Lestes pictus : A—Appendages, lateral view; B—Appendages, mediodorsal view. 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 .
