Diagnosis
: Postocellar setae short; anterior portion of hypandrium expanded and curved dorsolaterally, distinctly broader than posterior portion; ventral epandrial lobe with 3 small apical spines; apex of aedeagus narrower than shaft in dorsoventral view, labiate, bulbous and deep in lateral view, bare of scales and spicules.
Description
: Coloration typical of group; epandrium (male) and cerci dark. Protarsal spines with standard array of fang-shaped 8 spines, 4 each on tarsomeres 1 and 2. Male genitalia: Ventral lobe of epandrium with 3 small spine-like setae at apex; surstylus with ~14 long prensisetae, including dorsal triad of 3 distinctively large ones; hypandrium uniquely expanded at anterior end, width 1.25x the posterior width.Aedeagus in dorsoventral view narrowed apically, not as wide as shaft; in lateral view thick and bulbous; aedeagus without spines, spicules or scales, completely bare. Female unknown.

Holotype
: Male, HS38, “Congo Belge [
Democratic Republic of the Congo
]: P.N.G., Miss H. De Saeger, II/ fd/17,
9-vi-1951
,
Réc. H. De Saeger
, 1888”. Minuten double-mounted, genitalia dissected by DG. In

.
Other Specimens
: Known only from the
type
specimen.
Etymology
: In reference to the distinctive, laterally expanded hypandrium.
Comments
: “P.N.G.” on the label appears to refer to Garamba National park, which borders
South Sudan
. H. De Saeger was an entomologist and secretary of national parks in the
Congo
, who led many collecting trips and long-term ecological studies in that park. The “II/fd/17” on the label apparently is a code referring to a park location.
