Nsesa Dworakowska, 1974: 233

Type species: Nsesa matteba Dworakowska, 1974 , by original designation

Description. Body large and robust, body length of most species arranges from 5.0 to 6.0 mm. Head slightly narrower than pronotum, crown fore margin subparallel to hind margin, coronal suture distinct. Ocelli rudimentary with elongated, crescent-shaped vestiges. Face convex in profile. Pronotum with lateral margins divergent posteriorly in dorsal view, hind margin almost straight. Forewing ( Fig. 21a ) with first and third apical cell wide, second and fourth apical cell narrow, fourth cell not extended to tip of wing, shorter than third. Hind wing ( Fig. 21b ) with or without RA.

Male abdominal apodemes 2S very small, not extended to hind margin of sternite III. Anal tube short, membranous, without appendages.

Male genital capsule cylindrical, sclerotized. Pygofer lobe long, with some small setae dorsally near base, with row of rigid microsetae on distal angle and near ventral margin on inner membrane; dorsal appendage fused to lobe basally, small to large; ventral appendage absent. Subgenital plate narrow and long, surpassing hind margin of pygofer side, rounded and pigmented distally, macrosetae absent to many, with row of fine setae along outer margin and numerous microsetae scattered on distal disc. Style with apical part greatly elongated, thin, preapical lobe indistinct. Connective completely fused to aedeagus, usually without central lobe. Aedeagal shaft tubular, curved dorsad, usually with asymmetric processes apically; dorsal apodeme short to long; preatrium rudimentary; gonopore usually terminal.

Distribution. Republic of Congo; Cameroon.

Remarks. This is a new record for Cameroon.

Diagnosis. This genus is similar to Szymczakowskia Dworakowska, 1974 , but the pygofer lobe lacks the sclerotized inner plica and has numerous microsetae near ventral margin, the style is elongate and thin, and the connective is fused with the aedeagus.
