1964. Chimarra nepalensis Kimmins, Bull. Brit. Mus. ( Nat . Hist.) Entomol., 15: 39.

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, 3♂♂, 1♀, Pathania, P.C. & Pandher, M.S. ( ZSI) .

Diagnosis: As per the observations of Kimmins (1964) in the original description of C. nepalensis , it is similar to the C. khasia Kimmins, 1957 . Further, C. nepalensis is similar to C. fenestrata Kimmins, 1964 and C. pupi Pandher & Saini, 2012 . It is more similar to C. fenestrata in the shape of male genitalia. But in C. nepalensis the membranous mesal lobes of tergum X are much extended, almost reaching beyond 2/3 of the sclerotized lateral lobes of tergum X whereas, the membranous mesal lobes of tergum X are short and reaching almost to the middle of the sclerotized lateral lobes of tergum X in C. fenestrata .

Distribution: Nepal and India (West Bengal).
