Camarota ugandae   sp. nov.

( Figs. 3 View FIGURES 1–4 , 6, 9, 11, 14 View FIGURES 5–14 , 18 View FIGURES 15–19 )

Diagnosis. Ocellar triangle brown, vein R 2+3 touches R 1 throughout, hypandrium wide and postgonite longer than pregonite.

Material examined. Holotype ♂ Uganda, Kabarole distr., swampy valley 8 km SSE Fort Portal , 0°29’49”N, 30°19’57”E, 1340 m, 17.iii.2012, sweeping, M. von Tschirnhaus leg. [ MZUSP] (genitalia and left wing dissected) GoogleMaps   . Paratypes 2 ♀ same data [ ZSM] GoogleMaps   ; 1 ♂ Uganda, Queen Elisabeth National Park , 1100–1200 m, 15.vii.1994, sweeping, Oliver Krüger leg. [ MZUSP] (genitalia and both wings dissected)   .

Description. Body length, 2.15 mm. Wing length 1.98 mm. Background color pale yellow. Head ( Figs. 3 View FIGURES 1–4 , 6 View FIGURES 5–14 ). Slightly broader than thorax, as broad as long and as long as the scutum dorsally, 1.5 times longer than deep in profile; the polished light brown ocellar triangle extending to anterior margin of frons, ill–defined, longitudinal groove absent; frons projecting; occiput and postgena light brown; gena broader at the base than at the anterior end; the sclerotized vibrissal angle less prominent than in C. curvipennis   ; parafacialia not visible in profile; eye with small, sparse pilosity, long axis horizontal; facial carina acute, incomplete; clypeus darkened; labellum with three pseudotracheae each side; palpus cylindric; pedicel short; first flagellomere trapezoid, yellow with a brownish apex, sensorial pit absent; arista slightly enlarged at base and flattened in its whole length (but less widened than in C. curvipennis   ), yellow, with short and sparse pubescence. Chaetotaxy: numerous short proclinate fronto–orbitals; interfrontals and postocellars tiny and widely separated, inner and outer verticals developed; ocellars proclinate, divergent, very small; vibrissa indistinct; gena with few pale hairs. Thorax ( Fig. 3 View FIGURES 1–4 , 9 View FIGURES 5–14 ). Light brown; scutum length/ width ratio 1.25, light brown, with five almost indistinct orange colored stripes, the central one abbreviated in front of scutellum, coarse and punctured, flattened dorsally, with small sparse pilosity; scutellum coarse, rounded apically, flattened, with the pair of apical seta long, upright and convergent, both widely separated from each other, inserted dorsally in the middle of the disc. Posterior to the “apical” setae (in subapical position) the scutellum is bare; pleuron polished; anepisternum pilose; katepisternum with some few hairs; postpronotal seta weakened; anterior notopleural seta weakened; 2 posterior notopleurals well–developed; 1 dorsocentral, an anterior postalar; halter pale with knob brownish. Legs. Legs yellow, tibial organ narrow; all claws symmetrical. Wing ( Figs. 11, 14 View FIGURES 5–14 ). Wing in distal third bent around abdomen and not exceeding the tip of epandrium. Membrane hyaline; costal sectors 1–2–3–4 as 18–9–15–1; veins weakly sclerotized; R 4+5 strongly concave anteriorly, reaching the costa before wing apex; R 2+3 touches R 1; R 4+5 and M 1 divergent; distance between r–m and dm–m 3 times r–m length; similar to C. curvipennis   between M 1 and M 4 a “vena spuria”–like fold present; anal lobe slightly reduced.

Abdomen. Five light brown sclerotized tergites. Male terminalia ( Fig. 18 View FIGURES 15–19 ). Epandrium well developed; mesolobus (fused cerci) wide, trapezoidal; bacilliform sclerite wide, placed under the mesolobus; surstylus conical, not divided, fused to the epandrium at base; hypandrium thickened, arms long, apex with internal projections large; gonites aligned longitudinally; pregonite short; postgonite long, with 2 pairs of setae and sensorial pores; basiphallus long, bifid apically; distiphallus short; phallapodemic sclerite developed, with a flap; phallapodeme short, bifid at posterior half; epiphallus well defined, sclerotized. Female terminalia. Unknown.

Etymology. The specific epithet ugandae   is due to the country where the specimens were collected.

Comments. All Camarota   species have a lanceolate arista ( Deeming, 1981). However, the arista of C. ugandae   is slightly narrower than in the other Afrotropical species. As the specimens were stored in ethanol for some years, they may have bleached out, modifying the coloration tone.
