New distributional records of fireflies (Coleoptera, Lampyridae, Luciolinae) from two Eastern States of India with notes on their biology and an updated Indian checklist

Abstract

The subfamily Luciolinae Lacordaire, 1857, a group of flashing fireflies, is composed of approximately 400 described species in the world. Though the taxonomy of this group has been fairly well established in Southeast (SE) Asia and the Australopacific Region, there is scope of gathering further information regarding taxonomic knowledge on this group from India. Until now, 32 Luciolinae species from nine genera have been reported from India, which is only about 8% (32 out of 400) of the world Luciolinae fauna. With this in mind, several faunistic surveys were conducted in Odisha and West Bengal States of India to explore the firefly fauna of the two States. The faunistic surveys conducted in the Odisha and West Bengal States of India have revealed six new distributional records of Luciolinae firefly species belonging to the genera Abscondita Ballantyne, Lambkin & Fu 2013, Asymmetricata Ballantyne 2009, Pteroptyx Olivier 1902 and Sclerotia Ballantyne 2016 in the two States, earlier which were recorded from other States of India. Of the already recorded species, Abs. perplexa is recorded for the first time from both the States, whereas Abs. chinensis, Asy. ovalis and Scl. aquatilis present new records for Odisha State and Pt. malaccae and Scl. substriata for West Bengal State. The newly-recorded taxa are presented with their examined materials, diagnoses and brief biological notes. Some more distinguishing characters were added for the male genitalia of Abs. perplexa and Asy. ovalis. Further, a checklist of Luciolinae firefly species already recorded from India is also presented.
