Helina emdeni Pont, 1980

( Figs 5–8 )

Examined type material: Lectotype male seen; mid right leg missing. One male from Kenya (Aberdare Range, Mt. Kinangop) dissected and illustrated.

Diagnosis. Male dichoptic; frons a little projecting in profile; dorsocentrals 1+3; fore tibia in male with a posterior seta and with long hairs curled at tips on basal half of ventral surface; hind tibia with two anterodorsal setae on middle third and one median posterodorsal; hind trochanter of male with a tuft of short black setulae; wing with brown spots on crossveins r–m and dm–cu; costal spine long.

Male terminalia. Sternite 5 longer than wide, with posterior membrane deep, with lobes robust, with long setae on external margin of posterior half ( Fig. 5 ); cercal plate and surstylus elongated; surstylus longer than cercal plate and with short setae on apical portion ( Fig. 6 ); aedeagal complex with hypandrium long and straight, epiphallus as long as postgonite; distiphallus short ( Figs 7–8 ).

Notes. This was a new name given by Pont (1980) to H. maculipennis Emden, 1941, a junior secondary homonym of Helina maculipennis ( Zetterstedt, 1845). It was originally described in Anthocoena Emden, 1941 , a genus of the “ Anthomyiinae ” (see also Emden 1951), because of the “almost complete sixth vein”.
