Types. Unknown.

Larva described. Yes ( Muzón 1997).

Additional material examined. (2 ♂♂ + 2 ♀♀): 2 ♂♂ + 2 ♀♀ Argentina: Buenos Aires, Los Torinas, charco s/ Rt 11, 18.i.1995, J. Muzón leg.

Distribution. Brazil (Rio Grande do Sul), Uruguay, Argentina, Chile.

Diagnostic characters. ♂ —Cercus in lateral view: basal 1/2 straight, slightly inclined upward, apical 1/2 comma–like with a twisted tip which is covered with pale setae; Cercus in medioventral view: basal expansion semicircular, without spines, a ridge separating the medial portion from the apical portion. Paraproct in lateral view: stout and very small (1/8 length of cercus). Paraproct in dorsal view: barely visible and slightly triangular.

♀ —Basal plate: species belonging to basal plate group 1 ( Fig. 38 View FIGURE 38 ), with dorsal side more than twice the length of ventral side. Posterior side with dorsal and ventral sections subequal. Dorsal side and dorsal section of posterior side straight, ventral section of posterior side concave ( Fig. 39G View FIGURE 39 ). Pectoral color pattern as in Fig. 40M View FIGURE 40 .
