Couri, Márcia & Pont, Adrian, 2016, Species of Coenosia Meigen (Diptera, Muscidae) described by Fritz van Emden from the British Museum Ruwenzori Expedition of 1934 – 1935, Zootaxa 4144 (4), pp. 529-555 : 552

Coenosia scutellaris ( Emden, 1940: 162)

( Figs 29–32 )

Holotype male seen ( Figs 29–32 ); mid right leg missing.

Diagnosis. General colour brown with grey pollinosity; scutum brown, grey pollinose with five narrow vittae, the median one reaching to middle of scutellum; palpus brown; legs yellow, apical fifth of mid and hind femora brown, tarsi brown; arista bare; scutellum almost bare and with only the basal pair of setae which are very long; anterior katepisternal hair-like; lower calypter about twice as long as the upper one; haltere yellow; legs long, especially fore tarsus and hind femur; fore tibia with a long median posterior seta; hind tibia with one median anterior, one anterodorsal inserted a little basad of it, and one subbasal posterodorsal seta; abdomen and wing long.

Notes. The species keys out as an isolated species in the group key and is very easy to recognize by the elongated shape of the body and wing, and by the presence of only the basal pair of setae on scutellum. Known only from the holotype male.
