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 : 534

Coenosia brunneigena Emden, 1940: 149 , stat. nov.

( Figs 62–64 )

Holotype male seen; in good condition.

Diagnosis. General colour brown with grey pollinosity; scutum with five brown vittae; face, parafacial and gena brown dusted; palpus dark brown; fore coxa yellow, mid and hind coxae grey pollinose; antennal insertion a little projecting; postpedicel long, about three times as long as pedicel; arista with short hairs; scutellum with both pairs of setae long, with setulae on disc; all katepisternals long and similar in size; lower calypter small and subtriangular, only slightly projecting beyond the upper one; haltere yellow; crossvein r-m more or less at the middle of the discal cell; fore tibia with no median seta; hind tibia with one median anterodorsal and one small posterodorsal; sternite 5 as in Fig. 62 .

Male terminalia. Cercal plate and surstylus as in Fig. 63 . Aedeagal complex as in Fig. 64 .

Notes. Originally described in Coenosia as a subspecies of C. heterocnemis Emden, 1940 and based on one male from Nyamgasani. In addition to the morphological characters mentioned by Emden (1940), the sternite 5, the length of the hypandrium and the shape of the aedeagus are very different from C. heterocnemis (see Figs 83–85 ), which led us to revise the status of this subspecies. The holotype was dissected and illustrated.
