Head. Frons slightly visible above eye margin in lateral profile; 2 reclinate ors and 2 reclinate inwards ori, similar in size; interfrontal hairs absent; orbital setulae erect in one row; facial keel undifferenciated; eye height/parafacialia+gena: 9; ocellar triangle short, ending well before second ors; lunule high, 25% of frons length; clypeus rounded; epistoma height 0.06 mm; first flagellomere rounded and finely pubescent; arista long, slightly longer than vertical height of eye, finely pubescent; vibrissa long and strong, measuring half of aristal length.  
 Thorax. Acr in six irregular rows; prsc absent; 1+3 dc, increasing in size from prescutelar; 2 npl, anterior one shorter than posterior. Wings. Wing tip nearer to R 4+5 than M; R 4+5 and M erect; C sections 2–4 in proportions: 0.71:0.14:0.14; ultimate section of CuA 1 1.37 length of basal section; r-m distal midpoint of dm. Legs. Fore tibia without pd; mid tibia with 1 pd on middle third.   
Terminalia. Epandrium rounded with long setae (Fig. 66); cercus short, about 1/3 height of epandrium and with long setae, 1 distinct at apex; postgonite with four setae on apex; surstylus triangular with about 45 setae; hypandrium U-shaped; phallapodeme about twice length of hypandrium; mesophallus simple; distiphallus elongated (Fig. 67); ejaculatory apodeme broad, at its broader part about 5.8 times wider than constricted area at base (Fig. 68). Oviscape (Fig. 69). Spermathecae (Fig. 70).  
Distribution. Rondônia and Mato Grosso do Sul (Brazil).  
Etymology. The specific epithet refers to the great number of setae on surstylus.  
 Remarks. This new species closely resembles P. simpla sp. nov. in wing length and general color of the body, but differs in having the frons mat black, greyish pollinose, and the presence of four setae on apex of postgonite, surstylus triangular with about 45 setae, phallapodeme about twice the length of hypandrium, distiphallus elongated, and ejaculatory apodeme broad with straight constriction.
