Identification. The coloration of the body is very similar to almost identical to that in P. durus . Colour pattern as in Figs 62–68 . Male tarsomere I of mesotarsus distinctly longer than others together ( Fig. 69 ). Pygidium of male elongate, ratio of the maximum length to maximum width 1.36 ( Fig. 66 ), pygidium of female also with distinct promontory before apical edge, but this projection is not so high and not deeply divided basally as in P. durus . Eyes longer (cf. Figs 44 , 50— P . durus; and 63— P. lateralis ), dorsal ocular index 0.66 in male. Body size 4.5–4.9 mm.

Lectotype, male ( Figs 62–67 ). Measurements (in mm): Total body length—4.86. Head: total length—0.86, length of rostrum—0.23, maximum width of rostrum—0.93, length of eye—0.66, maximum width across eyes— 1.21, minimum distance between eyes—0.30.Antenna: length of segments: II—0.21, III—0.36, IV—0.36, V—0.26, VI—0.24, VII—0.20, VIII—0.21, IX—0.19, X—0.13, XI—0.19, width of segment IX—0.14. Pronotum: maximum length—1.13, maximum width—1.63, minimum width—1.13. Elytra: maximum length—2.90, maximum width— 1.60. Pygidium: maximum length—0.64, maximum width—0.47.

Distribution. Brazil, Paraguay ( Jordan 1904, Rheinheimer 2004).
