Pseudosmittia fabioi sp. n., a new species from Sardinia (Diptera: Chironomidae, Orthocladiinae)

Abstract

A new species of Pseudosmittia Edwards 1932, P. fabioi, from Sardinia (Palearctic region), is described and figured as male and female. The generic diagnosis is emended based on characters found in the new species. The species is characterized by a triangular anal point with microtrichia at apex (not projecting beyond tergite IX), an inferior volsella characterized by a rounded lobe with a setose accessory lobe adpressed to the gonocoxite, a well developed tooth-like projection on the outer margin of the gonostylus, the lack of acrostichals and an antenna with 6 flagellomeres in female.
