Taxonomic controversies in the Hydropsychidae

Conference paper

Abstract

The controversy featuring Hydropsyche instabilis (CURT.) and H. siltalai DÖHL. is outlined. The lectotype of H. instabilis, a female in the CURTIS Collection, has been re-examined and is considered to be distinct from H. siltalai. The male imago depicted by McLACHLAN as H. instabilis has been found in the British Museum (Natural History). Contrary to the view of DÖHLER, based on McLACHLAN’s drawing and subsequently accepted in the literature, this specimen is considered to be conspecific with MOSELY’s instabilis i.e. with H. siltalai and not with the female lectotype of H. instabilis. However the lectotype in the CURTIS collection has priority for the name H. instabilis.

SVENSSON & TJEDER’s claim that the designation by BOTOSANEANU & MARINKOVIC-GOSPODNETIĆ of a lectotype of H. siltalai DÖHL in the CURTIS Collection is invalid is upheld, but it is not agreed that their Swedish H. siltalai is conspecific with the female lectotype of H. instabilis or that TOBIAS had mixed the sexes of the two species. H. instabilis and H. siltalai should stand as discrete species. If the suggestion meets with approval, it is proposed to designate as lectotype of H. siltalai DÖHLER a male imago in the British Museum (Nat. Hist.) from which it is thought that KIMMINS’ drawings for MOSELY’s (1939) description were made.
