The tetrata species­group

This newly proposed species­group is established for the species characterised by four rows of multiple spermathecae in segments 12–15, and spermathecal pores in intersegmental furrows 12/13 13/14 14/15 15/16. To date no other known Tritogenia species is characterised in this way.
