( Figs. 27–30 View FIGURES 27 – 30 )

Description. Male: Head: Eyes bare. Frons matt black slightly silver pollinose, frontal and interfrontal setulae short. Orbital plate shining black, bare apart from orbital seta. Lunule dark brown ground colour, lightly silver pollinose as are face and parafacials. Anterior genal setulae forming a single row along mouth margin. Antennae black, 1st flagellomere length to depth ratio 2:1. Arista with short plumosity; ratio of plumosity at maximum extent to depth of 1st flagellomere 0.25:1.

Thorax; mesonotum and scutellar disc shining emerald-green, anepisternum also shining green but katepisternum shining black with only faint green reflections. Anepisternum with 1 anterodorsal setae and 2 posterior setae. Katepisternum with 1 setae, a few scattered setulae anterior to it. One setae on both proepimeron and proepisternum. Scutellum may have lost some setulae but apparently with on margin 1 setulae on each side between lateral and apical setae, 0 between apical setae. Calypteres pale with whitish fringes. Wing slightly fumose, wing length 3.1 mm. Legs black, basal and second tarsomeres pale, apical tarsomeres darkened. Abdomen with a small rounded excision at apex.

Male terminalia: Epandrium; in lateral view 9th and 10th terga not completely fused, 9th terga a rather rectangular lobe attached to anterior surface of, and approximately half as wide as, 10th terga, 10th terga approximately 3x as wide as high, with a slight excavation on posterior surface, anterior margin narrowing towards ventral margin. Cerci elongated laminate structures, lying posterior to epandrium, in holotype the large cerci extending dorsally, but this most probably relates to the position in which the specimen dried. In posterior view the cerci form large, laminate processes with incurved margins, almost parallel on basal third, then slightly widening before slightly tapering to a broad rounded apex. Partly separated on apical third, medial margin with a row of 4 strong, curved setulae. Surstyli enclosed within shell of epandrium, rather rudimentary structures at the end of a narrow tendon connecting them basally to cerci, apically with a group of 4–5 long setulae. Phallus with broad basal section C-shaped, apical part with a right angled bend before terminating in a slightly flared apex.

Type material. Holotype ♂. ETHIOPIA; Shewa, Wendo, Genet , 2100m, 29.i.2000, A. Freidberg & I. Yarom, ( TAUI).

Only known from the Holotype.

Differential diagnosis. Another species with large, relatively simple cerci and rudimentary surstyli, phallus although sharply angled has no medial processes.

Etymology. the specific epithet refers to the location of capture of the Holotype.
