Type material. Holotype ³, Brazil, Sergipe, Santo Amaro das Brotas, “Gravata” 13 I 1979 ( MZUSP) . Allotype

♀ and Paratypes 1³, 2♀, same data as holotype ( MZUSP) . 1♀ Sergipe, Santo Amaro das Brotas, “871”, 10°46’51.2”S, 37°03’22.8”W (coordinates assigned à posteriori) ( MNRJ) GoogleMaps .

Diagnosis. Frons depressed below the antennal sockets and prominent above the ocelli. Ocelli positioned laterally. Pronotum dorsal surface slightly rough and striated, with two quite evident lobes with plain surface, and a wider central lobe covering the head. Short lateral margins with sharp angle and a conspicuous small spine. Legs longer and less robust. L1 sclerite with a lateral branch little sclerotized slightly curved downwards, smooth and with only a small spine and a region with a big lateral dilatation and an edge in the posterior median region with a lateral projection turned forward. Crown with a smaller number of sclerotized spines in the posterior region. L2d sclerite, hook with subconical and very wide anterior region. Sclerite N triangular on the dorsal region. R3d with a slight depression in the dorsal median region.

Description. Male. Head subtriangular, with interocular space measuring 1/4 of the distance between the antennal sockets. Frons with a depression below the antennal sockets and prominent above the ocelli. Frontal suture localized in a deep cuticular invagination, ocelli developed and positioned laterally (Fig. 10C). Pronotum transverse, pentagonal, dorsal surface slightly rough and striated, with two quite evident lobes with plain surface and a wider central lobe covering the head, anterior margin rounded, short lateral margins with sharp angle and a conspicuous small spine, hind margin nearly straight (Fig. 10B). Legs longer than in other species and less robust. Fore-femora ventro-anterior margins with 24 or 22 spines slightly decreasing in size from basal to apical; ventro-posterior margins with 5 spines. Middle legs ventro-anterior margins with 5 spines. Supra-anal plate quadrangular with setae on the surface, hind margin straight and slightly rounded laterally, bilobed, lobes very narrow and with a strong invagination in the median portion. Subgenital plate asymmetrical with long styles, funneled in the apical region. L1 sclerite apical region with two distinct parts: a lateral branch little sclerotized slightly curved downwards, smooth and with only a small spine, and a region with a big lateral dilatation and an edge in the posterior median region with a lateral projection turned forward. Crown with a smaller number of sclerotized spines. (Fig. 10G, H). L2d sclerite hook with subconical and very wide anterior region, a median apical region, and a narrow space connecting them. Apex internal cavity concave with short lateral external margin and narrow subapical notch (Fig. 10F, I). R2 sclerite cleft sclerotized, curved inward with a conic opening at its base and an apex directed upwards. Sclerite N triangular on the dorsal region (Fig. 10D) and with a small surface in the ventral one. R3d with a slight depression in the dorsal median region and narrow in ventral view (Fig. 10D, E). R 3v sclerite with a long, rectangular and slightly wide latero-distal region, and quadrangular caudal branch very near R3d (Fig. 10E).

Female ( Allotype). Head rounded, with wide interocular space measuring 1/2 of the distance between the antennal sockets. Eyes with curved interocular margin. Ocelli developed and deflected. Frons broad, frontal suture with a large cuticular invagination (Fig. 9H). Pronotum subtriangular, dorsal surface slightly rough and striated, with two quite evident lobes with plain surface, and a wider central lobe covering the head; anterior margin rounded, lateral margins short with sharp angle and a conspicuous small spine, hind margin nearly straight (Fig. 9F). Tegmina latero-anterior angle nearly straight; lateral margin wider, and hind margin with a strong curvature near the radial vein; extends further than the third abdominal tergite. CuP vein very marked (Fig. 9E). Legs short and robust. Fore-femora ventro-anterior margins with 19 small spines of the same size, ventro-posterior margins with 4 spines. Middle legs ventro-anterior margins with 9 spines. Supra-anal plate bilobed with a median incision, and each lobe with straight posterolateral angles (Fig. 9G).
