Type material.

Holotype male. Tanzania: Tanga Region, West Usambara Mountains, Mazumbai Forest Reserve, "Loc G & F". 2-6.XI.1990 (Malaise trap), "ZMBs Tanzania Expedition" leg. [ZMBN].

Diagnosis.

Feuerborniella sinefurcata can be separated from all other Feuerborniella species by the following combination of characters: Wing forks incomplete, ejaculatory apodeme narrow, parameres separated, reaching apical ⅕ of aedeagus, aedeagus without subapical constriction.

Description.

Measurements in mm (n = 1). Wing length 1.50, width 0.63; head length 0.28, width 0.29; Antennal segments, scape: 0.06, pedicel: 0.04, flagellomere 1-3: 0.09; Palpomeres 1: 0.04, 2: 0.08, 3: 0.08, 4: 0.11.

Male. Holotype. Head about the same length as width, vertex about ⅓ of head length; eyes separated by approximately 1.5 facet diameters, eye bridge with 4 facet rows, interocular suture angular arch-shaped. Antennal scape about the same length as width, subquadrate; pedicel spherical, about the same length of scape, flagellomeres asymmetrical and nodiform, apical flagellomeres missing in revised material. Ascoids are absent in the revised material. Frontal alveoli patch undivided, anterior margin extending almost to interocular suture reaching the second facet; labella bulbous, setose, without teeth. Palpal segments sclerotised, palpal proportions 1.0:1.6:1.7:2.5.

Wing hyaline, except costal cell which is infuscated; wing length 2.6 times its width; Sc short ending at the base of R1; Radial fork apical to Medial fork, R2 not connected to R1, M2 not connected to M1; R5 looks more sclerotised than the rest of wing veins, ending at wing apex.

Terminalia. Hypandrium narrow, sclerotised, and plate-like; gonocoxites about half the length of gonostylus, cylindrical; gonostylus simple, tapering towards apex, incurved. Aedeagus extending towards the apex of gonostylus, parameres triangular-broad base, tapering towards the apex, weakly curved laterad, not connected by a bridge; ejaculatory apodeme narrow, about half the length of aedeagus. Epandrium about the same length as its width, with both anterior and posterior margins concave; surstylus cylindrical, slightly tapering towards the apex with a single spatulate tenaculum, about half the length of surstylus; Hypoproct with posterior margin rounded, tongue-shaped, covered in small setulae.

Etymology.

From Latin sine, meaning without and, furca, meaning fork - referring to the reduced radial and medial forks in the new species.

Remarks.

Feuerborniella sinefurcata sp. nov. is the 19th species of Psychodidae to be described from the West Usambara Mountains (see Kvifte (2022)) and the second Afrotropical species of Feuerborniella .
