Type material.

Holotype male: " Brazil: Paraná, Ponta Grossa, Vila Velha [-25.25, -50.01] 14-16VIII/2009, Grossi & Parizotto (leg.)" / “fezes” / "Caterino/Tishechkin Exosternini Voucher EXO-00751" (DZUP). Paratypes (2): same data as type (CESP, CERPE).

Diagnostic description.

Length: 1.69-1.81 mm (avg. 1.76 mm); width: 1.54-1.65 mm (avg. 1.62 mm). This species is extremely similar to the preceding ( P. curvipes ) in external morphology (though not in male genitalia), differing principally in the following characters: body not bicolored, more less uniformly piceous frontal ground punctation slightly more conspicuous; right mandible with strong basal tooth (possibly not a difference from the preceding, in which it could not be observed); median pronotal gland openings 2/3 behind anterior pronotal margin; lateral secondary pronotal punctures more numerous and covering most of the outer 1/4 of the pronotal disk; 1st dorsal elytral stria obsolete in the apical 2/3; 2nd through sutural elytral striae distinctly comprising series of disconnected punctures; 4th stria present only in apical 2/3, 5th stria with no basal arch; secondary pygidial punctures sparse but extending nearly to apex; prosternal keel striae obsolete in anterior 1/2; protibia more strongly curved; Male: S8 without apical processes; aedeagus with basal piece ~ 1/3 length of tegmen; tegmen slightly widened to near apex, then evenly narrowed to subacute apices, apex slightly curved ventrally in lateral view; medioventral process absent; median lobe ~ 2/3 tegmen length, basal apodemes abruptly narrowed in basal 1/3.

Etymology.

This species is named for the Parque Estadual Vila Velha, the only known locality for this species.

Distribution.

This species is only known from the type locality in Paraná, Brazil.
