(Figs 14–20)
Type material. HOLOTYPE: ♁, BRAZIL: BAHIA: Senhor do Bonfim, 24.i.2006, Vieira R. & Chagas C. cols (MZFS)
Diagnosis. Eyes separated by 4 facet diameters; costal cell and veins R 1, R 5, CuA 1 and CuA 2 darkened; cerci with three apical tenacula; aedeagus symmetric, spoon-shaped; pair of subconical parameres, with curved and acute apex.
Description. Male. Head. Frons seta patch extending to superior margin of eye bridge; eye bridge with four facet rows, separated by 4.0 facet diameter (Fig. 14); vertex seta patch continuous laterally with setae of posterior margin of eye (Fig. 15); supraocular setae forming two irregular antero-lateral rows and apparently 2 larger occipital alveoli can be seen in posterior view, but they look continuous with supraocular setae; interocular suture present; clypeus wider than long with row of 3 larger lateral alveoli; frontoclypeal suture present; antenna with cylindrical scape slightly longer than spherical pedicel (Fig. 14), flagellomeres beyond 7 lost during preparation; ascoids Y-shaped; palp segment 1 with sensory organ, palpal formula 1.0: 1.4: 1.4: 1.7 (Fig. 16). Labellum compact, slightly fleshy, with three spines on inner margin and three lateral setae.
Thorax (Fig. 17). Pre-sutural setae join supraalar setae; pteropleutite longer than wide; long transverse suture on upper margin of katepisternum.
Wing (Fig. 18). Wing membrane bare except on veins; second costal node absent; Sc vein short ending before base of R 1; R 1 ending beyond level of CuA 2; radial fork complete and apical to incomplete medial fork; costal cell and veins R 1, R 5, CuA 1 and CuA 2 darkened; basal half of CuA
2
enlarged.
Legs short in comparison to body length, distitarsi with short apical projection.
Male terminalia. Epandrium subquadrate with one large foramen; hypandrium narrow, separating gonocoxites (Fig. 20); gonostylus about same length as gonocoxites, with acute apex, group of setae on external side of base and several small setae sparsely distributed on internal side throughout its length; gonocoxal bridge subquadrate anteriorly, pilose and bilobed posteriorly; cercus around same length as epandrium, wider on basal 2/3, with 3 apical tenacula (around 0.4× length of cercus) and 3 subapical papillae (Fig. 19); epiproct not projecting posteriorly; hypoproct wider than long; aedeagus symmetric, spoon-shaped; aedeagal apodeme simple, around half length of aedeagus; pair of subconical parameres lateral to aedeagus, with slightly curved and acute apex (Fig. 20); the parameres are continuous with stripe dorsal to aedeagus, forming aedeagal sheath; ventrally base of parameres articulated with base of aedeagus.
Female. Unknown.
Comments. The spatulate aedeagus and the symmetrical simple, slightly curved and medially joined parameres are typical for Feuerborniella, but the antennal apex of this species is unfortunately unknown. This species has three tenacula as in F. pollicaris, but can be differentiated from it by the distance of eyes and the shape of gonostylus.
Etymology. The species epithet is derived from the Latin concavus, adjective, in allusion to the spoon-like format of aedeagus.
Distribution. Brazil (Bahia).
