The subgenus <i>Dasymolophilus</i> of the genus <i>Tasiocera</i> from the Western Palaearctic with the description of a new species (Diptera: Limoniidae: Chioneinae)

In this paper, we describe a new species of Tasiocera of the subgenus Dasymolophilus, collected in southern Italy. This discovery brings the number of Western Palaearctic Dasymolophilus species to nine. In addition, we compile taxonomic information on the known species. We provide an identification key based primarily on male genitalia, avoiding the use of macrotrichia patterns on the wing membrane as a distinguishing feature due to the difficulty of assessing this character. Tasiocera are among the smallest crane flies, and little is known about their biology. Where data are available, we include brief information on the species’ biology and ecology. Additionally, we present the known distribution based on data from the Catalogue of the Craneflies of the World.
