A New Species

Recent taxonomic and systematic research on Cyrtodactylus khasiensis has found that this nomen comprises a large number of superficially similar but deeply divergent species-level taxa from throughout north-east India and surrounding countries. In this study we focus on the taxonomic status of recently surveyed populations from the East Garo Hills and West Garo Hills districts and a single specimen collected from Ri Bhoi District in Meghalaya State, north-east India. Based on a combination of morphological and molecular data we found that the Ri Bhoi specimen is conspecific with the recently described C. urbanus, and that the Garo Hills populations represent a new species of Cyrtodactylus described herein. Molecular analyses (using the NADH dehydrogenase 2, nd2 and adjoining tRNA genes) demonstrate that the new species is nested within the khasiensis group of the Indo-Burma radiation of Cyrtodactylus, and is well-supported as sister to a clade that comprises C. septentrionalis and C. guwahatiensis. We morphologically compare the new C. urbanus specimen with the original description of the species, identify a number of errors and ambiguities in the original description, and notably expand the known morphological variation for the species based on 23 characters. The discovery of an endemic new species of lizards from the Garo Hills further highlights the region as an overlooked centre of biodiversity importance. We discuss several misidentifications in the literature of other reptile species from the region emphasising the need for further attention by taxonomists to review the herpetofauna of the Garo Hills.

A New Species

In the present paper, we report the occurrence of the cricket subgenus Gryllitara Chopard, 1931 from India along with the description of a new species, Itara (Gryllitara) pilosa sp. nov., from the state of Kerala, South India. Suitable plates with close-up details have been presented to describe the new species, as well as for Itara (Itara) vietnamensis Gorochov being reported from North East India.

Based on material collected during the BIOICE project, the taxonomy and distribution of Terebellides (Polychaeta; Trichobranchidae) in Icelandic waters is presented. Terebellides stroemii Sars, 1853 and Terebellides gracilis Malm, 1874 (as Terebellides williamsae Jirkov, 1989) were previously reported from the area. Terebellides atlantis Williams, 1984 is reported for the first time after the original description and redescribed. Terebellides bigeniculatus sp. nov. is diagnosed by the presence of two thoracic chaetigers with geniculate chaetae. Terebellides williamsae Jirkov, 1989 is proposed as a junior synonym of T. gracilis, whose holotype is redescribed herein. Several body characters with high taxonomic value in Terebellides are reviewed under the SEM; additions to the diagnosis and new potential characters for a future taxonomic revision and phylogenetic study of the genus are also suggested. The geographical and bathymetric distribution of each species in relation to the GIF Ridge is discussed, and a key to Terebellides species from North East Atlantic waters is provided.

A New Species

The arctiine genus Alphaea Walker, 1855 is distributed in North and North East India, Nepal, southern China and northern Indochina. The genus was recently reviewed by Dubatolov & Kishida (2005). It is subdivided into three subgenera, Alphaea, Flavalphaea Dubatolov & Kishida, 2005 and Nayaca Moore, 1979 and includes 10 valid species. During a lepidopterological expedition to the north-western part of China’s Yunnan Province in May of 2018, an undetermined species of Alphaea was collected. The Chinese specimens have the wing pattern very similar to that of A. (Flavalphaea) khasiana (Rothschild, 1910), but red and black abdomen (that is orange and black in A. khasiana).

Aberrasine pangsau, sp. nov. is described as a new from Shergaon, Arunachal Pradesh, North East India. The new species is diagnosed with its closely similar species, A. strigivenata (Hampson, 1894). Additionally, we divide the genus into two species groups and provide the world checklist of the genus.

A New Species

The pinnotherid crab, Pinnothera obesa Dana, 1852, was originally described on the basis of material from Fiji, but its taxonomic status has long been obscure because the original description and figures are too brief and schematic by modern standards and the types are also lost. Examination of newly collected material from Fiji revealed the presence of two intertidal pinnotherid species assignable to the genus Arcotheres Manning, 1993, one of which is herein identified with Dana’s taxon. A neotype is designated for Arcotheres obesus n. comb. in the interest of nomenclatural stability, and a detailed redescription is given. Arcotheres obesus is morphologically similar to A. exiguus (Bürger, 1895) and A. rotundatus (Bürger, 1895), and differentiating characters are discussed. The species is also reported from Peninsular Malaysia. The second species is new to science, here described as Arcotheres ocularius, and is most similar to A. palaensis (Bürger, 1895) and A. arcophilus (Bürger, 1895). The new species is also recorded from Lombok, Indonesia. Arcotheres obesus and A. ocularius n. sp. are associated with bivalve mollusks of the genera Gafrarium spp. (Veneridae) and Anadara spp. (Arcidae), respectively.
