Etymology. The specific epithet refers to the type locality, the municipality of Cariacica. Occurrence. Reserva Biológica de Duas Bocas (20°16'19.05"S, 40°28'42.53"W), Cariacica, Espírito Santo state, Brazil.
Diagnosis. This species may be distinguished by the combination of the following characters: (i) apical projection of the pseudepiphallic median lobe longer than wide and with curved end (Fig. 4 C, F); (ii) ventral projection of the pseudepiphallic median lobe directed to the median portion of the genitalia (Fig. 4 A, D); (iii) pseudepiphallic apical lobe with sub-straight posterior and anterior edges (Fig. 4 B, E); (iv) pseudepiphallic sclerite without evident dorsal slit (Fig. 4 B, E).
Description: Holotype, male, measurements (mm): BL: 4.98; MID: 0.68; PL: 1.02; WP: 1.38; MLF: 2.99; MLT: 2.11; MTL: 0.64; MTW: 0.9. Head dark brown, covered with long semi-erect dark brown bristles on its median region, presence of thin bristles covering its entire extension (Fig. 2 A, B, D); presence of a light yellow spot between lateral ocelli and eyes (Fig. 2 D); black and prominent eyes (Fig. 2 A, B, D); three ocelli present; antennal scape light brown, antennomeres light yellow; front and gena dark brown; mandible light brown with dark brown edges; clypeus whitish with upper portion light brown; labrum whitish; maxillary and labial palps white, maxillary palps with third palpomere greater than the first and second, but smaller than the fourth and fifth (Fig. 2 D); fifth palpomere with rounded apex (Fig. 2 D). Thorax (Fig. 2 A, B, D) pronotum wide than long; dark brown coloration, without apparent spots; presence of thin and short bristles covering its entire extension; row of dark brown bristles, semi-erect and densified at their anterior and posterior edges; bristles also present, spaced out, over the entire extension; lateral lobes as in Figure 2 D; metanotum without any evidence of glands. Tegmina (Figs. 2 A, B, D and 3A, B) reduced, with parallel veins and without specialization; posterior wings absent. Prosternum and mesosternum with central portion light yellow, anterior and lateral edges dark brown (Fig. 2 C); metasternum light yellow. First pair of legs with trochanter, coxa and femur light brown; tibia light yellow, without tympanum and with one apical spine; femur and tibia with the presence of long black bristles; tarsomeres light yellow. Second pair of legs with trochanter, coxa and femur light brown; tibia light yellow, with two apical spines; femur and tibia with bristles similar to anterior leg; tarsomeres light yellow. Third pair of legs with trochanter, coxa and femur light yellow, femur with presence of some black bristles on dorsal and ventral surface (Fig. 2 A, B); tibia light yellow with seven dorsal spurs, being four inner and three outer (Fig. 3 C), where the inner proximo-dorsal spur reduced (Fig. 3 D); three inner and three outer apical spurs, with the median spur being the largest on the outer face (Fig. 3 F, "o.m"), and the superior spur being the largest on the inner face (Fig. 3 G, "i.s"); the two ventro-apical spurs, the inner and outer, with equal length (Fig. 3 E, arrows); tarsomeres light yellow (Fig. 3 F). Tarsal claws on all the legs with light yellow coloration. Abdomen (Fig. 2 A, B) with dark brown tergites. Cerci light yellow (Fig. 2 A–C).
Supranal plate whitish, with light brown spot on the central portion, light brown lateral edges and rounded posterior edge (Fig. 3 H). Sternites light brown (Fig. 2 C). Subgenital plate light brown, with sub-straight posterior edge (Fig. 3 I). Male paratype genitalia: Bristles or sensillas absent (Fig. 4). Apical projection of the pseudepiphallic median lobe longer than wide and with curved end (Fig. 4 C, F); pseudepiphallic sclerite without evident dorsal slit (Fig. 4 B, E); ventral projection of the pseudepiphallic median lobe directed to the median portion of the genitalia (Fig. 4 A, D). Ectophallic fold evident and not surpassing the pseudepiphallic parameres (Fig. 4 A, D). Endophallus divided into three sclerites, one central and two laterals (Fig. 4 A, D); endophallic sclerites forming a shell-shaped structure, in ventral view (Fig. 4 A, D); endophallic lateral sclerites without evident prolongations on external edges (Fig. 4 A, D). Female (Fig. 5 A–I): body shape similar to male, presenting the following differences: abdominal sternites light brown, with lateral thirds light yellow (Fig. 5 C). Subgenital plate light brown, with rounded posterior edge and with invagination in its central portion (Fig. 5 F). Ovipositor laterally flattened (Fig. 5 G–I) with length shorter than the posterior femora; dorsal and ventral valves varying from light yellow in their proximal portion to light brown on their distal edge; distal portion of dorsal and ventral valves serrated; dorsal valve with two rows of denticles of different size (Fig. 5 G, I).
