Feuerborniella pilosella Cordeiro & Bravo   , sp. nov.

( Figs 21–27 View Figs 21–27 )

Type material. HOLOTYPE: ♁, BRAZIL: PARAÍBA: Areias, Brejo paraibano, 06°58 ′ S 39°44 ′ W, 567 m a.s.l., 25.–29. ix.2011, Nascimento, E. & Silva-Neto, A. Cols ( MZFS) GoogleMaps   . PARATYPES: 1 ♁, same data as holotype ( MZFS) GoogleMaps   ; 1 ♀, BRAZIL: PARAÍBA: Santa Terezinha , Faz. dos Franceses, 07°00 ′ 57.2 ″ S 37°24 ′ 29.8 ″ W 258 m a.s.l., 6.v.2011, Lima & Brito cols. ( MZFS) GoogleMaps   .

Diagnosis. Wing membrane pilose at veins and on midline between veins; hypoproct subquadrate posteriorly; pair of asymmetric conical parameres latero-ventral to aedeagus which are continuous basally with dorsal sheath to aedeagus.

Description. Head. Frons seta patch extending in thin stripe between eyes, reaching second row of facets on eye bridge ( Fig. 21 View Figs 21–27 ); eye bridge with 4 facet rows, separated by half facet diameter, vertex seta patch weakly continuous laterally with setae of posterior margin of eye ( Fig. 22 View Figs 21–27 ); 6–8 supraocular setae, 3–4 (1–2 in female) larger occipital alveoli; interocular suture present; clypeus wider than long with lateral row of 3 larger alveoli; frontoclypeal suture present; antenna with cylindrical scape, slightly longer than subspherical pedicel, flagellomeres apical to 8 th lost during preparation; ascoids Y-shaped; palpal formula 1.0: 1.4: 1.6: 1.9 ( Fig. 23 View Figs 21–27 ); labellum with 2–3 spines and 6 lateral setae.

Thorax ( Fig. 24 View Figs 21–27 ). Pre-sutural setae join supraalar setae; pteropleurite longer than wide, anterior margin shorter than posterior margin; long transverse suture on upper margin of katepisternum.

Wing ( Fig. 25 View Figs 21–27 ). Wing membrane pilose at veins and on midline between veins; second costal node absent; sc vein short, not extending beyond line of base of veins Rs, M and CuA1; R1 ending beyond level of CuA2; radial fork complete and apical to incomplete medial fork.

Legs. Distitarsi with apical projection.

Male terminalia. Epandrium subquadrate with concave posterior margin (almost V-shaped) and one small foramen; hypandrium narrow, separating proximate gonocoxites ( Fig. 27 View Figs 21–27 ); gonostylus slightly longer than gonocoxite, with several setae sparsely distributed throughout its length; gonocoxal bridge bilobed anteriorly; cercus conical, long, almost 2× length of epandrium ( Fig. 26 View Figs 21–27 ), with one apical tenacula and three subapical papillae, epiproct triangular; hypoproct subquadrate posteriorly; aedeagus asymmetric, aedeagal apodeme simple, short, less than half length of aedeagus; pair of asymmetric conical parameres latero-ventral to aedeagus, one shorter and the other longer, with truncate apex; one dorsal shaft to aedeagus, connected to one paramere by membrane ( Fig. 27 View Figs 21–27 ); base of parameres continuous dorsally to aedeagus; parameres articulating baso-dorsally with aedeagus and baso-ventrally with gonocoxal apodemes.

Female terminalia. Subgenital plate wider than long, bilobed posteriorly; ovipositor long, around 1.5 width of subgenital plate at base.

Differential diagnosis. This species is similar to F. paramuna   in the characteristic vestiture of the wing, asymmetric aedeagus, large subconical parameres and the presence of a dorsal shaft to aedeagus, but it can be differentiated from it by the asymmetrical parameres, and the subquadrate hypoproct.

Etymology. The species epithet is derived from Greek pilos, in allusion to the pilose wing; adjective.

Distribution. Brazil (Paraíba).
