Phortica (Phortica) machoruka sp. nov.

(Figs 18–22)

Type material. Holotype ɗ (MNHN): KENYA - labeled “Kakamega equatorial forest, 11.x.2002, S. Prigent”. Paratypes: 7ɗ, same data as the holotype except for 11–23.x.2002 (2ɗ in MNHN; 2ɗ in NMK; 3ɗ in SCAU).

Etymology. A combination of the Swahili words: macho and ruka, meaning eye flies, referring to the fly habit that usually flying around human eyes.

Diagnosis. Aedeagal median rod deeply bifurcated from subbasally: ventral one longer, strongly sclerotized, curved apically (Fig. 21); dorsal one slender, almost membranous, straight (Fig. 21); vertical process of gonopods: right, lateral lobe submedially with a strong projection, left, lateral lobe submedially with a small triangular projection (Figs 21, 22).

Description. Male: Eyes brown-red. Ocellar triangle black. Frons brown, with 2 rows of thick dense setae. Fronto-orbital plate yellow-brown. Pedicel and first flagellomere almost grey-yellow; arista plumose, expanded apically, without ventral branches (Fig. 18). Face yellow-brown on upper 1/2, dark brown on lower 1/2. Clypeus medially white-yellow, laterally black. Gena and postgena brown to dark brown. Palpus brown basally, grey-yellow distally. Thorax and scutellum orange-brown, with black patches and pollinose pattern. Legs yellow except for fore femur brownish; fore tarsomere V with 1 long seta apically (slightly shorter in three paratypes). Abdominal tergites I+II yellow, the rest brown. Sternites III to VI slightly longer than respective width. Male terminalia: Epandrium mid-dorsally constricted, laterally broadened, triangularly protruded on ventral margin, with dense setae (Fig. 19). Surstylus with numerous setae and approximately 11 prensisetae on ventral margin to inner surface (Fig. 20). Paramere apically slightly pointed, not knobbed, basally with 7 sensilla (Fig. 21). Vertical process of gonopods strongly sclerotized, deeply asymmetrically bifurcated to lateral lobes, which connected to base of gonopods by a pair of rod-like bridges; right and left, lateral lobe each with four projections (Figs 21, 22).
