Coenosia kilembana (Emden, 1940: 216)

(Figs 104–106, as C. rebmanni) (junior synonym of C. rebmanni Speiser, 1924, syn. nov.)

Holotype male seen; in good condition.

Diagnosis. General colour brown with grey pollinosity; scutum brown; postpronotum and pleura grey dusted; frons dark, fronto-orbital plate weakly grey pollinose; face, parafacial and gena silver from certain angles; palpus light brown; fore coxa yellow or partially infuscated, mid and hind coxae partially grey pollinose; femora yellow on basal two-thirds, remainder of legs brown; the narrowest point of the fronto-facial stripe below the base of the antenna; antennae inserted at dorsal third of eye; postpedicel long, about six times the length of pedicel; arista short-haired, bare on apical third; scutellum with both pairs of setae present and long, with setulae on disc; anterior and lower katepisternals about two-thirds the length of the long posterior seta; haltere yellow; lower calypter about 2.5 times as long as upper one; fore tibia with a very long posteroventral seta; hind tarsomeres 1–3 moderately to distinctly compressed; hind tibia with one anterior and one long anterodorsal inserted at almost the same level, the anterior one much shorter; sternite 5 as in Fig. 104.

Male terminalia. Cercal plate and surstylus as in Fig. 105. Aedeagal complex as in Fig. 106.

Notes. Included in the rebmanni group. Emden (1940) stated that there are probably only two valid species in this “group”— C. translucida (Emden, 1940) and C. rebmanni – and that the other species are probably subspecies of C. rebmanni . Pont (1980) considered this species as a subspecies of C. rebmanni . We dissected a male paratype of C. kilembana and a male of C. rebmanni and the terminalia are exactly the same. On the other hand, other species of this group that we dissected ( C. ciliventris and C. translucida) have very characteristic terminalia. We are proposing the new synonymy of C. kilembana with C. rebmanni, syn. nov.
