Phortica ( Ashima ) machoruka : Chen & Máca, 2012: 507 . Diagnosis. Aedeagal, median rod deeply bifurcated from base: ventral process strongly sclerotized, apically curved ventrad, but dorsal one less sclerotized, apically curved dorsad (“Fig. 21” in Chen & Máca 2012 ). Supplementary description (not repeating characters common to P . angulata ). Supracervical setae approximately 14. Arista with arb = 3–4/0; apical, leaf-like expansion narrower than 1/2 length, apically with long, awn-like projection. Cibarial, medial sensilla approximately 11 per side; posterior sensilla 5–6 per side. The antisymmetry is observed in the postgonites: in A-type, the left postgonite bears apically 1 long and 1 small, strongly sclerotized projections and 1 long, less sclerotized process, and subbasally 1 thick, apically blunt, strongly sclerotized projection, but the right one 2 long, strongly sclerotized projections and 1 long, less sclerotized process in the apical portion; but in B-type, vice versa (“Figs 21, 22” in Chen & Máca 2012 ). Specimens examined. Kenya : holotype ♂ (A-type), Kakamega Equatorial Forest , 11.x.2002 , S. Prigent leg. ( MNHN ); 1♂ paratype , ditto, except 11–23.x.2002 ( MNHN ) . Distribution. Kenya .
