( Figs. 7 A–B View FIGURE 7 A – B ; 8 A–D)

Type material. Holotype [adult male]: BRAZIL, Espírito Santo, Pancas, Fazenda Juliberto Stur, 31.I–07.XI.2003, 19º 13 '10,5"S 40 º 46 '23,8"W, Tavarez, M. T. & Azevedo, C., (Malaise trap) ( MZFS # 55699). Paratypes. 2 Males, BRAZIL, Espírito Santo, Cariacica, Reserva Biológica Duas Bocas, 20 º 18 '05''S 40 º 28 '06''W, 28.I. 2009, Santos, C. B., (light trap CDC) ( MZFS # 55700, # 55701).

Diagnosis. Adult. Hypandrium plate-like, wider than long, bilobed, lobes with few bristles at apex; ejaculatory apodemes short, approximately 0.6 times the length of the aedeagus, trapezoidal, with rounded ends; paramere fused with aedeagus; cercus with long apical tenacula, approximately one half the length of the cercus; cercus with 14 or 15 short, rod-like accessory tenacula dispersed along the distal half of its dorsal surface.

Description. Adult Male: Eyes separated by less than one facet diameter, almost contiguous; interocular suture inverted U-shaped; eye bridge with 4 facet rows. Antenna incomplete. Ratios of palpus segments 10: 20: 22: 26. Wing infuscate, with small clear areas between the vein tips, with small dark areas at the bases of R 5, the radial fork, and CuA 1; radial fork more basal than medial fork. Hypandrium plate-like, wider than long, bilobed, lobes with few apical bristles; gonostylus 1.2 times the length of gonocoxite, narrow, half the width of gonocoxite, tapering towards the apex; ejaculatory apodeme short, approximately 0.6 times the length of the aedeagus, trapezoidal, with rounded ends; aedeagus narrower than gonostylus, tapering to a pointed apex; paramere fused to aedeagus, slightly wider than the aedeagus; epandrium broader than long, with bristles near the apical margin; cercus with one long apical tenaculum, approximately one half the length of the cercus; cercus with 14 or 15 short, rod-like accessory tenacula dispersed along the distal half of its dorsal surface.

Adult Female. Unknown.

Distribution. Know only from the type locality.

Etymology. The specific epithet refers to the large numbers of accessory tenacula.

Discussion. The gonostylus, ejaculatory apodeme, and apical tenaculum of the cercus are all similar in shape in P. hirsutus , P. moragai , and P. tango . These three species differ principally by their numbers of short, rod-like accessory tenacula along the cerci. While P. moragai has 3, and P. tango has 4 short rod-like accessory tenacula, P. hirsutus has 14 to 15. The three species also differ by a combination of other features: P. t a ng o has contiguous eyes, while the eyes of P. hirsutus and P. moragai are separated by less than one facet diameter; the aedeagus of P. tango and P. moragai are slightly sinuous, tapering at the apex, while the aedeagus of P. hirsutus is straight.
