Feuerborniella jezeki Cordeiro & Bravo , sp. nov.

( Figs 7–13 )

Type material. HOLOTYPE: ♁, BRAZIL: BAHIA: Pindobaçú , 10°39 ′ S 40°21 ′ W, 26.ix. 2009, 500 m a.s.l., light trap, F. Bravo col. ( MZFS).

Diagnosis. Dorsal extension of frons seta patch not reaching eye bridge; scape of about same length of pedicel, flagellomeres 11–13 fused together; subapical enlargement on veins R 2 and M 3, infuscation on veins R 5, CuA 1 and basal half of CuA 2; cerci short, not longer than epandrium, with two tenacula; gonocoxal bridge W-shaped.

Description. Male. Head. Frons seta patch slightly divided basally but extending upwards in thin stripe, not reaching eye bridge ( Fig. 7 ); eye bridge with 4 facet rows, separated by half facet diameter, vertex seta patch continuous laterally with setae of posterior margin of eye ( Fig. 8 ); 8 supraocular setae, 1 larger occipital alveolus; interocular suture present with short dorsal extension; clypeus wider than long with lateral row of 4 larger alveoli; frontoclypeal suture present; antenna with cylindrical scape, about same length as subspherical pedicel, and apparently 14 flagellomeres (terminal flagellomere probably lost during preparation), 12 and 13 reduced, 11, 12 and 13 fused together ( Fig. 9 ); ascoids Y-shaped; palpal formula 1.0: 1.8: 1.8: 1.9 ( Fig. 10 ); labellum with 3 spines and 3 lateral setae.

Thorax ( Fig. 11 ). Presutural setae join supraalar setae; pteropleutite longer than wide, anterior margin around 1.5× shorter than posterior margin; long and complete transverse suture on upper margin of katepisternum.

Wing membrane bare except on veins; second costal node absent; sc vein short; radial fork complete and apical to incomplete medial fork; subapical enlargement of vein M 3; costal cell slightly darkened.

Legs. Distitarsi with apical projection.

Male terminalia. Epandrium subquadrate with concave posterior margin and one small foramen; hypandrium narrow, separating gonocoxites ( Fig. 13 ); gonostylus about length of gonocoxite, with group of setae on external side of base of gonocoxite and several setae sparsely distributed throughout its length with one longer seta at apex; gonocoxal apodemes meet medially to form W-shaped gonocoxal bridge; cercus about same length as epandrium, with two apical tenacula and two subapical papillae ( Fig. 12 ); epiproct not projecting posteriorly; hypoproct simple; aedeagus symmetrical, aedeagal apodeme simple and short, around 1/3 length of aedeagus; pair of conical parameres latero-ventral to aedeagus, with apex slightly pointing to outer side ( Fig. 13 ); parameres are continuous with large stripe dorsal to aedeagus, forming aedeagal ‘ring’; parameres articulated basally with base of aedeagus and gonocoxal apodemes.

Female. Unknown.

Differential diagnosis. Wing is not illustrated as both wings are damaged on holotype, but the described characteristics can be seen on the parts of wings mounted on the slide. F. jezeki is very similar to F. opposita but it can be separated from it by the shape of aedeagus, which is spatulate in the new species and very narrow and rod-like on F. opposita .

Etymology. The species epithet is given in honor of Dr. Jan Ježek for his enormous contribution to the taxonomy of the family Psychodidae .

Distribution. Brazil (Bahia).
