Distribution ( Fig. 43View FIGURE 43). Brazil (Rio de Janeiro, Espírito Santo, São Paulo, Santa Catarina, Rio Grande do Sul).

New records. Additional specimens of I. pulverulentus  were collected in the states of Espírito Santo and São Paulo, Brazil thus increasing the known distribution of this species.

Principal characteristics. Head dark brown; vertex, frons to below antennae, and genae fuscous; edge of the clypeus with black spots; antennae pale amber, scape and pedicel brown, flagellomeres covered with elongated pale yellow setae. Pronotum testaceous with many black spots and long setae, twice as long as broad; meso- and metanota yellowish, with two black spots and elongated brown setae. Legs pale amber with some dark brown spots; covered by elongated pale amber setae. Wing membrane hyaline, veins alternating brown and pale yellow, pterostigma well-marked with a mottled coloration pattern ( Fig. 24View FIGURE 24 C); forewing with many brown spots; forewing with many dark brown spots mainly in wing margin, radial and medial trace, nygmata dark brown; hindwing without dark spots. Abdomen testaceous, with many dark brown spots.

Male ( Fig. 25View FIGURE 25). Ninth sternite short, rounded posteroventrally; ectoproct obliquely truncated, posteroventrally with a prominent lobe rounded at apex; ninth gonocoxites with medial lobe rounded, apical margin and center excised; ninth gonapophyses shapes as quadrate plates; complex of tenth gonocoxites with basal portion fused, broad; upper branch near apex elongate, apex sharply pointed.

Female ( Figs. 26View FIGURE 26, 27View FIGURE 27). Seventh sternite with rounded posterior margin; fused ninth gonapophyses curved dorsad in lateral view, ventromedially with a small rounded lobe projected anteroventrally, apex with lateral rounded lobes; in ventral view Y-shaped, apical lobes anterolaterally directed, short and blunted, distal margin concave; ninth gonocoxites lanceolate with a small gonapophysis at apex and a process near to the base.
