2012. Chimarra rifati Pandher & Saini, Zootaxa , 3478: 324

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

Diagnosis: In lateral view, the outline of segment IX and the inferior appendages with long hairs, this species resembles 3 Bhutanese species ( Chimarra semiramis Malicky 2007 , C. pontos Malicky 2007 , C. oreithyia Malicky 2007 ); 2 species from Thailand ( C. scopulifera Kimmins, 1957 , C. lahuorum Malicky & Chantramongkol, 1989 ), a Vietnamese species ( C. haimuoi Malicky 1995 ). But, in dorsal view of the male genitalia, it is closer to C. scopulifera . However, in C. rifati in lateral view, there is present a small postero-ventral process, lateral lobes of tergum X are curved postventrad, sclerotized as well as mesal lobes of tergum X are narrow and digitate (in dorsal view) whereas, in C. scopulifera posteroventral process is broad, sclerotized lateral lobes of tergum X are straight and directed posterad (in lateral view) and the mesal lobes of tergum X are broad at the base makes C. rifati a distinct species.

Distribution: India: (Sikkim and West Bengal).
