On the taxonomy of genus Simplicia Guenée, with a new species from India (Lepidoptera: Erebidae: Herminiinae)

Herein, we describe one new species, Simplicia longivalva Raha & N. Singh, sp. nov. from Neora Valley National Park, Kalimpong District, West Bengal and report S. simplicissima Wileman & West, 1930, for the first time from India. Simplicia concisalis (Walker, [1866]) and S. moorei Swinhoe, 1919, having doubtful distribution in India, are reported here with confirmed distribution within the country. The genus Simplicia Guene is known by 13 species from India (including the new species and new record of this paper), of which, taxonomy of nine species is dealt herewith. The study also presents a first ever global checklist of Simplicia comprising 70 species (including the newly described species) along with their synonyms and distributional records. Detailed description of new species, diagnoses of all the studied species with close congeners along with their habitus and genitalia images and the distributional notes are provided.
