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

Abstract

A new species of <em>Pseudosmittia</em> Edwards 1932, <em>P. fabioi</em>, 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.
