A new frog species of the genus Microhyla (Anura, Microhylidae) is described from riparian mid-elevation (860 m asl) evergreen forest in Namdapha National Park, located in the eastern Himalayan state of Arunachal Pradesh, India. The new species can be morphologically distinguished from other congeners by a suite of characters such as adult size, dorsal and lateral colouration and markings, snout shape, foot webbing, and digit tip morphology. Phylogenetically, the new species is more closely related to some of the smallest known members of the genus. It forms a deeply divergent sister lineage to the clade containing members of the Microhyla zeylanica species group that are restricted to Peninsular India and Sri Lanka, and shows sequential relationship with Southeast Asian species M. superciliaris, followed by clade containing M. aurantiventris + M. butleri. The discovery indicates that novel taxa representing distinct evolutionary lineages still remain to be formally described in the genus Microhyla, especially from less explored regions such as the eastern Himalayan forests in Northeast India.

A New Species

Henckelia siangensis, a new species from Arunachal Pradesh of Northeast India, is described and illustrated here. The new species is remarkably different from all other allied species by its 5-winged calyx and elliptic-ovate calyx segments. It superficially resembles H. calva in glabrous stem and petioles, but differs from it in having persistent bracts, a campanulate 5-winged calyx and a style with glandular indumentum. A detailed morphological description, photographic illustration, and distribution of the new species are presented.

A new species similar to Bryocrumia vivicolor, the only known species in the genus Bryocrumia, is described as Bryocrumia malabarica spec. nova from the Malabar Wildlife Sanctuary in the Western Ghats of Kerala in Peninsular India. It resembles Homalia in external appearance and was collected in a rheophytic habitat along a stream channel in the evergreen forest. The new species is characterised by closely arranged leaves with distinct tricostate, ovate-rounded to truncate leaves, upper margin of leaf rounded with fine serrations and an inconspicuous central strand in stem cross section.

We describe Hedychiumziroensesp. nov. from Northeast India (NE India) which was discovered during one of our recent botanical explorations in Arunachal Pradesh. We provide detailed morphological comparison of this species with four other Hedychium species (H.griersonianum R.M.Sm., H.ellipticum Buch.-Ham. ex Sm., H.gomezianum Wall. and H.yunnanense Gagnep.), with which it shares some morphological similarities. The new species is characterised by a dense cylindrical spike, pubescent rachis, folded bracts, 2–3 flowers per cincinnus, deeply cleft labellum and a distinctive late monsoonal flowering phenology from August to September.

A New Species

A new species of the agamid genus Japalura is described, based on three specimens from Mizoram, northeast India. Japalura otai sp. nov. is most similar to J. planidorsata and J. sagittifera and can be distinguished from all congeners by the following combination of characters: adult size (SVL male 46.4 mm, female 52.2–58.7 mm), tail length/SVL ratio 160.5–187.5%, 10–11 supralabials, 9–12 infralabials, 45–47 middorsal scales, 17–20 lamellae under finger IV, 20–22 lamellae under toe IV, tympanum concealed, axillary fold present, nuchal crest, gular fold and gular pouch absent, enlarged keeled dorsal scales present, body shape subquadrangular in cross section. Japalura sagittifera is here redescribed, a lectotype and a paralectotype designated and photographs of the type specimens made available for the first time. All known localities for these three species are provided. The status of the genus Oriotiaris which was recently revalidated is discussed in detail and again synonymized within Japalura. The currently recognised polyphyletic Japalura is discussed in relation to morphological characteristics.
