A dobsonfly species group, the Protohermes dichrous group, endemic to Borneo, is characterized by the straight directed male ninth gonostylus with a narrow base and the elongate male ectoproct. Protohermes goodgeri sp. nov. and P. karubei sp. nov. from northern Borneo (eastern Malaysia) are herein described as new species placed in the P. dichrous group.
The Oriental genus Stigmothrips Ananthakrishnan is synonymised with A draneothrips Hood, a genus in which most species have been described from the Neotropics. Problems with descriptions by T.N. Ananthakrishnan of species from India are discussed, but cannot be fully resolved without access to the holotypes. A key is provided to 23 species of Adraneothrips from Asia and Australia, including four new species: darwini sp. n. from Northern Territory, Australia; hani sp. n. from Taiwan, China; yunnanensis sp. n. from Yunnan, China as well as Java, Indonesia; and waui sp. n. from Papua New Guinea. One species from the Philippines, Adraneothrips makilingensis (Reyes) comb. n., is transferred from Apelaunothrips, and the male of Adraneothrips russatus (Haga) is described and illustrated for the first time, from Yunnan, China. Two species are newly recorded from Australia: coloratus (Mound) previously known only from the Solomon Islands, and russatus (Haga) previously known from southern Japan and southern China but with one female recorded here from Fiji. Further new records are, coloratus from Java, and chinensis (Zhang & Tong) from Malaysia. Colonies of species in this genus are commonly found living on dead leaves, as fungus-feeders, and many species are brightly coloured or bicoloured in patterns of yellow and brown.
This revision completes a taxonomic survey of fireflies (Coleoptera: Lampyridae) in the area encompassed by Australia, the Republic of Palau, Federated States of Micronesia, Papua New Guinea, Indonesia (West Irian/Papua), Solomon Islands, New Caledonia, Vanuatu and Fiji. It finalises the taxonomic issues arising from the 1969–70 voyage of the scientific vessel Alpha Helix to New Guinea. The firefly fauna of this area is exclusively Luciolinae. The scope of the revision was extended to include all known Luciolinae genera and certain species from SE Asia, and a phylogenetic analysis of 436 morphological characters of males, females, and associated larvae includes 142 Luciolinae species (Ballantyne & Lambkin 2009, and Fu et al. 2012a). The phylogenetic analyses infer four major groups within the Luciolinae. The monotypic Missimia Ballantyne is sister to all remaining Luciolinae and forms a grade to Aquatica Fu etBallantyne. The large clade of Curtos Motschulsky, Photuroluciola Pic, Colophotia Motschulsky, Poluninius gen. nov., Pyrophanes Olivier, Pteroptyx s. str. Olivier, Medeopteryx gen. nov., Trisinuata gen. nov., and Australoluciola gen. nov.forms a grade to the clade of Luciola s. str. Laporte (including Bourgeoisia Olivier). The monotypic Emeia Fu et al.forms a grade with a clade of Luciola and Pygoluciola Wittmer, sister to a large clade of Convexa Ballantyne, Pacifica gen. nov., Magnalata Ballantyne, Lloydiella Ballantyne, Asymmetricata Ballantyne, Pygatyphella s. str. Ballantyne, Atyphella Olliff, Aquilonia Ballantyne, and Gilvainsula Ballantyne. Luciola is paraphyletic, found in up to six clades across the tree. Together with Luciola, Magnalata, Aquilonia, and Gilvainsula render Atyphella paraphyletic. The new genera described here are all monophyletic and supported in the phylogenetic analyses that also provide evidence for the inclusion of taxa within them. Twenty-three genera including five new ones, and ten new species, are recognised and keys are presented for the males and females. Certain females are characterised by the nature of their bursa plates. Australoluciola gen. nov. is proposed for ten species from Australia and New Guinea, seven transferred from Luciola and three new, with species keyed from males, all of which have an entire light organ in ventrite 7. Aus. anthracina (Olivier), Aus. aspera (Olivier), Aus. australis (F.), Aus. flavicollis (MacLeay), Aus. foveicollis (Olivier), Aus. nigra (Olivier) and Aus. orapallida (Ballantyne) are transferred from Luciola with males assigned to Aus. aspera(Olivier), and a lectotype designated for Luciola foveicollis Olivier; Aus. baduria sp. nov., Aus. fuscamagna sp. nov.,Aus. fuscaparva sp. nov., Aus. japenensis sp. nov. and Aus. pharusaurea sp. nov. are described. Females of Aus. australis and Aus. flavicollis have two pairs of wide bursa plates. The bent-winged fireflies of New Guinea and Australia are removed from Pteroptyx Olivier and assigned to Medeopteryx gen. nov. and Trisinuata gen. nov. Medeopteryx gen. nov. is erected for 17 species including two new; all have ventrite 7 with an entire light organ, trisinuate posterior margin and short posterolateral projections; the following 14 species in which males have deflexed elytral apices are transferred from Pteroptyx Olivier: M. amilae (Satô), M. antennata (Olivier), M. corusca (Ballantyne), M. cribellata (Olivier), M. effulgens (Ballantyne), M. elucens (Ballantyne), M. flagrans (Ballantyne), M. fulminea (Ballantyne), M. hanedai (Ballantyne), M. platygaster (Lea), M. similisantennata(Ballantyne), M. sublustris (Ballantyne), M. tarsalis (Olivier), and M. torricelliensis (Ballantyne). M. clipeata sp. nov. is described. Two species without deflexed elytral apices include M. pupilla (Olivier) which is transferred from Luciola, and M. similispupillae sp. nov. A Lectotype is designated for Luciola pupilla (Olivier). Females of M. corusca(Ballantyne), M. cribellata (Olivier), M. effulgens (Ballantyne), and M. similispupillae sp. nov. have two pairs of wide bursa plates. The second genus including species in which the males have deflexed elytral apices is Trisinuata gen. nov., where all males have light organ in ventrite 7 bipartite and posterolateral projections expanded; it is proposed for eight New Guinean species: T. microthorax (Olivier), T. minor (Ballantyne), T. papuae (McDermott) and T. similispapuae(Ballantyne) are transferred from Pteroptyx Olivier, T. papuana (Olivier) previously known only from a female, has males associated and is transferred from Luciola, and T. caudabifurca sp. nov., T. dimidiata sp. nov. and T. apicula sp. nov. are described. Females of T. similispapuae (Ballantyne) have two pairs of wide bursa plates. Luciola s. str. is defined by scoring the type species L. italica (L), Bourgeoisia Olivier and Lampyroidea (based on its type species syriaca Costa) both of which are submerged into Luciola; Luciola s. str is addressed here from four Pacific Island species: L. hypocrita Olivier, L. antipodum Bourgeois both transferred from Bourgeoisia; L. aquilaclarasp. nov. and L. oculofissa sp. nov. are described. L. oculofissa sp. nov. is the only Luciolinae male known to lack light organs. Females of L. italica and L. hypocrita lack bursa plates.Pacifica gen. nov. is proposed for five species from the Solomon Islands transferred from Pygatyphella(Ballantyne), and which the phylogenetic analysis shows to be distinctive viz. P. limbatifusca (Ballantyne), P. limbatipennis (Pic), P. plagiata (Blanchard), P. russellia (Ballantyne), and P. salomonis (Olivier). A monotypic genus Poluninius gen. nov. is proposed for Pol. selangoriensis sp. nov. from Selangor, Malaysia. The genera Colophotia, Pteroptyx, Pyrophanes, and Pygoluciola are treated in an abbreviated fashion with generic diagnoses, lists of, and keys to, species. Pteroptyx bearni Olivier and P. tener Olivier are characterised from type specimens and female bursae and P. similis Ballantyne is synonymised with P. bearni. Luciola semilimbata Olivier is transferred to Pyrophanes, and Luciola cowleyi Blackburn to Pygoluciola. The following species are treated as species incertae sedis: L. melancholica Olivier, L. ruficollis Guérin-Ménéville. The New Guinean records of Luciola tenuicornis Olivier, L. timida Olivier and Photinus cinctellus Motschulsky are suspect. Fifteen of the species treated here are recognised by flashing patterns. The functions of the terminal abdominal modifications, origins of the Australopacific firefly fauna, and use of female and larval characters in interpretations of relationships are considered.
The eagle ray Aetobatus flagellum (Bloch & Schneider, 1801) is redescribed based on new material from the Persian Gulf (Kuwait), Indonesia and Malaysia. A related but distinct species of Aetobatus from the western North Pacific, previously referred to as A. flagellum, is reported. Aetobatus flagellum is a medium-sized eagle ray which attains about 900 mm DW; males mature at approximately 500 mm DW. Aetobatus flagellum appears to be uncommon and restricted to estuary-influenced waters of the Indo-West Pacific. It is caught as gillnet bycatch where its habit of schooling, combined with probable small litter size, may make it particularly vulnerable to impacts from fisheries.
A new species of karst-adapted gekkonid lizard of the genus Cnemaspis Strauch is described from Gua Gunting and Gua Goyang in a karst region of Merapoh, Pahang, Peninsular Malaysia whose unique limestone formations are in immediate danger of being quarried. The new species differs from all other species of Cnemaspis based on its unique suite of morphological and color pattern characters. Its discovery underscores the unique biodiversity endemic to karst regions and adds to a growing list of karst-adapted reptiles from Peninsular Malaysia. We posit that new karst-adapted species endemic to limestone forests will continue to be discovered and these regions will harbor a significant percentage of Peninsular Malaysia's biodiversity and thusly should be conserved rather than quarried.
Species of Apelaunothrips are fungus-feeders on dead leaves, particularly in leaf-litter, and they are recorded across the Old World tropics from Africa to northern Australia and southern Japan. All species in this genus have the maxillary stylets 4-6 microns in diameter, considerably broader than the 2-3 micron diameter that is typical among Phlaeothripinae. The species are largely uniform in structure, but in four species the larger males have fore femora enlarged with a conspicuous tubercle on the inner margin at the base. In one of these species, the males are dimorphic, with no intermediates between large and small individuals, in contrast to the continuous variation in structure found in many polymorphic Phlaeothripidae. A key is provided to the 37 recognised species of Apelaunothrips, including the following: A. desleyae sp.n. from northern Australia; A. bogor sp.n. from Java; A. gombak sp.n. from Peninsular Malaysia.
Paragaleus tengi was previously considered to be the only member of this genus occurring in the Western Pacific, with Paragaleus randalli occurring in the Indian Ocean and allopatric in distribution. Recent molecular and morphological studies showed that P. randalli also occurs in the Western Pacific with records from Thailand, Malaysia and Indonesia previously mostly incorrectly attributed to P. tengi. This paper provides a redescription of P. tengi and confirms the presence of P. randalli from off Taiwan in the western North Pacific. These two species are morphologically very similar in appearance but differ in meristics, dentition, some coloration attributes and minor morphological characters. The conservation status of these two species needs to be reassessed based on this new information.
Molecular and morphological analyses indicate that a new upland species of the Cyrtodactylus sworderi complex, C. tebuensis sp. nov. from Gunung Tebu, Terengganu, Malaysia is most closely related to C. sworderi and together they form the sister lineage to C. quadrivirgatus. Cyrtodactylus tebuensis sp. nov. is differentiated from all other species of Sundaland Cyrtodactylus on the basis of having the unique combination of large, conical, keeled body tubercles; tubercles present on top of head, occiput, nape, and limbs, and extending posteriorly beyond base of tail; 43-51 ventral scales; no transversely enlarged, median subcaudal scales; proximal, subdigital lamellae transversely expanded; 17-21 subdigital lamellae on fourth toe; an abrupt transition between posterior and ventral femoral scales; enlarged femoral scales; no femoral or precloacal pores; no precloacal groove; body bearing four wide, bold, dark brown stripes (lateral stripe on each flank and a pair of paravertebral stripes); and a pairwise sequence divergence of 13.0% from its closest relative C. sworderi based on the mitochondrial gene ND2. Cyrtodactylus tebuensis sp. nov. is the first endemic upland species of gekkonid from northeastern Peninsular Malaysia and underscores the necessity for additional field work in all upland systems.
It has been suggested human female breast size may act as signal of fat reserves, which in turn indicates access to resources. Based on this perspective, two studies were conducted to test the hypothesis that men experiencing relative resource insecurity should perceive larger breast size as more physically attractive than men experiencing resource security. In Study 1, 266 men from three sites in Malaysia varying in relative socioeconomic status (high to low) rated a series of animated figures varying in breast size for physical attractiveness. Results showed that men from the low socioeconomic context rated larger breasts as more attractive than did men from the medium socioeconomic context, who in turn perceived larger breasts as attractive than men from a high socioeconomic context. Study 2 compared the breast size judgements of 66 hungry versus 58 satiated men within the same environmental context in Britain. Results showed that hungry men rated larger breasts as significantly more attractive than satiated men. Taken together, these studies provide evidence that resource security impacts upon men's attractiveness ratings based on women's breast size.
Septesinus gibsoni n. g., n. sp. (Monocotylidae: Heterocotylinae) is described from the gills of the dwarf whipray Himantura walga (Müller & Henle) collected in marine waters off Sarawak (Borneo), Malaysia. Septesinus n. g. is distinguished from other genera in the Monocotylidae by a combination of characters, including a haptor with one central and seven peripheral loculi, the presence of a highly sinuous ridge surmounting all haptoral septa, four rounded accessory structures on the dorsal surface of the haptor, and the anterior region with two pairs of anteromedian and three pairs of anterolateral gland-duct openings. Septesinus n. g. is accommodated in the Heterocotylinae. Septesinus gibsoni n. sp. is described and fully illustrated, and a key to the genera of Heterocotylinae is provided. The composition of the ridges surrounding the mouth of a number of heterocotyline species and their usefulness as a taxonomic character are examined. The identity of four specimens of Monocotyle Taschenberg, 1878, also recovered from the gills of this host species, is discussed.
Digitised monogenean images are usually stored in file system directories in an unstructured manner. In this paper we propose a semantic representation of these images in the form of a Monogenean Haptoral Bar Image (MHBI) ontology, which are annotated with taxonomic classification, diagnostic hard part and image properties. The data we used are basically of the monogenean species found in fish, thus we built a simple Fish ontology to demonstrate how the host (fish) ontology can be linked to the MHBI ontology. This will enable linking of information from the monogenean ontology to the host species found in the fish ontology without changing the underlying schema for either of the ontologies.
The genus Proinalactis Meyrick, 1908 is reviewed in Southeast Asia. Twenty-seven new species are described based on the specimens collected in Malaysia, Thailand, Brunei, Burma, Philippines. The new species include P. alveiformis sp. nov., P. angusta sp. nov., P. bruneiensis sp. nov., P. conicispinalis sp. nov., P. ellipsoidea sp. nov., P. exiliprocessa sp. nov., P. extumida sp. nov., P. fascisetacea sp. nov., P. flagellaris sp. nov., P. foraininulata sp. nov., P. fortijuxtalis sp. nov., P. lancea sp. nov., P. latuncata sp. nov., P. longisaccata sp. nov., P. lophacantha sp. nov., P. medispinata sp. nov., P. palmifolia sp. nov., P. pectinifera sp. nov., P.sectoralis sp. nov., P. semiovata sp. nov., P. sinualis sp. nov., P. spinosicostalis sp. nov., P. strena sp. nov., P. superimposita sp. nov., P. truncatapicalis sp. nov., P. undulata sp. nov. and P. vulvida sp. nov. Promalactis parasuzukiella Wang, 2006 and P. simniliflora Wang, 2006 are recorded from Southeast Asia for the first time. Three species described by Lvovsky are fully redescribed. Images of adults and genitalia are provided, along with a check list of 71 species from Southeast Asia.
Three new species of the uncommonly encountered insect order Zoraptera are described and figured from Peninsular Malaysia--Zorotypus magnicaudelli sp. n., Zorotypus cervicornis sp. n., and Zorotypus impolitus sp. n. Another species from the region, identified as Zorotypus caudelli Karny, 1927, was also collected and is reevaluated herein based on new material. A brief discussion of characters used in zorapteran systematics is provided, and a key to the species of Peninsular Malaysia provided. This is the first report for the order Zoraptera from Peninsular Malaysia.
Leydig and Sertoli cells of the immature lesser mouse deer testes, obtained in East Malaysia, were observed using light and transmission electron microscopy (TEM). The testes were fixed in 5% glutaraldehyde, post-fixed in 1% OsO4, dehydrated in ethanol, and embedded in Araldite M. Serial semi-thin sections were cut, stained with toluidine blue and observed using light microscopy. Serial ultra-thin sections were cut, stained with uranyl acetate and lead citrate, and examined using TEM. As a result, ultrastructurally, two types of underdeveloped filament bundles were infrequently recognized in Leydig cells, but not in other testicular cells. One type was the underdeveloped bundles of actin filaments (approximately 5 nm in diameter), which were found in the nucleus of Leydig cells. The other type was the underdeveloped bundles of intermediate filaments (approximately 10 nm in diameter), which were found in the cytoplasm of Leydig cells. A multivesicular nuclear body (MNB)--specifically present in the Sertoli cell nucleus of ruminant testes--was infrequently observed. The MNB is situated in the vicinity of nuclear membrane, still in an underdeveloped stage.
Myliocotyle borneoensis sp. n. and M. multicrista sp. n. (Monocotylidae: Heterocotylinae) are described from the gills of the mottled eagle ray, Aetomylaeus maculatus (Gray), and the banded eagle ray A. nichofii (Bloch et Schneider) (Myliobatidae), respectively, collected from the northern coast of Malaysian Borneo. These are the first monogeneans to be described on elasmobranchs from Borneo. The formerly monotypic Myliocotyle (for M. pteromylaei) was distinguished from other monocotylids by the distribution and morphology of the eight sclerotised dorsal haptoral accessory structures and the morphology of the male copulatory organ. However, we have determined that M. pteromylaei has ten structures on the dorsal surface of the haptor. Myliocotyle borneoensis is distinguished from M. pteromylaei by the morphology of the male copulatory organ and its accessory piece. Myliocotyle multicrista has 12 sclerotised dorsal haptoral accessory structures and a male copulatory organ with two accessory pieces. Additional sclerotised ridges across the ventral surfaces of each loculus (except the posterior-most pair) are also present in M. multicrista. The diagnosis for Myliocotyle is revised given our discovery of additional dorsal haptoral accessory structures in the type species and to accommodate other new characters of the two new species. Anterior secretions of Myliocotyle are discussed.
The native distribution of the small labyrinth fish species Pseudosphromenus cupanus includes southern India and Sri Lanka. According to literature it has a range including also Pakistan, Bangladesh, Myanmar, Malaysia, and Indonesia (Sumatra) but there are no voucher specimens or reliable observations from those areas. The distribution record of P. cupanus was inflated partly by including P. dayi as a synonym. Pseudosphronemus dayi is native to the Western Ghats in India, but the origin of the aquarium importation in 1907 was reported as both Cochin (=Kochi) and Malacca (=Malaysia), the latter locality obviously in error. The basis for the Sumatra record is an obviously mislabeled sample of P. dayi from Pulau Weh close to Sumatra. The basis for reporting the species from Pakistan, Myanmar or Bangladesh could not be located. Misidentified museum specimens from Myanmar and Pakistan identified as P. cupanus were never published on. Pseudosphromenus cupanus has been considered recently to be extinct in Bangladesh, but in fact it never occurred there.
To date, three species of the genus Glischropus are recognized from the Indomalayan zoogeographic region-G. bucephalus from the Indochinese subregion, G. tylopus from the Sundaic subregion (Peninsular Thailand and Malaysia, Borneo, Sumatra, Moluccas) and G. javanus, restricted to Java. The investigation of the holotype and three topotype specimens of G. batjanus supported the view that the name was previously correctly regarded as the junior subjective synonym of G. tylopus. During review of material recently collected in southwestern Sumatra, Indonesia, one specimen of a yet undescribed species of Thick-thumbed bat was identified. G. aquilus n. sp. markedly differs from its congeners by its dark brown pelage, nearly black ear and tragus, and in skull proportions. The phylogenetic analysis based on cytb sequences also supports the specific distinctness of G. aquilus n. sp. Its discovery brings the count to 88 species of bats known from Sumatra.
Four new species of Calydiscoides Young, 1969 are described from three species of nemipterids caught off Kemaman, Terengganu, on the eastern coast of Peninsular Malaysia: C. monogrammae n. sp. from Scolopsis monogramma; C. conus n. sp. from S. magaritifer; C. scolopsidis n. sp. from S. margaritifer and S. monogramma; and C. kemamanensis n. sp. from Pentapodus setosus. The present investigation reveals that the squamodiscs (lamellodiscs) are composed of 10-12 short, complete, interlocking and concentric tubular lamellae. The innermost lamella is attached to a pair of adductor muscles.
Fruit type in the genus Lithocarpus (Fagaceae) includes both classic oak acorns and novel modifications. Bornean taxa with modified fruits can be separated into two sections (Synaedrys and Lithocarpus) based on subtle shape differences. By following strict criteria for homology and representation, this variation in shape can be captured and the sections distinguished by using elliptic Fourier or eigenshape analysis. Phenograms of fruit shape, constructed by using restricted maximum likelihood techniques and these morphometric descriptors, were incorporated into combined and comparative analyses with molecular sequence data from the internal transcribed spacer (ITS) region of the nuclear rDNA, using branch-weighted matrix representation. The combined analysis strongly suggested independent derivation of the novel fruit type in the two sections from different acornlike ancestors, while the comparative analysis indicated frequent decoupling between the molecular and morphological changes as inferred at well-supported nodes. The acorn fruit type has undergone little modification between ingroup and outgroup, despite large molecular distance. Greater morphological than molecular change was inferred at critical transitions between acorn and novel fruit types, particularly for section Lithocarpus. The combination of these two different types of data improved our understanding of the macroevolution of fruit type in this difficult group, and the comparative analysis highlighted the significant incongruities in evolutionary pattern between the two datasets.
The data on thyroid volume measurements that determines prevalence of goitre in children is very important for public health consideration as the presence of goitre in children effectively reflects the status of iodine deficiency disorders (IDD) in the general population. Ultrasound is an excellent modality to evaluate thyroid size. Local experience in using a portable ultrasound machine to measure thyroid volume is presented. The thyroid anatomy and techniques of ultrasound assessment are highlighted. Proper training of public health doctors to perform thyroid gland ultrasonography is crucial to ensure that the thyroid volume data collected would be more accurate and reliable for the planning of health programmes to eliminate IDD in the particular areas.
