Fig. 2A

Etymology: Named after the type locality of Lake Baringo, Kenya.

Description:

Head: Dark red-brown to black, dull silver-gold and silver pruinose, pale yellow and red-brown setose.Antenna: Red-brown except for yellow proximal ends of postpedicel and style. Segmental ratios: 1:1.0:3.0:2.2 (scape, pedicel, postpedicel, style). Scape and pedicel of similar development, but pedicel broader, pale yellow setose. Postpedicel laterally compressed, parallel sided, broadly rounded distally. Style narrower than distal end of postpedicel, equipped with long brown setae projecting from all surfaces. Face and frons dull silver-gold pruinose, vertex dull gold-silver pruinose, mystax pale yellow, ocellar macrosetae short red-brown. Occiput uniformly dull gold-silver pruinose (See Fig. 2A), red-brown setose dorsally, yellow-white ventrally. Face to head width ratio in anterior view 1: 3.7 (face narrower than one eye). Proboscis dark red-brown, straight, pale yellow setose. Palpi minute, 2-segmented, pale yellow setose.

Thorax: Dark red-brown to black, extensively silver-gold and silver pruinose, pale yellow setose. Mesonotum: Extensively pruinose with following apruinose areas: postpronotal lobes (partly), extensive lateral areas anterior to transverse suture and postsuture that extend posteriorly to hind margin and involve postalar lobe, pair broad medial stripes that extend narrowly anteriorly but do not reach anterior margin as well as posteriorly where they coalesce before reaching posterior margin. 2 brown-yellow npl (other macrosetae weakly developed), general setae pale yellow. Scutellum dark red-brown, largely apruinose except for small anterolateral silver pruinose areas, fine yellowish setose (apical macrosetae poorly differentiated). Pleura fairly uniformly silver pruinose. Katatergal setae pale yellow. Legs: Coxae dark red-brown, silver pruinose, whitish setose. Trochanters dark red-brown, pale yellow-white setose. Femora dark red-brown with brown-yellow proximal and distal ends, mixed dark red-brown and pale yellowish setose. Tibiae brown-yellow with red-brown distal ends, mixed dark red-brown and yellow setose.Tarsi brown-yellow, mostly dark red-brown setose. Wings: 3.0 × 1.1 mm (holotype). Veins yellow to brown-yellow. Membrane transparent, unstained, entirely lacking microtrichia. Abdomen: Terga dark red-brown to black, largely apruinose except for silver pruinose anterolateral margins, white setose. Sterna dark red-brown, extensively gold-silver pruinose except for large posterolateral corners, white setose. ♀ genitalia dark red-brown (♂ unknown).

Holotype: KENYA: 1♀ ‘ Kenya Kampi-Va- / Samaki ( Lake Baringo) / 00°37’N: 36°02'E 980 m / 30.v.–2. vi.1980 / B. Lamoral Malaise’ ( NMSA).

Paratypes: 2♀ same data as holotype .

Distribution ( Table 1), phenology (Table 2) and biology: Known only from the type locality. Collected in a Malaise trap at the end of May and early June in an equatorial situation. The locality is dominated by open woodland and savanna.
