REMARKS: C. aridella has black antennae, yellow, rarely brownish palpi, and abdomen silver grey with light gold pollinosity and without spots in both sexes ( Coe, 1942; Collin, 1966; Beschovski & Tanasijtshuk, 1990; Beschovski, 1992). Rarely, however, faint dorsal spots on tergites 4-5 may be developed. The species is characterized by long setae on posterior margin of tergite 5 in both sexes, and the shape of tergite 9 of male which is oval in lateral view and shiny black ( Figs 9, 10 View FIGS 9-14 , 15 View FIGS 15-20 ). Aedeagus, in lateral view, variable at base, tending to be enlarged posteriorly, then characteristically and regularly curved from base to tip ( Figs 11 View FIGS 9-14 - 20 View FIGS 15-20 ), fairly elongated, but always longer than parameres. Ventral part of tubular aedeagus less sclerotized and ruffled, and therefore warps sometimes during preparation for morphological study; thus a similar shape may appear very different ( Figs 11, 13 View FIGS 9-14 , 16, 18, 19 View FIGS 15-20 ) and may be source for misidentifications. The species is common in Italy from 600 to 2000m.
