Description. Body off white, heavily marked with dark brown (specimen preserved in ethanol before examination). Vertex with large brown patch apically at transition from vertex to face, with pair of brown patches medially, near to each other; tip of anteclypeus darkened. Pronotum with middle anterior margin and central part brown. Basal triangles of mesonotum dark. Forewing with inner margin of clavus darkened. ( Figs 27 View FIGURE 27 i–l)

Male abdominal apodemes 2S ( Fig. 27a View FIGURE 27 ) extended to middle of sternite IV.

Pygofer dorsal appendage ( Figs 27b, c View FIGURE 27 ) with apical part short, apex blunt; ventral appendage ( Figs 27b, d View FIGURE 27 ) very short, germ-like. Subgenital plate ( Figs 27b, f View FIGURE 27 ) with about 4 macrosetae. Style ( Fig. 27g View FIGURE 27 ) with pointed, tooth-like process extended form subapical inner edge of apical part, upper part of preapical lobe weakly sclerotized and serrated. Connective ( Fig. 27h View FIGURE 27 ) with manubrium wide and long, lateral arms thick and short. Aedeagus ( Figs 27i, j View FIGURE 27 ) with apical processes moderately long, extended away from shaft in caudal view; dorsal apodeme well developed, widened in caudal view.

Measurement. Male length 3.50mm.

Material examined. Holotype: ♂, UGANDA, Kibale National Park, Kanyawara, Makerere University Bio-logical Field Station , 1587m, 0º33.408'N, 30º22.603'E, 30.vii–05.viii.2005, Malaise trap, degraded mid-altitude Rainforest, coll. S.van Noort (IMC). GoogleMaps  

Etymology. The new specific epithet is derived from Latin adjective “ exiguus ” which means short, small, referring to the short pygofer ventral appendage.

Diagnosis. This species can be distinguished from the other species the genus by the shortened pygofer ventral appendage, presence of a tooth-like process on the style and by the well-developed dorsal apodeme.
