    A new species of semiterrestrial gecarcinucid freshwater crab, Terrathelphusa secula, is described from Danum Valley in Sabah, East Malaysia, eastern Borneo. In the form of its carapace, third maxilliped, and male second gonopod, it most closely resembles T. ovis Ng, 1997, and T. telur Ng, 1997, from eastern Sarawak and Brunei, respectively. It differs markedly from these and other congeners in its proportionately much wider carapace, and a male first gonopod that is strongly curved and sickle-shaped.

    A new species of Argiope Audouin 1826, A. hoiseni new species is described from Perak and Selangor, Peninsular Malaysia based on morphology and DNA information of the mitochondrial (16S rRNA, COI and COII) and nuclear-encoded (H3A, 18S rRNA) molecular markers. Epigynal structure suggested Argiope hoiseni to be similar to A. jinghongensis Yin, Peng Wang 1994, A. luzona (Walckenaer 1841), A. pulchella Thorell 1881 and A. taprobanica Thorell 1887. Molecular sequence data including the new species inferred that it is monophyletic with an intraspecific variation of 0.87-3.59 % based on the 16S+COI+COII+H3A dataset. Phylogenetic analyses also revealed insights into the evolutionary lineages of Argiope species in Southeast Asia as well as corroborated recent taxonomic changes and species synonymies associated with Argiope. Two new distribution records were also reported for A. chloreis Thorell,1877 and A. doleschalli Thorell, 1873 in Peninsular Malaysia.

    Species of eight species-groups (seven named and one unnamed) of Simulium (Simulium) Latreille are revised chiefly based on the adult female and male genitalia. Four species-groups are each divided into more than two groups. Thus, the S. christophersi species-group is divided into two (S. christophersi and S. nebulicola species-groups), the S. griseifrons species-group into six (S. griseifrons, S. grossifilum, S. chungi, S. crocinum, S. indicum and S. yadongense species-groups), the S. malyschevi species-group into two (S. malyschevi and S. pavlovskii species-groups), and the S. melanopus species-group into three (S. melanopus, S. dumogaense and S. iridescens species-groups). The S. crassifilum species-group is merged with the S. variegatum species-group. Simulium fulvipes (Ono) of the former S. malyschevi species-group and S. dentastylum Yang, Chen & Luo of Simulium s. str. species unplaced to species-group are removed from the subgenus Simulium because their male styles are subequal in length to the coxites. A revised classification of species of the 15 species-groups including eight new species-groups of Simulium (Simulium) is presented. Keys to 20 species-groups of Simulium (Simulium) in the Oriental Region are provided for adult females and males.

    Herein are erected several new taxa and taxonomic changes based on a study of the Old World genera of Peiratinae: Sphodrembas gen. nov. is erected for a single new species, Sphodrembas fumipennis sp. nov. from Kenya and Tanzania. Ectomocoris caccabatus sp. nov. is newly described and represents the first record of the genus from the Korean Peninsula. Chaulioleistes gen. nov. is erected for Peirates singularis Stål, 1874, resulting in Chaulioleistes singularis (Stål, 1874) comb. nov. Isdegardes Distant, 1909, described in Acanthaspidinae (=Reduviinae), is considered a junior synonym of the peiratine genus Phalantus Stål, 1863 syn. nov., resulting in Phalantus melanocephalus (Distant, 1909) comb. nov. for the type species of Isdegardes. Lestomerus wroughtoni Bergroth, 1915 is transferred to Brachysandalus Stål, 1866, resulting in Brachysandalus wroughtoni (Bergroth, 1915) comb. nov. The previously proposed synonymy of Polychitonocoris formosus Miller, 1940 with Calistocoris caesareus Reuter, 1881 is corroborated. All of the above taxonomic acts are supplemented with a key to the species of Calistocoris, a key to the species of Pachysandalus, and a key to the peiratine genera of the Old World. Also reported are thirteen new country records for eleven other species: Brachysandalus bicolor (Villiers, 1948) (Kenya, Tanzania); Ectomocoris bimaculatus Schouteden, 1909 (Ghana); Ectomocoris fenestratus (Klug, 1830) (Ghana); Ectomocoris maculicrus (Fairmaire, 1858) (Uganda, Zimbabwe); Lestomerus affinis (Audinet-Serville, 1831) (Malaysia); Lestomerus basilewskyi Villiers, 1962 (Kenya); Lestomerus bicolor (Villiers, 1948) (Kenya); Lestomerus dubius Villiers, 1948 (Cameroon); Pachysandalus schoutedeni Villiers, 1962 (Sudan); Peirates collarti Schouteden, 1931 (Cameroon); Peirates quadrinotatus (Fabricius, 1798) (Malaysia); and Phalantus africanus Stål, 1874 (Ghana).

    Bronchocela celebensis Gray, 1845 is one of the rarest species of the genus, known only from less than 20 museum specimens collected from northern Sulawesi. It is often confused with its similar congener, B. cristatella, which occurs widely throughout the Indonesian Archipelago and Peninsular Malaysia, except on the Sulawesi mainland. Here, we examine the morphology of B. celebensis based on 46 museum specimens including freshly collected individuals, and redescribe the species based on the holotype (by monotypy). We studied the characters of B. celebensis with morphometric comparison to its allopatric congener B. cristatella from the adjacent islands of southern Sulawesi in Indonesia. Based on the current distribution pattern and the apparent threats, we update the conservation status of B. celebensis using the IUCN Red List Criteria and propose that it be considered as a Vulnerable (VU) species endemic to Sulawesi.

    A new species of Ansonia is described based on genetic and morphological differentiation. Ansonia lumut sp. nov. is most closely related to three other Peninsular Malaysian species, A. penangensis, A. malayana, and A. jeetsukumarani but differs from these and other congeners by at least 6.9% sequence divergence at the 12S, 16S rRNA and t-RNA-val genes and the following combination of morphological characters: (1) SVL 21.0-23.6 mm in males, 27.7-31.6 mm in females; (2) first finger shorter than second; (3) interorbital and tarsal ridges absent; (4) light interscapular spot absent; (5) presence of large, yellow rictal tubercle; (6) dorsum black with greenish-yellow reticulations; (7) flanks with small yellow spots; (8) fore and hind limbs with yellow cross-bars; and (9) venter light gray with fine, white spotting.

    A phylogenetic tree and median-joining network based on cytochrome b sequence data revealed clades consistent with morphological differences and geographical distribution of Clarias batrachus (Linnaeus, 1758) in Southeast Asia. AMOVA analysis for variation was significant among populations (P<0.05) and was in agreement with morphological differences. Pairwise differences were significant between Java and Brunei/Borneo, Brunei/Borneo and west Malaysia, and Java and west Malaysia samples (P < 0.05). Closest relationships were found between samples from Brunei/Borneo and Java, and between west Malaysia and Laos-Sumatra. Nine haplotypes were unique to geographical regions. The Java species had high haplotype (1.000 ± 0.126) but low nucleotide (0.017) diversities, suggesting a population bottleneck followed by expansion. However, SSD and Hri (P=0.5) did not support demographic expansion. Instead, purifying selection where mutations occur and accumulate at silent sites is a more acceptable explanation.

    Liopeltis is a genus of poorly known, infrequently sampled species of colubrid snakes in tropical Asia. We collected a specimen of Liopeltis from Pulau Tioman, Peninsular Malaysia, that superficially resembled L. philippina, a rare species that is endemic to the Palawan Pleistocene Aggregate Island Complex, western Philippines. We analyzed morphological and mitochondrial DNA sequence data from the Pulau Tioman specimen and found distinct differences to L. philippina and all other congeners. On the basis of these corroborated lines of evidence, the Pulau Tioman specimen is described as a new species, L. tiomanica sp. nov. The new species occurs in sympatry with L. tricolor on Pulau Tioman, and our description of L. tiomanica sp. nov. brings the number of endemic amphibians and reptiles on Pulau Tioman to 12.

    Species of Devadatta from Borneo are studied using both morphological and molecular methods. As well as D. podolestoides Laidlaw, four new species are recognised from the island: D. aran spec. nov. (holotype ♂, from Pulong Tau National Park, Miri division, Sarawak, Malaysia, deposited in RMNH), D. clavicauda spec. nov. (holotype ♂, from Bukit Mina, Bukit Mina Wildlife Corridor, Sarawak Planted Forest Project, Bintulu division, Sarawak, Malaysia, deposited in RMNH), D. somoh spec. nov. (holotype ♂, from the Sungai Kahei area, Ulu Balui, Kapit division, Sarawak, Malaysia, deposited in RMNH) and D. tanduk spec. nov. (holotype ♂, from Poring Hot Springs, Kinabalu National Park, West Coast division, Sabah, Malaysia, deposited in RMNH). The Philippine taxon D. basilanensis Laidlaw is considered a good species rather than a subspecies of D. podolestoides. The Bornean species plus D. basilanensis are provisionally considered to form a species group, the podolestoides-group, within Devadatta. The species of the podolestoides-group are so similar in morphology and colouration that they are close to truly cryptic species. Two species appear to exhibit character displacement where their ranges overlap with other Devadatta species. A molecular analysis using four markers (COI, 16S, ITS and 28S) is presented. This analysis includes specimens of all species from the podolestoides-group and two Devadatta species from mainland Asia.

    The Sundaland species of the genus Dysphaea were studied using molecular and morphological methods. Four species are recognized: D. dimidiata Selys, D. lugens Selys, D. ulu spec. nov. (holotype ♂, from Borneo, Sarawak, Miri division, Upper Baram, Sungai Pejelai, Ulu Moh, 24 viii 2014; deposited in RMNH) and D. vanida spec. nov. (holotype ♂, from Thailand, Ranong province, Khlong Nakha, Khlong Bang Man, 12-13 v 1999; deposited in RMNH). The four species are described and illustrated for both sexes, with keys provided. The type specimens of the four Dysphaea taxa named by E. de Selys Longchamps, i.e. dimidiata, limbata, semilimbata and lugens, were studied and their taxonomic status is discussed. Lectotypes are designated for D. dimidiata and D. limbata. D. dimidiata is recorded from Palawan (the Philippines) for the first time. A molecular analysis using three markers (COI, 16S and 28S) is presented. This includes specimens of three Sundaland species of the genus (D. lugens missing) and two congeners from other regions (D. basi-tincta and D. gloriosa). Notes and photographs of the male holotype of D. walli Fraser (from Maymyo, Burma) are provided.

    Platiana Schimmel, 1993 is a moderately large genus in Dimini endemic to South East Asia. Hitherto only four species of this genus were known from Peninsular Malaysia. Here, we describe and figure Platiana cechovskyi sp. nov. from the Cameron Highlands. This species is characteristic by its relatively small body, dark coloration, and strongly serrate antennae which are rarely encountered in Dimini. An identification key to the Platiana species from Peninsular Malaysia as well as a distribution map for all known species are provided.

    Canon Solovyev is a small genus belonging to the Parasa-complex of Limacacodidae. It is distributed from northern India to the Malayan Peninsula. The genus previously included two species: C. punica (Herrich-Schäffer) from the Indian region and C. eos Solovyev from Nepal. Canon punica is recorded from China (Yunnan), northern Thailand and Malaysia, but specimens from northern Thailand and probably those from China (Yunnan) represent a new species that is described herein: C. sripanae Pellinen and Solovyev, new species. Externally, C. sripanae is similar to other Canon species, but it differs from punica and eos in hindwing color and male genitalia. The moths studied were collected at UV and mixed lights. Genitalia of the male holotype and a male and female paratypes are figured. Nomenclature of this study is based on Solovyev (2014).
