Figs. 7 , 9 , 15 , 16

Type specimens. Holotype male, 7 male, 7 female paratypes [ MZSP]; 12 male, 6 female paratypes kept at Departamento de Zoologia, Instituto de Biociências, UNESP—São Paulo State University, Botucatu campus.

Etymology. Toponymic, referring to the city of Porto Seguro, Bahia, Brazil.

Diagnosis. frons with oval yellowish maculae just below median ocellus; labrum light brown fading to yellow inferiorly (fig. 7D); fore wings reaching posterior margin of second abdominal tergite (fig. 7F), stridulatory vein with ca. 75 teeth; subgenital plate with the posterior margin concave (fig. 7I); pseudepiphallus slightly up-curved (fig. 9C), rows of denticles missing; ectophallic apodeme long (fig. 9A, B); copulatory papilla drop-shaped, distinctly depressed, the proximal margin of ventral face deeply invaginated.

Description. Male. Head: dark brown (fig. 7A); head in frontal view medium to light brown; three same-sized ocelli present (fig. 7D); maxillary palpi light to medium brown (fig. 7G); frons with oval yellowish maculae just below median ocellus; gena and clypeus medium brown, labrum light brown fading to yellow inferiorly (fig. 7D). Thorax: pronotum dark brown (fig. 7C); thoracic sternites as in fig. 7K. Fore wings reaching posterior margin of second abdominal tergite (fig. 7F); dorsal field with three harp veins; stridulatory vein with ca. 75 teeth; lateral field with parallel two parallel veins below angulation (fig. 16C). Legs: medium brown, excepting the lighter hind femora; tibia I with only internal tympanum present (fig. 7J). Abdomen: general color dark brown; supranal plate brownish under a yellow background, posterior margin broadly convex (fig. 7H), distal pigmented area with two whitish lines; subgenital plate light brown, darker laterally, the posterior margin concave (fig. 7I). Phallic Complex (figs. 9A, B, C): pseudepiphallus slightly up-curved (fig. 9C), its main lobe wider at base (fig. 9A, B), the apex truncate as seen by the sides, fringe of bristles located apically, rows of denticles missing; pseudepiphallic parameres round-tipped, touching each other; tip of ectophallic fold located at the level of distal margin of pseudepiphallus parameres; ectophallic apodeme long (fig. 9A, B). Female: general coloration similar to that of male (fig. 7B); copulatory papilla resembling that of the preceding species, drop-shaped, distinctly depressed, the proximal margin of ventral face deeply invaginated (fig. 15D2).

Material examined. 20 male, 13 female and 3 nymphs. Brazil, Bahia, Porto Seguro, Estação Ecológica Vera Cruz (16°21'S 39° 9'W), 23.x.2001, Costa et. al leg. All specimens preserved in 80% alcohol.
