Zwick (1982a) noted the male “…Ceylonese members of this group, the testacea -group sensu stricto , are the most difficult species in the genus…” to distinguish. He further indicated that specimens of females with eggs are essential for species recognition in the group. All specimens of P. testacea and P. wedda (see below) in this sample were consistent in lacking a sternal brush on segment 8, and in having one on segment 7 ( Fig. 21 ), but the number of Rs veins, the details of the median patch of sensilla basiconica on tergum 9 and the aedeagal features varied, at least subtly, as detailed by Zwick (1982a) . It seemed probable, given the number of male specimens we examined from sites where female specimens of P. wedda dominate, that Zwick’s (1982a) indication, regarding the presence of sternal brushes on male abdominal segment 8 for Sri Lankan members of the testacea- group, might be in error. This has been confirmed now for small samples of P. limosa , P. srilanka , P. testacea and P. wedda (P. Zwick, pers. com., and our observations). Unfortunately, we have not had an opportunity to check this character for specimens of P. ceylonica , consequently we have not included this species in our revised key (below) to Sri Lankan and Indian Phanoperla males.
