Kibalus Rousse, van Noort & Diller gen. n.

Diagnosis.

Head hemispherical, coarsely sculptured; mandible bidentate, upper tooth much longer than lower tooth; mesoscutum steeply elevated above pronotum; postpectal carina complete and strong; propodeum elongate, regularly rounded without differentiated horizontal anterior part in profile view; propodeal carination weak, more or less complete; fore wing with areolet closed; hind wing with distal abscissa of Cu1 absent; gastrocoelus long and shallow, thyridium indistinct; ovipositor very shortly projecting beyond metasomal apex.

Description.

Head. Hemispherical and coarsely sculptured; temple long and distinctly swollen behind eyes; vertex long and slightly convex behind ocelli; occipital carina complete; face subquadrate; clypeus separated from lower face by a deep groove, its ventral margin acute, rounded and finely serrate with blunt lateral protuberance; tentorial pit deep; mandible bidentate with upper tooth much longer than lower tooth, triangular and regularly narrowed to apex; malar line short to very short; palpi elongate; occipital and hypostomal carinae joined at mandibular base; flagellum long and slender, of female moderately flattened beyond middle, flagellum of male without tyloids.

Mesosoma. Slightly elongate, coarsely sculptured; epomia present and strong; mesoscutum strongly elevated above pronotum, regularly rounded in profile view; notaulus weak to absent; scutellum moderately convex, incompletely carinate laterally; sternaulus hardly discernible; epicnemial carina strongly raised ventrally and angled forward between fore coxae; postpectal carina ventrally complete and strong; propodeum moderately long, regularly rounded in profile view, without differentiated horizontal anterior part; carination more or less reduced, spiracle quite round. Wings. Fore wing with areolet pentagonal, closed, 3 Rs–m non–tubular and faintly pigmented; areolet receiving 2 m–cu at its middle; cu–a opposite Rs&M; hind wing with distal abscissa of Cu1 absent, 1/Cu& cu–a reclivous and slightly concave. Legs. Hind tibia irregularly shaped, its basal third more or less abruptly constricted; tarsal claws simple.

Metasoma. Tergite 1 slender, spiracle near apex, its basal section slightly higher than wide, regularly widened from middle to apex, polished; tergite 2 with gastrocoelus long and shallow, thyridium near mid–length of tergite, transverse and wide; hypopygium hiding base of ovipositor sheath; ovipositor shortly projecting beyond metasomal apex.

Etymology.

Named after the Kibale National Park where all specimens have been collected.

Distribution records.

Uganda.

Discussion.

The general habitus of Kibalus gen. n., the hemispherical head with long vertex, the junction of the hypostomal and occipital carinaeat the mandibular base and the complete postpectal carina suggest that it is related to Lusius Tosquinet, 1903, from which it differs mainly by the bidentate mandible, the closed areolet and the absence of elongate male genitalia.
