Types. Syntypes in MCZ (not examined) .

Larva described. Yes ( Santos 1972, additions by Costa & Carneiro 1994).

Material examined. (4 ♂♂ + 2 ♀♀): 1♂ Brazil: São Paulo, Rio Claro, Sítio Primavera , 31.xii.1995, F.A.A. Lencioni leg. ; 1 ♂ + 1 ♀ Brazil: São Paulo, Salesópolis (brejo na margem do Rio Pardo ), 28.ix.1996, (in tandem), F.A.A. Lencioni leg. ; 2 ♂♂ + 1 ♀ Brazil: São Paulo, Santa Branca—Margem do Rio Paraíba do Sul , 06.xii.2008, E.A. Lencioni leg.

Distribution. Brazil (Mato Grosso, Espírito Santo, Rio de Janeiro, São Paulo), Peru and Argentina (Misiones).

Diagnostic characters. ♂ — Cercus in lateral view: basal 1/4 straight, apical 3/4, formed by the fusion of medial and apical portions, almost rectangular. Cercus in mediodorsal view: base of cercus without spine, medial expansion almost completely fused with the apical portion of cercus, forming a roughly rectangular plate, with only a small apical tip. Paraproct in lateral view: more than half the size of the cercus, with a tuff of pale hair–like setae directed upward. Paraproct in dorsal view: finger–like.

♀ —Basal plate: species belonging to basal plate group 1 ( Fig. 38 ), with dorsal side a little longer than ventral side. Posterior side with ventral section twice the length of the dorsal section. Dorsal side straight and ventral side slight convex ( Fig. 39E ). Pectoral color pattern as in Fig. 40J .
