Diagnosis. This species is characterized by having two intercalated rows of spines in the ventro-anterior margins of fore-femora; one row with 5 or 6 spines, and another with 32 or 33 spines of the same size. L1 sclerite with lateral branch curved, rounded and smooth with some small spines, and a curved region with grooves in its interior and a projection with a rounded end directed upwards at its right side. L2d sclerite hook with long apical region, and rounded curvature of the margin near the notch. R2 sclerite cleft curved inward with a wide and sclerotized apex directed forward. R3d with a clear prominence like a tooth in ventral view. R 3v sclerite with quadrangular and truncated latero-distal region, and caudal branch near the tooth from R3d sclerite.

Description. Male. Head subtriangular, interocular space approximately 1/3 distance between antennae. Frons slightly elevated. Ocelli developed and deflected. Frontal suture with a cuticular invagination (Fig. 14C). Pronotum pentagonal, fore margin rounded, with rounded lateral angles, hind margin slightly curved in the medial portion (Fig. 14B). Legs short and robust. Fore-femora ventro-anterior margins with two intercalated rows of spines, one with 6 or 5, and another with 33 or 32 spines of the same size; ventro-posterior margins with one large and a thin spine out of the row, 6 small spines. Middle legs ventro-anterior margins with 11 or 10 spines. Tegmina with orange lateral margins in the first half of its length (Fig. 14A). Supra-anal plate quadrangular with setae on the surface, hind margin straight and slightly rounded laterally, bilobed with a slight invagination in the median portion. Subgenital FIGURE 14.

plate asymmetrical with long styles, left funneled in the apical region, right with same caliper all along. L1 sclerite with apical region with two distinct parts: a lateral branch curved, rounded and smooth with some small spines, and a curved region with grooves in its interior and a projection with a rounded end directed upwards at its right side (Fig. 14G, H). L2d sclerite hook with long apical region and rounded curvature of the margin near the notch (Fig. 14F, I). R2 sclerite cleft curved inward with a wide and very sclerotized apex directed forward (Fig. 14D). Sclerite N tiny in dorsal and large and wide in ventral view. R3d with a clear prominence like a tooth in ventral view (Fig. 14D, E). R 3v sclerite with quadrangular and truncated latero-distal region, and caudal branch near the tooth from R3d sclerite (Fig. 14E).

Female (Paratype). Head rounded, with wide interocular space measuring approximately 1/2 the distance between the antennal sockets. Eyes with straight interocular margin. Ocelli developed and slightly deflected. Frontal suture with a cuticular invagination. Clypeus distal half transparent yellow and larger (Fig. 15D). Pronotum subtriangular with anterior region rounded and slightly concave near the margins; dorsal region rough with deep striae, lateral angles rounded ending in a corner and hind margin slightly curved in the median region (Fig. 15B). Tegmina with little rounded lateral anterior angles, orange lateral margins, and rounded and curved hind margins. Long, reaching the fifth abdominal tergite (Fig. 15A). Legs short and robust. Fore-femora ventro-anterior margins with 31 or 32 spines of the same size; ventro-posterior margins with 3 spines. Middle legs ventro-anterior margins with 5 spines. Supra-anal plate bilobed with a very small median incision. Lobe lateral margins slightly rounded and posterior margin straight (Fig. 15C). Tergites with rounded lateral angles (Fig. 15A).

Measurements (mm). Holotype ³: Body length 52.80; pronotum length 12.05 × 17.35 maximum width; teg- men length 40.75 × 14.70 width; interocular width 1.7; interantennal width between sockets 5.5. Paratypes ³: Body length 52.60–64.30; pronotum length 11.15–14.13 × 15.08–19.07 maximum width; tegmen length 36.16–42.34 × 13.81–20.73 width; interocular width 0.9–1.2; interantennal width between sockets 2.5–3.1.

Allotype ♀: Body length 42.52; pronotum length 11.03 × 17.86 maximum width; tegmen length 17.05 × 12.55 width; interocular width 3.1; interantennal width between sockets 5.6. Paratypes ♀: Body length 39.15–47.18; pronotum length 10.04–12.22 × 16.12–19.41 maximum width; tegmen length 14.86–18.72 × 0 9.92–13.34 width; interocular width 1.4–1.6; interantennal width between sockets 2.7–3.0.

Coloration. Holotype ³: General coloration dark brown (Fig. 14A). Pronotum dark brown with the anterior margin yellowish brown; central disk orange brown with scattered dark brown marks (Fig. 14 B). Head dark brown; clypeus and labrum yellowish brown. Antennae with basal segments dark pigmented and apical segments whitish yellow. Ocelli pale brown (Fig. 14C). Legs dark brown and spines brown; pulvilli white, tarsal claws and arolia light brown. Tegmina with orange lateral margins and abdomen following general coloration of body (Fig. 14A).

Etymology. The word kaingangue derives from the Tupi—Guarani. It is the name of an Indian group originally distributed from S„o Paulo to Rio Grande do Sul. The name is an allusion to the similarity of their distribution ranges and a tribute to this people that were certainly aware of the existence of this cockroach.

Distribution. Brazil (S„o Paulo, Santa Catarina, Rio Grande do Sul). See Fig. 17 for details.
