Notes In Straneo & Ball (1989) the geographical distribution of P. laeve is restricted to “ Espiritu Santo ” (probably a misspelling of the state of Espírito Santo ), but the lectotype and the paralectotype are labelled “Novofriburgo”, referring to “Nova Friburgo”, a city in the state of Rio de Janeiro . Those specimens are from the Atlantic province, in the Paraná biogeographic dominion. The new records are from Pampean province in the Chacoan subregion and from the Paraná Forest dominion in the Paraná dominion. Complementary description ABDOMINAL TERGITE IX ( Fig. 9M ). Oval, asymmetrical, sides converging to short-pointed projection expanded at base; inner anterior angle rounded; base rounded. AEDEAGUS ( Fig. 9K–L, N–O ). With median lobe ( Fig. 9K–L ) cylindrical, elongate, asymmetrical, slightly broadening apically; ostium short, confined to apical third; apical lamella short, abruptly narrowed, apical edges narrow; basal bulb thin; parameres ( Fig. 9N–O ) asymmetrical; left paramere longer and thinner than right paramere. GONOCOXITE 1 ( Fig. 9P ). Outer and inner sides arcuate; inner side forming acute projection on posterior margin; anterior margin dull. GONOCOXITE 2 ( Fig. 9P ). Elongate; basal lobe bearing ensiform setae on each side; ensiform setae long, with one-third to half the length of gonocoxite 2; slender setae at apex. MEASUREMENTS (in mm).
