Feuerborniella pollicaris ( Quate, 1996 )

comb. nov.

Feuerborniella pollicaris ( Quate, 1996)   comb. nov.

( Figs 1–6 View Figs 1–6 ) Material examined. 1♁ ( MZFS): BRAZIL: BAHIA: Senhor do Bonfim, Serra de Santana , 24.ix.2009, F.Bravo col.   ; 1 ♁ ( MZFS): BRAZIL: CEARÁ: Parque Nacional Ubajara , 3°50 ʹ 21.2 ʺ S 40°54 ʹ ’6.7 ʺ W, 22–29.x.2011, E. Nascimento and A.M. Silva-Neto cols. The holotype was also examined   .

Diagnosis. Antenna with scape of about same length of pedicel and 14 flagellomeres, 11–13 fused, 14 separated; seta patch of anepisternum strongly reniform; cerci with three tenacula; gonostylus with apex bifid; aedeagus asymmetrical; parameres paired, horn-shaped.

Additional characters. Male. Head ( Fig. 1 View Figs 1–6 ): vertex seta patch continuous laterally with setae of posterior margin of eye ( Fig. 2 View Figs 1–6 ); 7–9 supraocular setae (5 on specimen from Ceará), 4–5 larger occipital alveoli; clypeus wider than long with a lateral row of 6–8 larger alveoli; frontoclypeal suture absent; antenna with scape cylindrical, as long as subspherical pedicel; labellum with three spines and 7 lateral setae. Thorax ( Fig. 3 View Figs 1–6 ): pre-sutural setae very close to supraalar setae but clearly separated in the holotype; seta patch of anepisternum strongly reniform; pteropleurite longer than wide, anterior margin around 2× shorter than posterior margin; long but incomplete transverse suture on upper margin of katepisternum. Wing ( Fig. 4 View Figs 1–6 ): wing membrane bare except on veins; second costal node absent; vein sc short, not extending beyond line of bases of veins Rs, M and CuA1; R1 ending beyond level of CuA2; radial fork incomplete (complete on specimen from Bahia) and apical to incomplete medial fork. Legs: distitarsi with apical projection. Male terminalia: Epandrium subquadrate with one small foramen; hypandrium micropilose, separating gonocoxites ( Fig. 6 View Figs 1–6 ); gonocoxites with seta patch on outer margin and two isolated setae on inner margin; gonostylus with apex bifid, slightly longer than gonocoxite, with group of setae on external side of base and several setae sparsely distributed throughout its length, with subapical larger sinuous setiform sensillum; gonocoxal bridge bilobed anteriorly and not expanded posteriorly; cercus conical ( Fig. 5 View Figs 1–6 ), about same length of epandrium, with one apical and two subapical tenacula and three subapical papilla. Apical tenaculum is slightly longer than other two, all tenacula around half length of cercus; epiproct nearly triangular; hypoproct ellipsoid, almost 2× wider than long; aedeagus asymmetrical, aedeagal apodeme simple, around half length of aedeagus; pair of sinuous parameres lateral to aedeagus, with conspicuously curved apex ( Fig. 6 View Figs 1–6 ); parameres are continuous dorsal to aedeagus.

Female. Unknown.

Differential diagnosis. This species is similar to F. uncinata   and F. opposita   in the shape of parameres and appearance of eye bridge, but it can be easily separated from them by the bifid gonostylus and number of tenacula, although QUATE (1955) says that F. opposita   may rarely have three tenacula.

Distribution. Costa Rica ( QUATE 1996), Brazil (Bahia, Ceará) (new records).
