Bryopharsos paulistensis sp. nov.

( Figs. 13–24 View FIGURES 13–24 )

Type material. Holotype, male: BRAZIL, São Paulo, Sete Barras , 13–27.XI.2004, Malaise trap, without name of collector ( MZFS). 6 paratypes male with same data of holotype except by date of collect: 1 paratype 25.VII– 7.XI.2004; 2 paratypes 16–30.X.2004; 3 paratypes 24.XII.2004 – 08.I.2005 ( MZFS).

Etymology. The specific name paulistensis is based on the State where the specimen of the new species was collected, namely São Paulo.

Diagnosis. Male. Eye bridge with five facet rows; wing twice as long than as wide; ejaculatory apodeme subrectangular in dorsal view; cercus narrower in the one-half apical portion, with one tenaculum; aedeagus long, expanded, hemispheric basally and narrow apically with pointed apex.

Description. Male. Head vertex length almost twice the width of eye bridge; eye bridge with five facet rows; pedicel shorter than scape ( Figs. 13 and 16 View FIGURES 13–24 ). Occipital setae present and distributed into one basal block; post-ocular alveoli absent ( Fig. 14 View FIGURES 13–24 ). Labellum very short, ending before the apex of labrum; maxillary lacinia short, knife like well sclerotized ( Fig. 15 View FIGURES 13–24 ). Fourteen flagellomeres, eccentric except first flagellomere that is spherical; internodes of flagellomeres 1–4 short; internodes of flagellomeres 4–13 0.7 times the length of nodes; flagellomere 14 without internode ( Figs. 16 and 17 View FIGURES 13–24 ). One pair of ascoids per flagellomere, leaf shaped ( Fig. 18 View FIGURES 13–24 ). Thorax without allurement organs. Wing twice as long as wide; seta alveoli distributed uniformly on wing membrane ( Fig. 19 View FIGURES 13–24 ). Hypandrium narrow; gonostylus with blunt apex; aedeagus expanded, hemispheric basally and narrow apically with pointed apex; ejaculatory apodeme rectangular in dorsal view; paramere with the same length of aedeagus and capitate apex ( Figs. 20 and 21 View FIGURES 13–24 ). Gonocoxal apodeme anteriorly projected as two thin blades ending in an acute apex, not fused, and posteriorly projected as a pair of lateral, ovoid lobes with long bristles ( Fig. 20 View FIGURES 13–24 ). Epandrium with posterior margin slightly concave; cercus with apical one half narrower than base with one apical tenaculum (holotype with right cercus with two tenacula); subepandrial sclerite plate-like with distal arms sclerotized where cerci are articulated; epiproct smaller than hypoproct, both with apical micropilosity ( Figs. 22, 23, 24 View FIGURES 13–24 ).

Female. Unknown.

Remarks. The new species Bryopharsos uncinatum and B. paulistensis have only one tenaculum in the cerci (except for the holotype, which has two tenacula in one cercus). The presence of one tenaculum is unique, as the other species of Bryopharsos have three to five tenacula. Bryopharsos uncinatum has five facet rows in the eye bridge, and the specimens does not have lobes in the anterior projection of the gonocoxal apodemes, while B. paulistensis has four facet rows and lobes are present in the anterior projection of the gonocoxal apodemes.
