Sobarocephala laticrinis spec. nov.

Figs 10, 48–50

Description (Fig. 10). Male. Body length 3.1–3.6mm. Arista densely plumose on basal third. Setae brown. Ocellar seta well-developed. Presutural intra-alar seta weak to well-developed. Two dorsocentral setae with slightly more developed setula in front of anterior dorsocentral. Acrostichal seta present. One lateral scutellar seta. Head yellow with infuscation at base of arista on first flagellomere (sometimes widened into large spot), ocellar tubercle brown, and gena, parafacial, occiput and face light yellow and pilose. Scutum usually brown with most of presutural region yellow; postpronotum sometimes brown. Scutellum and metanotum brown. Pleuron yellow with venter white and posterodorsal margin of anepisternum brownish. Legs yellow with coxae and base of femora white, fore tarsi and tibia brown, and hind tibia brownish. Knob of halter light brown. Wing clear, sometimes with anterior margin dusky. M1+2 ratio 3.0–3.7. Abdomen brown.

Female. As described for male except sometimes with pattern on scutum reduced to two pairs of strong central and faint lateral postsutural stripes.

Male terminalia. (Figs 48–50) Annulus well-developed, not enclosing 7th spiracle. Cerci small and rounded with setae short. Surstylus nearly as long as epandrium, subtriangular in profile but curved inwards, and with apex blunt and slightly angled posteriorly; numerous small tubercles clustered apically. Hypandrial arm thin medially and much longer than ventral lobe; ventral lobe narrow and slightly truncated, with one minute and two long distal setae. Phallapodeme, basiphallus and postgonite well-developed. Pregonite long and thin with two medial and two distal setae. Epiphallus large, lobate and as long as basiphallus. Distiphallus approximately 3/7 length of phallapodeme; paraphallus thin and spinulose with thumb short and broadly rounded.

Etymology. The specific name is derived from the Latin words for “side” and “hair”, referring to the presence of the presutural intra-alar seta.

Holotype: TANZANIA. Amani , 18.vii.1971, reared from rotten wood, N. Kolstrip (1♂, UMCZ).

Paratypes: TANZANIA. Same collection as holotype (2♀♀, UMCZ; 1♂ 2♀♀, DEBU), East Usambara, Amani , 1000m, H. Enghoff, O. Lomholt, O. Martin leg., 27.i.1977 (1♂, UMCZ), 8.ii.1977 (1♀, UMCZ), 1.ii.1977 (1♀, UMCZ), 7.ii.1977 (1♀, UMCZ), East Usambra Mts., Amani , 1000m, 10.vii.1980, M. Stoltze & N. Scharff leg. (1♂, UMCZ) [abdomen missing].

Comments. This species can be differentiated from other Old World Sobarocephala by having a brownish halter, a presutural intra-alar seta and a prescutellar acrostichal seta.
