( Figs 59–61 )

Holotype male seen; in good condition.

Diagnosis. General colour brown with grey pollinosity; head round with faint yellow golden pollen under certain lights; antenna short, apex far from mouth-margin; palpus and proboscis shining brown; antenna dark brown with apex of pedicel strongly grey pollinose and contrasting with general colour of antenna; legs yellow contrasting with the body colour; coxae grey dusted; scutum with three brown vittae, the median reaching apex of scutellum and the lateral ones faint; scutellum with both basal and apical setae long; all katepisternals long and similar in length; hind tibia with only the anterodorsal seta in male, the female also with an anteroventral seta; sternite 5 as in Fig. 59 .

Male terminalia. Cercal plate and surstylus as in Fig. 60 . Aedeagal complex as in Fig. 61 .

Notes. The species was described in the genus Coenosia and can be easily recognized by the yellow legs and by the absence in the male of a submedian posterodorsal and anteroventral seta on hind tibia. One male (not a paratype) was dissected and illustrated.
