RESUMO

An integrative taxonomic analysis of Subdoluseps herberti from southern Thailand and Peninsular Malaysia and S. samajaya from Sarawak, East Malaysia (Borneo) recovers the former as paraphyletic with respect to the latter. The analyses recover the three southernmost populations of S. herberti in Peninsular Malaysia as conspecific and the sister lineage of S. samajaya, whereas S. herberti from Thailand and northern Peninsular Malaysia constitute the sister species to S. samajaya plus the southern three Peninsular Malaysian populations. As such, the southern populations are described herein as S. malayana sp. nov. and all three species are referred to as the S. herberti group. Clade boundaries and breaks within this group on the Thai-Malay Peninsula occurring at the Isthmus of Kra, across the Kangar-Pattani line, and between the Thai-Malay Peninsula and Borneo are consistent with phylogeographic patterns of other Sundaic taxa. The discovery of S. malayana sp. nov. continues to underscore the fact that, despite the well-studied nature of the lizard fauna of Peninsular Malaysia, much of it still remains unrealized and for conservation efforts to move forward, field research followed by expeditiously revised taxonomies must continue.

RESUMO

The enigmatic 'Spectacled Flowerpecker'-a probable new bird species from the island of Borneo-was first sighted in the Danum Valley of Sabah, Malaysia in 2009. However, the absence of a holotype specimen has prevented its formal scientific description. Since then only a handful of reports from widely disparate localities across the island have emerged, all from lowland sites and often in close association with fruiting mistletoe. Here, we report the long-awaited capture of a specimen of this putative new species and confirm its morphological and molecular distinctiveness as a novel species in the genus Dicaeum.

RESUMO

Borneoconnus, a subgenus of Euconnus endemic to Borneo, is revised. Euconnus laticlava Franz (type species of subgenus), E. eremita Franz and E. sabahanus Franz are redescribed. Morphological structures of E. laticlava are illustrated and described in detail. It is concluded that Borneoconnus is most similar to Euconnus s. str., Napochus Thomson and Psomophus Casey; differences in morphological structures are discussed. Borneoconnus is maintained as a separate subgenus, pending further study, as this name seems to be a candidate to place as a junior synonym of Napochus in a future reclassification of Euconnus subgenera. The variability in the pronotal form found within otherwise morphologically uniform Borneoconnus species supports a weak taxonomic value of this character to use in subgeneric diagnoses. This observation may result in merging Euconnus s. str. and Napochus Thomson, and possibly also Borneoconnus, in one subgenus. However, the yet unrevised subgenera of Euconnus must be studied before such an action is taken.

RESUMO

The pselaphine genus Sathytes Westwood is represented in Borneo by a single species. In this paper we describe four new species: S. borneoensis sp. nov., S. liuyei sp. nov., S. larifuga sp. nov., and S. shihongliangi sp. nov. All new species were collected by light traps in Sabah, and show unique combinations of male sexual characters that lead to ready species discriminations. A key to Sathytes species from Borneo is appended.

RESUMO

Megasybacodes brevitarsis Kakizoe, Maruyama Masumoto, a new genus and new species of the tribe Rhyparini, is described based on a single female from Borneo. It is allied to the genus Sybacodes Fairmaire, 1896, but easily distinguished by its short protarsi, broad flattened basal tarsomeres of the meso- and metatarsi, broad flattened tibiae, and wrinkled pronotal and elytral surfaces. Checklist of rhyparine species from Borneo is also provided.

RESUMO

Within Sundaland, the species diversity of the genus Megophrys is richest in Borneo, with some species restricted to the northern highlands of the island. On the basis of molecular, morphological and acoustic evidence, we describe a new species of large-sized Megophrys, once confused with M. nasuta. The new species Megophrys kalimantanensis sp. nov. can be differentiated from all its congeners by large genetic distance more than 6.11% in the mitochondrial 16S rRNA gene, much shorter rostral and orbital appendages, and unique advertisement call. This new species has been recorded from medium to high altitudes of mountain forest in southern and northernmost Borneo.

RESUMO

There are numerous pygmy grasshoppers (Tetrigidae) that exhibit leaf-like appearance. Leaf-mimic species can be found mainly in the subfamily Cladonotinae (tribes Cladonotini, Xerophyllini). Two leaf-mimic pygmy grasshopper species found in India, Pakistan (Oxyphyllum pennatum Hancock, 1909) and Borneo (Paraphyllum antennatum Hancock, 1913) are the only macropterous leaf-like species of Asia and were traditionally assigned to subfamily Cladonotinae. Our study present new records of these species, as well as updated descriptions. Oxyphyllum pennatum is recorded for the first time from Chhattisgarh (Central India), and furthermore, records from Pakistan were reviewed and confirmed. Paraphyllum antennatum is reported from a few localities in the mountains of Borneo (East Malaysia). New records found in online social media (Flickr, iNaturalist) were implemented. Brachypronotal specimens of P. antennatum are reported. After comparison with Cladonotini and Xerophyllini members, we conclude that Oxyphyllum and Paraphyllum should not be regarded Cladonotinae members. Traditional assignment was based on superficial resemblance to leaf-like Cladonotinae genera (e.g. Phyllotettix, Hymenotes, Holoarcus, Xerophyllum). However, comparison of morphological characters reveals that Oxyphyllum shares morphology with Tetriginae genera, while Paraphyllum shares morphology with Asian Metrodorinae. Here, we assign the genus Oxyphyllum to Tetriginae and the genus Paraphyllum to Metrodorinae.

RESUMO

Orthoptera from Sandakan, Sabah are relatively understudied compared to some other parts of Borneo, and lack of information of species there can impede our understanding of the origins and biodiversity of orthopterans in Borneo and, in general, Southeast Asia. Based on a recent orthopteran survey in Sandakan, one new species of Lebinthus Stål is described: Lebinthus sandakan sp. nov. The male calling song of this new species is also presented. The calling song of Cardiodactylus borneoe Robillard Gorochov, 2014 is also described for the first time.

RESUMO

The island of Borneo lies within one of the most biodiverse regions in the world. Despite this, its documented gekkonid diversity is not commensurate with other areas of Southeast Asia. The megadiverse genus Cyrtodactylus is especially underrepresented. Limestone-karst ecosystems, in particular, harbor many endemic Cyrtodactylus species, but only one karst-dwelling species is currently recognized from Borneo. This paper adds two additional karst-dwelling Cyrtodactylus species-C. muluensis sp. nov. and C. limajalur sp. nov.-from Sarawak, Malaysia. Cyrtodactylus muluensis sp. nov. is endemic to Gunung Mulu and is distinguished from its congeners by having a precloacal groove, 31-38 ventral scales, a maximum SVL of at least 88 mm, enlarged subcaudals, 19-20 subdigital lamellae, and a banded dorsal body pattern. Cyrtodactylus limajalur sp. nov. is endemic to the Serian region and is distinguished from its congeners by having 33-42 ventral scales, enlarged subcaudals, a precloacal pit, a maximum SVL of at least 94 mm, 5-6 enlarged femoral scales, 19-22 subdigital lamellae, and five distinct bands on the dorsum. Both species are phylogenetically distinct and deeply divergent from all other congeners. The description of two new karst-dwelling species highlights the need to conserve karst habitats and the endemic species they harbor.

RESUMO

The genus Marcepania is a sole member of the tribe Marcepaniini, known to occur in SE Asia. The five hitherto described species inhabit the Malay Peninsula and Borneo. The first species discovered in the Philippines, Marcepania princesa sp. n. is described here, based on a male specimen found on the island of Palawan. It is most similar to its geographically closest relative, M. elongata of northern Borneo.

RESUMO

We collected a specimen of a scincid lizard of Larutia Böhme, 1981 from the edge of a primary forest on Gunung Penrissen, Kuching Division, Sarawak, Malaysian Borneo. The single specimen of the new species differs from all other known congeners by the molecular divergence in the mitochondrial ND1 gene and morphological characters including small adult body size (SVL 84 mm); 22 longitudinal scale rows around midbody; first pair of chinshields contacting second infralabial; second pair of chinshields separated from infralabials by an elongated scale; two subdigital lamellae on second toe; and body without yellow or pale bands or spots. It is the ninth species described in the genus and the second species of Larutia in Borneo.
