Abstract

A new species Hoplochaetella darwini sp. nov. is described from the Deccan Peninsula biogeographic zone of South Indian State, Tamil Nadu. The new species is distinguished from all known Hoplochaetella species by having only one pair of spermathecal pores in segment 7, and a combination of male and prostatic pores in segment 17. The canonical analysis of principal coordinates also supported the proposed new species, showing significant differences with other members of the genus based on the taxonomical characters such as the number and position of spermathecae and prostate glands. Furthermore, an identification key and updated checklist of known species in the genus are also presented along with updated locality details.
