool to document spatial distribution and population trends for dugongs and other marine species in the form of an interview questionnaire supported by a structured data upload sheet and a comprehensive project manual. Recognising the effort invested in getting interviewers to remote locations, the questionnaire is comprehensive, but low cost. The questionnaire has already been deployed in 18 countries across the Indo-Pacific region. Project teams spent an average of USD 5,000 per country and obtained large data sets on dugong distribution, trends, catch and bycatch, and threat overlaps. Findings indicated that >50% of respondents had never seen dugongs and that 20% had seen a single dugong in their lifetimes despite living and fishing in areas of known or suspected dugong habitat, suggesting that dugongs occurred in low numbers. Only 3% of respondents had seen mother and calf pairs, indicative of low reproductive output. Dugong hunting was still common in several countries. Gillnets and hook and line were the most common fishing gears, with the greatest mortality caused by gillnets. The questionnaire has also been used to study manatees in the Caribbean, coastal cetaceans along the eastern Gulf of Thailand and western Peninsular Malaysia, and river dolphins in Peru. This questionnaire is a powerful tool for studying distribution and relative abundance for marine species and fishery pressures, and determining potential conservation hotspot areas. We provide the questionnaire and supporting documents for open-access use by the scientific and conservation communities.

    PMID: 32813222 DOI: 10.1007/s11230-020-09929-1
    A new species of Acroeimeria Paperna & Landsberg, 1989 is described from the spotted house gecko, Gekko monarchus (Schlegel) from Peninsular Malaysia. Oöcysts of Acroeimeria grismeri n. sp. are spheroidal to subspheroidal with a smooth bi-layered wall, measure on average 18.4 × 17.3 µm, and have a length/width (L/W) ratio of 1.1; a micropyle and an oöcyst residuum are absent but variable polar granule(s) are present, commonly in Brownian movement. Sporocysts are ellipsoidal and measure on average 8.6 × 6.7 µm, L/W 1.3; Stieda, sub-Stieda and para-Stieda bodies are absent. The sporocyst residuum is composed of numerous spheroidal granules in the center of the sporocyst. This is the initial species of coccidian reported from G. monarchus and one of the few reported from any reptile from Peninsular Malaysia.

    Matsui M, Jaafar I
    Zoolog Sci, 2006 Jul;23(7):647-51.
    PMID: 16908965
    We describe a new species of cascade frog of the genus Rana, from west Malaysia. Rana monjerai, new species is a medium-sized frog of the subgenus Odorrana (SVL of males, 38-43 mm; of one female, 75 mm), and is distinguished from all other members of this subgenus by the combination of: white lip stripe, dorsolateral fold, full web on the fourth toe, vomerine teeth, gular vocal pouch and relatively large tympanum in males, no dorsal marking, no clear light spots on rear of thigh, first finger subequal to second, finely tuberculated dorsum, and unpigmented ova. The significance of finding this species from peninsular Malaysia is discussed.

  5. A new genus and two new species of trypanorhynch cestodes (Tentaculariidae) from the sharksCarcharhinus sorrah(Müller & Henle) andSphyrna lewini(Griffith & Smith) from off the coasts of Malaysia and Mexico
    Palm HW, Morales-Ávila JR, Galván-Magaña F, Haseli M
    Syst Parasitol, 2020 04;97(2):133-142.
    PMID: 32065375 DOI: 10.1007/s11230-020-09904-w
    Two new tentaculariid species were found infecting carcharhiniform sharks from off the coasts of Malaysian Borneo and the southwestern coast of the Baja California Sur, Mexico. Both new species exhibit a homeoacanthous heteromorphous basal and a homeoacanthous homeomorphous metabasal armature. Since this hook arrangement is unique within the tentaculariids and the taxonomy in this group deeply depends on the tentacular armature, Reimeriella n. g. is erected to accommodate R. varioacantha n. sp. ex Carcharhinus sorrah (Müller & Henle) and R. mexicoensis n. sp. ex Sphyrna lewini (Griffith & Smith). Unlike R. mexicoensis n. sp., R. varioacantha n. sp. has a pars bothrialis not overlapping the pars bulbosa and the number of testes is higher. Reimeriella mexicoensis n. sp. possesses very large uncinate to falcate hooks in the basal armature, while in R. varioacantha n. sp. these hooks are almost the same in size as the remaining hooks in both the basal and metabasal armature. The latter species is the first tentaculariid species where the metabasal armature very closely resembles an eutetrarhynchid with a heteroacanthous typical homeomorphous metabasal armature and a high number of spiniform hooks per half spiral row (10-11 vs 6-7 in R. mexicoensis n. sp.) in the metabasal and apical armature. This pattern provides further morphological evidence for the close relationship of the Eutetrarhynchoidea and the Tentacularioidea. Reimeriella varioacantha n. sp. enriches the trypanorhynch fauna from off the coast of Malaysian Borneo while R. mexicoensis n. sp. is a novel record of a tentaculariid trypanorhynch from the Mexican Pacific.

  7. A new species and locality record for Pseudopsyra katydid (Orthoptera: Phaneropterinae)
    Tan MK, Dawwrueng P, Artchawakom T
    Zootaxa, 2017 Feb 13;4231(4):zootaxa.4231.4.12.
    PMID: 28264411 DOI: 10.11646/zootaxa.4231.4.12
    Pseudopsyra is a genus of Phaneropterinae katydid (Orthoptera: Tettigoniidae), currently comprising of four species - two species each from southern China and Peninsular Malaysia (Hebard, 1922; Liu & Kang, 2006; Tan & Kamaruddin, 2013, 2014). The revision of Pseudopsyra by Liu & Kang (2006) provided a redescription of the genus, a new diagnosis and a key to known species. Subsequently, more surveys were conducted in Peninsular Malaysia and yield another species, representing the lowest latitudinal limits of this genus thus far (Tan & Kamaruddin, 2013). Continued surveys between the upper and lower latitudinal limits of the genus yield a new species: Pseudopsyra taksini sp. nov. from the Sakaerat Biosphere Reserve, Thailand. The orthopteran diversity at Sakaerat Biosphere Reserve remains understudied with numerous new species described recently, including other genus of Phaneropterinae (Tan & Artchawakom, 2014; Tan et al., 2015). With emphasis of using sexual parts for evidence of reproductive isolation in species delimitation, the discovery of a new species of Pseudopsyra also represents the first record of the genus from Thailand. It is not surprising that more undescribed species of Pseudopsyra can be found across the Indo-China region.

  8. A new species of Aberrapex Jensen, 2001 (Cestoda: Lecanicephalidea) from Taeniura lymma (Forsskål) (Myliobatiformes: Dasyatidae) from off Sabah, Malaysia
    Jensen K
    Syst Parasitol, 2006 Jun;64(2):117-23.
    PMID: 16612652
    A new lecanicephalidean species of Aberrapex Jensen, 2001 is described from the blue-spotted fantail ray Taeniura lymma (Forsskål) collected off the eastern coast of Sabah in Malaysian Borneo. This is the first record of a lecanicephalidean tapeworm from the island of Borneo and the first record of Aberrapex from this host species. A. manjajiae n. sp. is easily distinguished from its two congeners, A. senticosus Jensen, 2001 and A. arrhynchum (Brooks, Mayes & Thorson, 1981) Jensen, 2001, based on its overall smaller size (928-1,971 vs 1,485-6,333 and up to 3,350 microm long, respectively) and fewer testes (10-19 vs 20-40 and 18-25, respectively). In addition, A. manjajiae n. sp. is readily distinguished from A. senticosus based on a more anteriorly positioned genital pore (76-85 vs 52-72% of proglottid length from posterior end) and its distal bothridial microthrix pattern. A. manjajiae n. sp. can be further distinguished from A. arrhynchum based on its smaller scolex (82-101 x 119-164 vs 177-186 x 233-326 microm). The host distribution of Aberrapex is expanded from the Myliobatidae to include the Dasyatidae.

  10. A new species of Hemiphyllodactylus Bleeker, 1860 (Squamata: Gekkonidae) from northwestern Thailand
    Grismer LL, Wood PL, Cota M
    Zootaxa, 2014;3760:67-78.
    PMID: 24870072 DOI: 10.11646/zootaxa.3760.1.4
    A new species of gekkonid, Hemiphyllodactylus chiangmaiensis sp. nov., from northwestern Thailand is separated from all other species of Hemiphyllodactylus by a set of features including: a maximum SVL of 41.2 mm; 8-12 chin scales extending transversely from unions of second and third infralabials and posterior margin of mental; lamellar formula on hand 3-3-3-3 or 3-4-3-3; lamellar formula on foot 3-3-3-3 or 3-4-4-4; continuous precloacal and femoral pores; a unique dorsal color pattern; and caecum and oviducts pigmented. These characters place this species in the speciose H. typus group. Hemiphyllodactylus chiangmaiensis sp. nov. fills a biogeographical hiatus in the distribution of this genus across northern Indochina.

    Zoolog Sci, 2009 Aug;26(8):579-85.
    PMID: 19719411 DOI: 10.2108/zsj.26.579
    A new microhylid, Kalophrynus yongi, Is described from the Cameron Highlands of Peninsular Malaysia. Morphologically, the new species differs from all known congeners by having a very stout forelimb with a humeral spine in males. Acoustically, it resembles K. baluensis and K. heterochirus and sharply differs from K. interlineatus, K. pleurostigma, K. palmatissimus, and K. nubicola.

  12. A new species of Leptolalax from Sarawak, Western Borneo (Anura: Megophryidae)
    Matsui M, Zainudin R, Nishikawa K
    Zoolog Sci, 2014 Nov;31(11):773-9.
    PMID: 25366161 DOI: 10.2108/zs140137
    A new megophryid species is described from southwestern Sarawak, Malaysian Borneo. In appearance, Leptolalax marmoratus sp. nov. is most similar to L. hamidi also from southwestern Sarawak, but differs from it by mtDNA sequence, larger body size, and higher dominant frequency of advertisement call. The assumption that more than one species of Leptolalax coexist at one locality in Borneo is supported. The finding of the new species raises the species number of Leptolalax known from Borneo to nine, and the island is thought to be one of the diversification centers of the genus.

    PMID: 32786177 DOI: 10.24272/j.issn.2095-8137.2020.139
    We report on a new species, Micryletta dissimulanssp. nov., from the lowland forests of southern Thailand, which is described based on molecular and morphological evidence. The new species is characterized by a combination of the following characters: small body size (20.3-22.4 mm in males, 24.4-26.7 mm in females); slender body habitus; head longer than wide; snout rounded in dorsal and lateral view; eye length equal to snout length; tibiotarsal articulation reaching to tympanum; dorsal surface slightly granulated to shagreened; supratympanic fold indistinct, ventrally edged in black with large black spot behind eye; outer metatarsal tubercle absent; dorsum reddish-brown with merging irregular-shaped brown blotches edged in beige, no black spots on dorsum; body flanks brown with large black spots edged in whitish mottling, two large black blotches in axillary and inguinal areas on each side; lateral sides of head black, with white patches on lips absent, whitish mottling on tympanum and axillary region; ventral surface pinkish to bluish-gray, translucent, laterally with dark-brown marbled pattern, medially immaculate; throat in males dark-gray with sparse white mottling laterally; iris copper-orange. The new species is divergent from all other congeners in 16S rRNA gene sequences (5.0%-7.4%). To date, Micryletta dissimulanssp. nov. is only known from a single locality in Saba Yoi District, Songkhla Province, Thailand, at an elevation of 120 m a.s.l., but is also expected to occur in neighboring parts of Malaysia. We suggest Micryletta dissimulanssp. nov. be considered as a Data Deficient (DD) species following the IUCN's Red List categories (IUCN Standards and Petitions Committee, 2019).

  14. A new species of genus Nishada Moore, 1878 (Lepidoptera, Erebidae, Arctiinae) from India
    Joshi R, Kirti JS, Singh N
    Zootaxa, 2016 Oct 28;4179(1):128-132.
    PMID: 27811698 DOI: 10.11646/zootaxa.4179.1.10
    Genus Nishada Moore (1878) was proposed as a monotypic genus, under subfamily Lithosiinae, family Lithosiidae (now Lithosiini), including only Nishada flabrifera Moore (1878) from Calcutta (now as Kolkata), India. The genus is distributed from China to India, Thailand, Malaysia and up to Australia. The Indian fauna of Nishada is reported from North-East Himalayas, West Bengal (Kolkata) and South India. Members of this genus are unmarked, yellow to brown with short and broad wings. Genus Nishada has been taxonomically dealt by many authors but awaits thorough revision.

    HISTORY: Hampson (1900) included a total of ten species: Nishada niveola Hampson, 1900, Nishada syntomioides (Walker, 1862), Nishada impervia (Walker, 1865), Nishada marginalis (Felder 1875), Nishada tula Swinhoe, 1900, Nishada nodicornis (Walker 1862), Nishada rotundipennis (Walker 1862), Nishada flabrifera Moore, 1878, Nishada sambara (Moore 1859) and Nishada xantholoma (Snellen 1879). Swinhoe (1902) and Hampson (1911) then described two new species, Nishada melanistis and Nishada brunneipennis, respectively, followed by Rothschild (1912, 1913) who described a further seven new species, Nishada brunnea, Nishada flavens, Nishada testacea, Nishada griseoflava, Nishada fuscofascia, Nishada louisiadensis and Nishada aurantiaca, bringing the total to 19 species. Strand (1922) catalogued only 13 of these species in Nishada, transferring N. brunnea and N. fuscofascia to genus Scoliacma Meyrick (1886); N. testacea, N.griseoflava and N. louisiadensis Rothschild to Eilema Hübner (1819) and synonymising N. flavens with N. sambara. Next, Matsumura (1927) described N. formosibia, followed by two more species, N. aureocincta Debauche, 1938 and N. benjaminea Roepke, 1946. Holloway (2001) synonymised N. nodicornis with N. rotundipennis and added the description of a new subspecies, Nishada chilomorpha adunca Holloway, 2001 from Borneo, indicating a distributional range as far as North East India. The nominotypical subspecies, N. c. chilomorpha was suggested to be restricted to its type locality of Java. Bucsek (2012) added Nishada cameronensis, Dubatolov & Bucsek (2013) described Nishada schintlmeisteri and Bucsek (2016) described Nishada temenggora. So, at present, Nishada comprises19 species, of which three are known from India (Singh et al. 2014). Herein, we describe one further species, Nishada pseudochilomorpha Joshi & Singh sp. nov., from Jatinga (Assam, India). In addition, new distributional records are reported for N. flabrifera.

  15. A new species of insular Rock Gecko (Genus Cnemaspis Strauch, 1887) from the Bidong Archipelago, Terengganu, Peninsular Malaysia
    Grismer LL, Jr PL, Ahmad AB, Sumarli AS, Vazquez JJ, Ismail LH, et al.
    Zootaxa, 2014;3755:447-56.
    PMID: 24869832 DOI: 10.11646/zootaxa.3755.5.4
    A new insular species Cnemaspis bidongensis sp. nov. (Squamata: Gekkonidae), is described from Pulau Bidong, Terengganu, Peninsular Malaysia and bears a unique suite of morphological and color pattern characters that differentiate it from all other congeners. Cnemaspis bidongensis sp. nov. is the sister species to C. kendallii (Gray) and represents the fifth insular endemic species of Cnemaspis on archipelagos along the east coast of Peninsular Malaysia. This species survived massive deforestation of the small island of Bidong (260 ha) from the mid 1970s to the early 1990s when the island served as a Vietnamese refugee camp and harbored as many as 40,000 people at one time. We hypothesize that this species' generalized lifestyle contributed to its survival, allowing it to seek refuge in rocky microhabitats.

  16. A new species of karst forest-adapted Bent-toed Gecko (genus Cyrtodactylus Gray, 1827) belonging to the C. sworderi complex from a threatened karst forest in Perak, Peninsular Malaysia
    Grismer LL, Belabut DM, Quah ES, Onn CK, Wood PL
    Zootaxa, 2014;3755:434-46.
    PMID: 24869831 DOI: 10.11646/zootaxa.3755.5.3
    A new species of Bent-toed Gecko Cyrtodactylus guakanthanensis sp. nov. of the C. sworderi complex is described from a limestone forest in Perak, Peninsular Malaysia whose karst formations at the type locality are within an active quarry. Cyrtodactylus guakanthanensis sp. nov. can be distinguished from all other Sundaland species by having the following suite of character states: adult SVL 77.7-82.2 mm; moderately sized, conical, weakly keeled, body tubercles; tubercles present on occiput, nape, and limbs, and extend posteriorly beyond base of tail; 37-44 ventral scales; no transversely enlarged, median, subcaudal scales; proximal subdigital lamellae transversely expanded; 19-21 subdigital lamellae on fourth toe; abrupt transition between posterior and ventral femoral scales; enlarged femoral scales; no femoral or precloacal pores; precloacal groove absent; wide, dark postorbital stripes from each eye extending posteriorly to the anterior margin of the shoulder region thence forming a transverse band across the anterior margin of the shoulder region; and body bearing five (rarely four) wide, bold, dark bands. Destruction of the karst microhabitat and surrounding limestone forest will extirpate this new species from the type locality and perhaps drive it to complete extinction given that it appears to be restricted to the particular microhabitat structure of the type locality and is not widely distributed throughout the karst formations. As with plants and invertebrates, limestone forests are proving to be significant areas of high herpetological endemism and should be afforded special conservation status rather than turned into cement.

    PMID: 31153893 DOI: 10.1016/j.actatropica.2019.105043
    A new species of black fly, Simulium (Gomphostilbia) rampae, is described, based on adult male, its pupal exuviae and mature larvae collected from Doi Inthanon National Park, northern Thailand. This new species is placed in the Simulium asakoae species-group, and is characterized in the male by the high number of upper-eye facets in 17 vertical columns and 18 horizontal rows, in the pupa by the gill with a long common basal stalk, cone-shaped terminal hook, and cocoon with an anterodorsal projection, and in the larva by the medium-long postgenal cleft. A DNA analysis using COI gene supported its assignment to the S. asakoae species-group and showed its close relationship to S. (G.) udomi Takaoka & Choochote and S. (G.) chiangdaoense Takaoka & Srisuka. This is the fourth member of the S. asakoae species-group recorded from Thailand.

    Biomed Res Int, 2013;2013:412370.
    PMID: 23509722 DOI: 10.1155/2013/412370
    The magnitude of shigellosis in developing countries is largely unknown because an affordable detection method is not available. Current laboratory diagnosis of Shigella spp. is laborious and time consuming and has low sensitivity. Hence, in the present study, a molecular-based diagnostic assay which amplifies simultaneously four specific genes to identify invC for Shigella genus, rfc for S. flexneri, wbgZ for S. sonnei, and rfpB for S. dysenteriae, as well as one internal control (ompA) gene, was developed in a single reaction to detect and differentiate Shigella spp. Validation with 120 Shigella strains and 37 non-Shigella strains yielded 100% specificity. The sensitivity of the PCR was 100 pg of genomic DNA, 5.4 × 10(4) CFU/ml, or approximately 120 CFU per reaction mixture of bacteria. The sensitivity of the pentaplex PCR assay was further improved following preincubation of the stool samples in gram-negative broth. A preliminary study with 30 diarrhoeal specimens resulted in no cross-reaction with other non-Shigella strains tested. We conclude that the developed pentaplex PCR assay is robust and can provide information about the four target genes that are essential for the identification of the Shigella genus and the three Shigella species responsible for the majority of shigellosis cases.

  19. Fulltext A phylogeny of the family Poritidae (Cnidaria, Scleractinia) based on molecular and morphological analyses
    Kitano YF, Benzoni F, Arrigoni R, Shirayama Y, Wallace CC, Fukami H
    PLoS One, 2014;9(5):e98406.
    PMID: 24871224 DOI: 10.1371/journal.pone.0098406
    The family Poritidae formerly included 6 genera: Alveopora, Goniopora, Machadoporites, Porites, Poritipora, and Stylaraea. Morphologically, the genera can be differentiated based on the number of tentacles, the number of septa and their arrangement, the length of the polyp column, and the diameter of the corallites. However, the phylogenetic relationships within and between the genera are unknown or contentious. On the one hand, Alveopora has been transferred to the Acroporidae recently because it was shown to be more closely related to this family than to the Poritidae by previous molecular studies. On the other hand, Goniopora is morphologically similar to 2 recently described genera, Machadoporites and Poritipora, particularly with regard to the number of septa (approximately 24), but they have not yet been investigated at the molecular level. In this study, we analyzed 93 samples from all 5 poritid genera and Alveopora using 2 genetic markers (the barcoding region of the mitochondrial COI and the ITS region of the nuclear rDNA) to investigate their phylogenetic relationships and to revise their taxonomy. The reconstructed molecular trees confirmed that Alveopora is genetically distant from all poritid genera but closely related to the family Acroporidae, whereas the other genera are genetically closely related. The molecular trees also revealed that Machadoporites and Poritipora were indistinguishable from Goniopora. However, Goniopora stutchburyi was genetically isolated from the other congeneric species and formed a sister group to Goniopora together with Porites and Stylaraea, thus suggesting that 24 septa could be an ancestral feature in the Poritidae. Based on these data, we move G. stutchburyi into a new genus, Bernardpora gen. nov., whereas Machadoporites and Poritipora are merged with Goniopora.

    Twenty seven filamentous fungal strains representing five genera; Aspergillus, Penicillium, Trichoderma, Myriodontium and Pleurotus were isolated from four sources; domestic wastewater sludge cake (SC) from IWK (Indah Water Konsortium) wastewater treatment plant, palm oil mill effluent compost from Sri Ulu palm Oil Processing Mill, compost of plant debris, and fungal fruiting bodies from a rotten wood stump. Thirty-three strains/isolates were tested for their ability to convert domestic wastewater sludge into compost by assessing biomass production and growth rate on sludge enriched media. The strains/isolates Aspergillus niger, SS-T2008, WW-P1003 and RW-P1 512 produced the highest dry biomass at higher sludge supplemented culture media from their respective group (Aspergillus, Trichoderma, Penicillium and Basidiomycetes, respectively). This implied these strains are better adapted for growth at higher sludge rich substances, and subsequently may be efficient in bioconversion/biodegradation of sludge. The fungi isolated from ecological closely related sources were more amendable to adaptation in a sludge rich culture media.
