Phortica (Phortica) unispina sp. nov.

(Figs 23–26)

Type material. Holotype ɗ (MNHN): KENYA - labeled “Kakamega equatorial forest, 11.x.2002, S. Prigent”. Etymology. A combination of the Latin words: unus and spina, referring to the aedeagal median rod ending in a single spine.

Diagnosis. Aedeagal median rod nearly straight, pointed apically (Fig. 26); paramere apically slightly sclerotized, pointed, basally expanded (Fig. 26); vertical process of gonopods: right and left, lateral lobe each with a less sclerotized projections (Fig. 26).

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. 23). 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. 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. 24). Surstylus with numerous setae and approximately 11 small prensisetae on ventral margin to inner surface (Fig. 25). Paramere apically pointed, not knobbed, basally broadened, with 4 sensilla (Fig. 26). Vertical process of gonopods strongly sclerotized, asymmetrical bifurcated to lateral lobes, which connected to base of gonopods by a pair of rod-like bridges; right and left, lateral lobe each with three projections (Fig. 26). Aedeagal median rod single, strongly sclerotized (Fig. 26).
