Monachoda angulata Saussure, 1870: 120 ; Finot, 1897: 207.

Examined material. Syntype ♀. Brazil, Bahia. ( MHNG)

Diagnosis. Pronotum triangular, with rounded anterior region slightly concave near the margins, inconspicuous dorsal roughness and striae. Lateral angles pointy, without corners, hind margin slightly curved in the median region. Tegmina anterior angle nearly square, hind margin truncated with a marked curvature towards the medial margin. CuP vein ending at the half of the hind margin. Supra-anal plate bilobed, lateral margins of each lobe very rounded.

Redescription. Female. Head subtriangular, with wide interocular space measuring 1/2 of the distance between the antennal sockets. Eyes with straight interocular margin. Ocelli developed and deflected. Front broad and frontal suture with a small cuticular invagination (Fig. 9D). Pronotum triangular, with anterior region rounded and slightly concave near the margins; dorsal roughness and striae inconspicuous. Lateral angles pointy, without corners, hind margin slightly curved in the median region (Fig. 9B). Tegmina very short and not extending further than the second abdominal tergite; anterior angle nearly square, hind margin truncated with a marked curvature towards the medial region. CuP vein ending at the half of the hind margin (Fig. 9A). Legs short and robust. Fore-femora ventro-anterior margins with 16 or 17 spines of the same size, ventro-posterior margins with 4 spines. Middle legs ventro-anterior margins with 4 spines. Supra-anal plate bilobed with a small median notch, each lobe with a very rounded lateral margin and a slightly straight hind margin (Fig. 9C). Tergites with quadrangular lateral angles (Fig. 9A).

Male. Unknown

Measurements (mm). Syntype ♀: Body length 30.70; pronotum length 10.00 × 17.57 maximum width; tegmen length 9.80 × 12.20 width; interocular width 2.6; interantennal width between sockets 5.6.

Allotype ♀: E) Habitus, dorsal view; F) Pronotum, dorsal view; G) Supra-anal plate, dorsal view; H) Head, ventral view. Scales: Habitus= 1cm, Pronotum= 5mm, Supra-anal plate= 5mm, Head= 2 mm.

Coloration. Syntype ♀: General coloration burnt umber (Fig. 9A). Pronotum burnt umber with a anterior margin ochre; central disk yellowish brown with scattered dark brown marks (Fig. 9B). Head burnt umber and clypeus and labrum dark brown (Fig. 9D). Antennae with segments yellowish brown. Ocelli ochre. Legs and spines dark brown; tarsal claws, pulvilli and arolia yellowish brown. Tegmina with anal field burnt umber and marginal field brown; abdomen following general coloration of body but with tergites and sternites hind margins dark brown (Fig. 9A). Supra-anal plate burnt umber (Fig. 9C).

Distribution. Brazil (Bahia).
