Phortica (Phortica) manjano sp. nov.

( Figs 6–8 )

Type material. Holotype ɗ ( MNHN): KENYA - labeled “Kakamega equatorial forest, 11.x.2002, S. Prigent”. Paratypes: 2ɗ, same data as the holotype except for 11–23.x.2002 (1ɗ in NMK; 1ɗ in SCAU).

Etymology. From the Swahili word, meaning yellow, referring to the yellow legs.

Diagnosis. Aedeagal median rod deeply bifurcated from base, slightly sclerotized ( Fig. 8 ); outer membranous tube with 4 sclerotized, furcated pieces per side ( Fig. 8 ).

Description. Male: Eyes red-brown. Ocellar triangle black. Frons brown, with 2 rows of thick setae submedially. Fronto-orbital plate brown. Pedicel and first flagellomere almost yellow; arista plumose, not expanded apically. Face brown on upper 1/2, yellow on lower 1/2. 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 brown, yellow on basal corners. Legs entirely yellow; fore tarsomere V lacking long setae apically. Abdominal tergites I+II yellow medially, with black patches sublaterally; the rest black. Sternites slightly longer than respective width, III and IV with long setae laterally. Male terminalia: Epandrium mid-dorsally constricted, laterally broadened, with dense setae ( Fig. 6 ). Surstylus with numerous setae and approximately 15 prensisetae on ventral margin of the inner surface ( Figs 6, 7 ). Hypandrium with 1 pair of lobe-like processes laterally ( Fig. 8 ). Vertical process of gonopods symmetrical, slightly sclerotized ( Fig. 8 ). Paramere slightly sclerotized, knobbed apically and with 9–10 sensilla basally Measurements.
