Fulgenta pretoria sp. nov.

( Figs. 44–47 )

Description. Male: Head: Eyes bare. Frons black, dulled by microsculpture, frontal and interfrontal setulae very short. Orbital plate bare apart from orbital seta. Lunule with orange-brown ground colour, when seen from above covered with silver pollinosity as are parafacials and face. Anterior genal setulae in a single row along mouth margin. Antennae black, 1st flagellomere length to depth ratio 1.5:1. Arista very short haired; ratio of plumosity at maximum extent to depth of 1st flagellomere 0.25:1.

Thorax: mesonotum shining dark green. Anepisternum with 1 anterodorsal and 2 posterior setae. Katepisternum with 1 strong seta, numerous long black setulae on anterior part of sclerite, these approx.. 0.5x length of the seta. Scutellum shining green, margin with 3 short setulae on each side between lateral and apical setae, 0 between apical setae. Calypteres pale with whitish fringes. Wing clear, veins yellow, wing length 3.0mm. Legs black, basal and t2 of all legs clear yellow, apical tarsomeres darkened.

Abdomen; a small rounded excision at apex.

Male terminalia: Epandrium in lateral view with suture between 9th and 10th terga visible, 9th terga a rounded lobe, 10th terga twice as long as deep, elongated cerci lying posteriorly. In posterior view cerci expanding only slightly from base, almost parallel sided, on apical third curving gently inwards to apex where the two lobes are separated by a deep, narrow incision reaching almost half length of cerci, fused basally, centrally covered in numerous setulae with 2 parallel lines of longer setulae on basal half. Surstyli enclosed within shell of epandrium, a rudimentary rod-like structure connected by a tendon basally to cerci, bearing 4–5 long setulae. Phallus, basally thickened, apically with two almost right angled bends, bearing a pair of long, thin, pointed processes on medial surface.

Type material. Holotype ♂; SOUTH AFRICA; Rt. 27, 30 Km W. of Pretoria , 1.i.1995 , A. Freidberg, ( TAUI). Paratypes: SOUTH AFRICA; 1♂ with the same data as Holotype . KENYA; Gilgil , 1950m, 0°03’S, 5° 51’E, 22.ix.2005, A. Freidberg, 1♂ . Tangulbei , 30 Km NE Lake Baringo, 28.xi.1986 , A. Freidberg, 1♂. UGANDA ; Kasese, 10 Km S, 1500m, 7.i.1996, I. Yarom & A. Freidberg, 1♂, (all TAUI).

Differential diagnosis. This species is most similar to F. apicalis sp. nov but lacks the darkened apex of the wing, the cerci are broader and without apical processes; the phallus is more acutely angled, the apical portion being almost at 90 degrees to the basal, the internal spines are not so long and strong.

Etymology. The specific epithet refers to the area of capture of the Holotype.
