Description.

This species was found in the Reserva Mamoré, Rondônia. It can be separated from other Xestoblatta species by the habitus (Fig. 23), coloration of the pronotum (Fig. 24) and head (Fig. 25), shape of the tergal modifications (Figs 26 and 27), and morphological differences in the subgenital plate (Fig. 28). In the original description, tergite VII and the right paraproct were not described. These characters are deemed very important to separate the species and therefore are described below.

Abdomen. Tergite VII with two lateral grooves (Figs 26 and 27). Supra-anal plate with right paraproct reaching beyond half of plate (Fig. 29). Also with two lobes, one convex at apex and covered with weakly sclerotized setae, and the other slender, curved and larger than the first (Fig. 30). Genital plate with left phallomere hooked (Fig. 31); median sclerite slender, lanceolate (Fig. 32); right phallomere shaped as inverted “Y” and with sclerotized base (Fig. 33).
