    A new genus and species, Portentus marschneri Trzna Baa gen. nov. sp. nov. (Anthribidae: Anthribinae: Phloeophilini), from Penang National Park, Malaysia is described. Male genitalia are studied and illustrated and colour photographs are provided. A key is provided to distinguish Portentus from similar Palaearctic and Oriental genera of the tribe Phloeophilini: Phloeophilus Schoenherr, 1833, Bothrus Wolfrum, 1956, and Morimotanthribus Senoh Trzna, 2006.

    The Rhoptrobothriidae are one of the more enigmatic families of cestodes of elasmobranchs. Opinions on the taxonomic status of the familys three original genera (i.e., Myzophyllobothrium, Rhoptrobothrium, and Myzocephalus) have varied over the 115 years since they were erected. Some authors have considered all three valid, others have considered Rhoptrobothrium to be a synonym of Myzopyllobothrium or a genus inquirendum, yet others have considered Myzocephalus to be a synonym of the phyllobothriid genus Thysanocephalum. All three genera were established for specimens collected from eagle rays off Sri Lanka. The erection of Mixophyllobothrium for two specimens from a cowtail stingray off India three decades ago added additional confusion to the situation, with some authors considering it valid and others a synonym of Myzocephalus. These disagreements stem largely from differences in interpretation of the complex morphology of the scolex of members of these genera. Furthermore, with the exception of Rhoptrobothrium comprising four species, each genus is monotypic. All but Rhoptrobothrium has not been considered in detail for nearly a century, largely because of a lack of available material. The taxonomic status of these genera is assessed here based on light and scanning electron microscopy, and molecular data generated from new material collected from eagle rays off Indonesian and Malaysian Borneo, Japan, Sri Lanka, and Viet Nam. Morphological work indicates that the genera differ largely only in the degree of folding of the four remi that extend from the cephalic peduncle. A molecular phylogeny based on sequence data for the D1D3 region of the 28S rRNA gene, which include new data for eight specimens of four species, indicates that Myzophyllobothrium, Myzocephalus, and Rhoptrobothrium are not mutually monophyletic. The latter two genera and Mixophyllobothrium are considered synonyms of Myzophyllobothrium and five species are transferred to that genus. Myzophyllobothrium okamuri n. comb. is considered a species inquirendum. Myzophyllobothrium nagasawai n. sp. is described from Aetobatus narutobiei off Japan. Myzophyllobothrium narinari n. comb. is re-described based on newly collected cestodes from the type host and locality (i.e., Aetobatus ocellatus off Sri Lanka). Despite consisting of only a single genus, the family status of the group is retained in recognition of the unusual configuration of the scolex, which bears four biloculate bothridia and four remi extending from the cephalic peduncle. The ordinal placement of the family remains uncertain, but affinities with the Phyllobothriidea, rather than Tetraphyllidea are considered.

    Zootaxa, 2021 Jun 11;4985(1):6980.
    PMID: 34186672 DOI: 10.11646/zootaxa.4985.1.3
    Six new species of the genus Sicciaemorpha van Eecke, 1920 which was previously considered to be monotypic are described: S. yumun sp. n. (Malaysia: northern Borneo Island), S. langgona sp. n. (the Philippines: Mindanao Island), S. nebulibia sp. n. (the Philippines: Luzon Island), S. pleiadina sp. n. (the Philippines: Mindanao Island), S. danepan sp. n. (the Philippines: Mindanao Island), and S. reducta sp. n. (the Philippines: Mindanao Island). Lectotype is designated for the type species of the genus, Sicciaemorpha ivyalba van Eecke, 1920. Adults, male and female genitalia are illustrated.

    The agamid genus Bronchocela Kaup, 1827 comprises 13 species of diurnal, arboreal lizards distributed from India east through Myanmar, Thailand, Cambodia, Vietnam, Malaysia, Singapore, Indonesia, the Philippines, to Papua New Guinea (Diong Lim 1998; Hallermann 2005; Grismer et al. 2015). Once occupying this entire range, B. cristatella's distribution has now been restricted to the Andaman and Nicobar Islands, southern Thailand, Malaysia, Singapore, Indonesia, the Philippines, and Papua New Guinea (Hallermann 2005). My intention here is to: 1) clarify the type species of the genus-group name Bronchocela; 2) resolve the valid name for the taxon under consideration; 3) designate lectotypes for Agama cristatella Kuhl, 1820 and Agama gutturosa Merrem, 1820, and; 4) discuss the type locality for the taxon under consideration.

    Although the first issue of Zootaxa appeared in 2001 it was not until two years later, in August 2003, that this aspiring and inspiring new journal issued the first paper on the insect Order Thysanoptera, in Volume 268. Moreover, it was not until February 2005 that the second paper concerning this group appeared in Zootaxa. The subsequent expansion is summarized most succinctly by the number of Thysanoptera papers that appeared in Zootaxa in each of the four five-year periods of these two decades: 5; 40; 92; 134 (see Table 1). The 270 papers concerning this group of insects that appeared in Zootaxa over the 20-year period involved more than 120 authors. These papers were submitted by workers from about 30 different countries, but most of them were from areas of high but previously unexplored species diversity, particularly Australia, Brazil, China, India, Iran, Japan and Malaysia. However, significant contributions were submitted from the far north, including Poland and Russia, as well as the far south, such as Argentina and New Zealand. One reason for the popularity of Zootaxa amongst workers on thrips is presumably the knowledge that this section is edited by two active students of these insects. The editors are pleased to have rejected no more than five papers over these two decades, but they provide much help to authors in shaping manuscripts to ensure that the submitted information is both appropriate, scientifically correct, novel and clearly expressed. Moreover, the journal ensures that manuscripts are published very quickly, usually within four weeks of acceptance by the editors. For the readers a further advantage of Zootaxa is that just over 50% of the published articles on Thysanoptera are freely available on the web, as authors have arranged for Open Access. The thrips publications issued in Zootaxa have included descriptions of 563 new species and 41 new genera of Thysanoptera. These new species represent 9% of the 6300 valid extant species currently listed in this Order, and the new genera represent 5% of the 780 currently recognized genera (ThripsWiki 2021). Many of the publications are only of one or two pages and are issued as Correspondence. Each of these deals with a single new species, or a previously unknown male of a species, or some new and particularly unusual record for a country or host plant. At the opposite extreme are the Monographs that involve revisions of all of the species in a genus, such as the 60 species recognised in the South American genus Holopothrips, or the 30 species known in the worldwide genus Mycterothrips. Others provide illustrated keys to large numbers of genera, such as the 100 genera of Phlaeothripinae that have been recorded from South East Asia. Such extensive studies provide the factual resource on which many of the Articles published in Zootaxa are based. These Articles range from taxonomic revisions of small genera, or of the species found in particular geographic areas, through studies on character state variation and homologies, to historical accounts and catalogues. The very considerable increase in information in recent years about the taxonomic and biological diversity of this group of insects (Mound Hastenpflug-Vesmanis2021) owes much to the existence of the journal Zootaxa.

    The genus Surenus Distant, 1901 (Hemiptera: Heteroptera: Pentatomoidea: Pentatomidae: Pentatominae: Halyini) is revisited and found to be a junior subjective synonym of the genus Agathocles Stål, 1876 (currently Pentatominae: Rolstoniellini). The genus Agathocles and its type species, Agathocles limbatus Stål, 1876, are redescribed. Lectotype of Surenus normalis Distant, 1901 (= Agathocles normalis (Distant, 1901) comb. nov.) is designated and the unknown male of the species is described. Agathocles yunnanensis Zhang Lin, 1984, syn. nov., is considered junior subjective synonym of A. limbatus. Two new species are described: Agathocles flavipes sp. nov. from India (Andhra Pradesh, Karnataka, Maharashtra, and Tamil Nadu) and A. joceliae sp. nov. from Malaysia (Kelantan, Perak). The new species differ from their congeners mainly by the morphology of mandibular plates, length of antennomeres I, IIa and IIb, body length, and structure of male genitalia. Agathocles dubius Distant, 1921 is transferred to the genus Caystrus Stål, 1861 (Pentatominae: Caystrini) based on examination of its holotype with the resulting new combination: Caystrus dubius (Distant, 1921), comb. nov. One new combination is proposed, Paramecocoris ruficornis (Fieber, 1851), comb. nov. (from preoccupied Paramecus Fieber, 1851), and its type locality is clarified as Tenasserim (south Myanmar). Gender agreement and authorship of the name Riazocoris niger Ahmad Afzal, 1977 in Ahmad et al. (1977: 161) are corrected and status of its name bearing type is clarified as lectotype. The following new distribution records are given: A. limbatus from Cambodia, China (Guangxi, Tibet), Laos and Thailand, A. normalis, Caystrus obscurus (Distant, 1901a) and Critheus lineatifrons Stål, 1869 from Laos, Amasenus corticalis Stål, 1863 from Cambodia, Indonesia (E Kalimantan), Laos, Myanmar and Thailand, and Rolstoniellus boutanicus (Dallas, 1849) from Vietnam. Based on characters of external morphology and genitalia, the genus Agathocles is compared with representatives of the genera Halys Fabricius, 1803 (Halyini), Caystrus (Caystrini), Laprius Stål, 1861 (Myrocheini), and Exithemus Distant, 1902 (currently in Rolstoniellini). As a result, the genus Agathocles is here transferred to the tribe Caystrini. The genus Kyrtalus Van Duzee, 1929 is tentatively placed in Myrocheini based on the presence of sulcate mesosternum and femora provided with teeth.

    Two new species of the genus Stenoloba Staudinger, 1892 (S. mediana, sp. n. and S. fuscobrunnea, sp. n.) are described from Cambodia and Laos respectively, and a new species of the genus Victrix Staudinger, 1879 (V. noloides, sp. n.) from China is described. Stenoloba chlorographa Kononenko Ronkay, 2001 is reported for the first time from China (Xizang), and new distributional data for recently described Stenoloba species from Malaysia are presented.

    The snake genus Cylindrophis Wagler, 1828 belongs to the  monogeneric family Cylindrophiidae comprising 15 species distributed predominately throughout SE Asia, with one extralimital species occurring in Sri Lanka (Bernstein et al. 2020: 535). Cylindrophis lineatus is a rare species known from only eight museum specimens (discussed herein), and a photograph of one live individual from Kuching, Sarawak, East Malaysia (Stuebing et al. 2014: 63). Despite being originally described with Singapore as the type-locality (Blanford 1881: 217, 218), it is currently understood that C. lineatus is endemic to western Sarawak, East Malaysia (Stuebing et al. 2014: 63). Wallach et al. (2014: 204) stated that C. lineatus is also found in Kalimantan, but did not provide any references. This appears to have been followed by Bernstein et al. (2020: 537), who provide a map indicating C. lineatus occurrences in Kalimantan. The original description of Cylindrophis lineatus is conventionally cited as Blanford (1881: 217, 218, pl. 20). Herein, we demonstrate that the authorship and date of publication of this taxon should correctly be Cylindrophis lineatus Dennys, 1880b, and discuss that the type locality should be changed to "Borneo".

    The taxonomic status of Asthenodipsas vertebralis in Borneo has been plagued with uncertainty over the last eighty years. An examination of museum collections resulted in the discovery of a voucher specimen of A. vertebralis from Sarawak, East Malaysia that confirms the presence of the species in Borneo and a previously unrecognised species, Asthenodipsas ingeri sp. nov. from Mount Kinabalu, Sabah. Asthenodipsas ingeri sp. nov. can be differentiated from its congeners by the combination of an absence of preoculars and suboculars, 1st and 3rd pair of infralabials in contact, two pairs of posterior inframaxillaries, supralabials 3-5 (sometimes 3 4) in contact with orbit, 15/15/15 rows of dorsal scales, presence of sharp vertebral keel, and divided subcaudals. This study highlights the importance of careful re-examination of museum collections that could potentially harbour new species hiding in plain sight. These discoveries also add to the growing number of reptile and amphibian species being described from Borneo that shows no signs of abating but are already potentially threatened by the continued deforestation and developments on the island.

    Two new species of the genus Odochilus Harold, 1877 (Coleoptera: Scarabaeidae: Aphodiinae: Odochilini) from the Oriental Region are described as follows: O. shavrini Rakovič Anichtchenko, new species from the Philippines (Mindanao) and O. borneensis Rakovič Anichtchenko, new species from Malaysia (Sarawak). Photographs of their habitus are presented. Differential diagnoses are mentioned.

    The phasmid genus Ramulus Saussure, 1862 belongs to the nominotypical tribe of subfamily Clitumninae of the Phasmatidae. This genus consists of 159 species distributed in India (21 species), Sri Lanka (6 species), Bhutan (1 species), Myanmar (6 species), Thailand (1 species), Vietnam (12 species), Malaysia (4 species from Peninsular part and Borneo), Indonesia (18 species from Java, Sumatra, Borneo, Sulawesi, and Key islands), the Philippines (3 species), China including Taiwan (74 species), Japan (1 species), Korea (1 species), and Russia (1 species) (Brock et al., 2021). Three phasmid species have been described in the genus Baculum Saussure, 1861 from the Russian Far East, Korea and North-East China respectively (Bey-Bienko, 1960; Kwon et al., 1992; Chen He, 1994) and later transferred to the genus Ramulus (Otte Brock, 2005). As a result of detailed examination of the type specimens of Ramulus ussurianus (Bey-Bienko, 1960), additional material and descriptions of these species, it became clear that specimens from Russia, Korea and North-East China are conspecific.

    The taxonomy of the little-known cricket genus Changiola from the subfamily Pteroplistinae is reviewed here. This genus consisted of three species, two from Malay Peninsula and one from Indochina. Here, we describe a new species from Borneo, the first from the island: Changiola sarawakensis n. sp. We also provide a key to the species, although it is likely that more species will be added to this genus with more sampling in the region.

    Cyana Walker, 1854 is one of the most species-rich Erebiidae genera within the tribe Lithosiini Billberg of the subfamily Arctiinae Leach. The genus is widespread from Sub-Saharan Africa and Madagascar through southern and eastern Asia to New Guinea and Australia with a diversity hot spot in South East Asia. A striking species with contrasting red and orange wing pattern, C. bellissima (Moore, 1878) was described from northern India and recorded from the Himalayas, China and Indochina (Fang 2000; Černý Pinratana 2009; Singh et al. 2020). Another closely related species, C. stresemanni (Rothschild, 1936) (= bellissima inouei Kishida, 1993) is distributed in the Peninsular Malaysia (Rothschild 1936; Kishida 1993; Bucsek 2012). During examination of extensive unsorted Lithosiini materials housed in the MWM/ZSM and the private collection of the senior author, a series of peculiar specimens from southern Vietnam provisionally identified as 'C. bellissima' was found. These specimens, however, display certain external differences from other populations of C. bellissima and C. stresemanni, suggesting the presence of a further taxon related to C. bellissima. The examination of the male and the female genitalia of the southern Vietnamese specimens has confirmed their specific distinctness and they are described in this paper as a new species.

    Based on material collected by canopy fogging in forests on Borneo, Obhylius arboricola gen. nov., sp. nov., and Seticotasteromimus brunomanseri sp. nov., the second species of this genus, are described. Further records of the type species of Seticotasteromimus Germann, 2013, S. jarawa Germann, 2013, are presented from Borneo, some 2700 km distant from the type locality on the Andaman Islands. Along with Seticotasteromimus, the new genus is best placed in the subtribe Cotasteromimina.

    A new peculiar, spiky, and yellowish species of the genus Tegotettix Hancock, 1913 is described from the Davao region of the island of Mindanao (the Philippines)-T. derijei sp. n. (Mindanao horned pygmy devil). The species is visually similar to T. cristiferus (Günther, 1935) from Borneo and T. armatus Hancock, 1913 from Borneo, which is the type species of the genus, and of which a new record from Sabah is also presented in the study. The new species is also similar to an undescribed species from Bukidnon, which we presented by photographs in its natural habitat. To date, T. armatus was known only from old descriptions and drawings and has not been reported for more than 100 years. A brief overview of the species of the genus Tegotettix, with its division into three species groups, is presented.

    Six species are recognised in the genus Lefroyothrips, including one new species from Australia. The metascutal chaetotaxy of two of these species is unique amongst Thripidae. New distribution records given here indicate that four of the species are widely distributed: L. pictus across tropical Africa, L. lefroyi from northern India to Taiwan, L. fasciatus from Malaysia to northern Australia and New Guinea, and L. varatharajani from southern India to New Caledonia and northern Australia. An illustrated key is provided to the six known species in this genus.
