Material examined: India: West Bengal, Neora valley National Park, Suntalekhola Biodiversity Camp (W.B), 700 m, 27°00.789’N, 88°47.094’E, 27-ix-2018, 7♂♂, 2♀♀, Pathania & Pandher, (ZSI).
Additional material: Chimarra dibangensis: India: Arunachal Pradesh, Roing, 800m, 2-v-2010, 1♂, Pandher, M.S. and Parey, S.H. (NPC).
Chimarra reyangensis: India: West Bengal, Darjeeling, Reyang, F. R. H., 275 m; 25-iii-1973, 1♂, Sharma, H.S. & party (ZSI).
Diagnosis: The male genitalic structures of Chimarra biungulata in having well-developed postero-ventral process on sternum VIII, are similar to Chimarra exapia Malicky & Chantaramongkol, 1993b and C. atnia Malicky & Chantaramongkol, 1993b both reported from Thailand. But in in lateral view, inferior appendages are dorsally directed in C. biungulata and two sensilla one basal and another apical one are present on the lateral lobe of tergum X, whereas no such sensillae occurs in the related species. Furthermore, the substantial variances are evident in these species in the form of phallus, the number and shape of endothecal spines.
Distribution: Nepal and India (Arunachal Pradesh and West Bengal).
Remarks: Chimarra biungulata was described by Kimmins (1964) from Nepal, while Gosh & Chaudhary (1999) described a new species C. reyangensis from Darjeeling, West Bengal which seems to be an erroneous treatment. Similarly Pandher & Saini (2013) described C. dibangensis form Arunachal Pradesh and mistook it as a new species. The author happened to compare the types of C. reyangensis and C. dibangensis as well as freshly collected specimens from Neora Valley. All these agree in the morphological characters as well as in the shape of male genitalia with that of the C. biungulata. Hence, C. reyangensis Gosh & Chaudhary (1999) and C. dibangensis Pandher & Saini (2013) are hereby treated as synonym of C. biungulata.
