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
,
