Phortica (Phortica) vinywelea sp. nov.

( Figs 9–11 )

Type material. Holotype ɗ ( MNHN): KENYA - labeled “Kakamega equatorial forest, 11.x.2002, S. Prigent”. Etymology. From the Swahili word, meaning seta, referring to the fore tarsomere V with a long seta apically.

Diagnosis. Fore tarsomere V with 1 long seta (empodium ɗ, Fig. 13 ) apically; hind femur with 2 rows of slightness setae on antero- and posteroventral surface; aedeagal median rod strongly sclerotized, curved to Ushaped, with a pair of elongated projections apically ( Fig. 11 ); paramere curved lobe-shaped, slightly scerotized, lacking sensilla ( Fig. 11 ).

Description. Male: Eyes red-brown. Ocellar triangle black. Frons dark brown on upper 1/2, yellow brown on lower 1/2, with dense, thick setae medially. Fronto-orbital plate brown. Pedicel and first flagellomere almost yellow; arista plumose, not expanded apically. Face brown. Clypeus medially white-yellow, laterally brown. Gena and postgena brown. Palpus brown basally, grey-yellow distally. Thorax orange-yellow, with dark brown patches and pollinose pattern. Scutellum orange-yellow, brown at tip. Legs yellow except for fore femur brownish; mid femur with 1 row of slightness setae on basal part of anteroventral surface. Abdominal tergite I+II yellow, sublaterally with black patches; other tergites nearly entirely black. Sternites III to VI slightly longer than respective width. Male terminalia: Epandrium mid-dorsally constricted, laterally broadened, with dense setae ( Fig. 9 ). Surstylus with a few setae and approximately 12 prensisetae on ventral margin to inner surface ( Fig. 10 ). Vertical process of gonopods symmetrical, slightly sclerotized ( Fig. 11 ).
