New data on cockroaches of the subfamily Epilamprinae (Dictyoptera: Blaberidae) from India and Sri Lanka, with descriptions of new species and the genital complex of Aptera fusca (Thunberg, 1784).

New cockroach species from South India (Aptera brindlei sp.nov., Rhabdoblattella alexeevi sp.nov., R. euptera sp.nov., Morphna indica sp.nov.) and Sri Lanka (Placoblatta beybienkoi sp.nov., Morphna srilankensis sp.nov.) are described. The genus Rhabdoblattella Anisyutkin, 2000 is re-diagnosed. A revised key to the genera of Epilamprinae from South India and Sri Lanka and detailed morphological descriptions of new species are provided. The structure of the female genital complex of Aptera fusca (Thunberg, 1784) is described for the first time. Possible biogeographical connections of the cockroach fauna of Indian subcontinent and the phylogenetic significance of the right phallomere are briefly discussed.
