Pepoapua Jesus & Pereira n. gen. (Figs. 2–5)
Type species. Pepoapua cariacica Jesus & Pereira n. sp.
Etymology. “ Pepoapua ” (pronounced /pepəɑpuːɑ/), a compound of two words from the native South American Tupi-Guarani language. “ Pepó ” means wing and “apu’a” means short. Name given in allusion to the fact that the species here described present short wings.
Diagnosis. This new genus is characterized by the combination of the following characters: (i) males and females with morphologically similar tegmina (Figs. 2 A, B, D; 3A and 5A, B, D); (ii) tegmina reduced, not reaching half of the second abdominal segment (Fig. 2 A, B, D); (iii) dorsal field of the tegmina with parallel veins, without stridulatory vein or any specialized area for sound production (Fig. 3 A); (iv) tibia of the first pair of legs without tympanum; (v) tibia of the third pair of legs with seven dorsal spurs, four inner and three outer (Fig. 3 C), the proximo-dorsal inner spur reduced in size (Fig. 3 C, D) and the disto-dorsal inner spur without glandular aspect (Fig. 3 C); (vi) ovipositor with distal portion of the dorsal and ventral valves serrated (Fig. 5 G–I); (vii) male genitalia without evident bristles or sensillas (Fig. 4); (viii) pseudepiphallic median lobe presenting apical and ventral projections (Fig. 4 A, C, D, F).
Description. Small size (Ẽ 6mm). Head as wide as pronotum (Fig. 2 A), covered by long semi-erect dark brown bristles on fastigium, vertex and occiput; presence of thin bristles covering its entire length; black and prominent eyes (Fig. 2 A-D); three ocelli present; 5-segmented maxillary palps, with the third being larger than the first and second, but smaller than the fourth and fifth palpomere (Fig. 2 D); fifth palpomere with rounded apex (Fig. 2 D). Pronotum wider than long, covered with long and fine bristles of dark brown coloration; anterior and posterior edges with a row of long dark brown bristles (Fig. 2 A, B, D); lateral lobes as in Figure 2 D; tegmina reduced, with parallel veins and without specialization (Figs. 2 A and 3A); posterior wings absent; tympanum absent; tibia of the first pair of legs with an apical spur; tibia of the second pair of legs with two apical spurs; tibia of the third pair of legs with seven dorsal spurs, being four inner and three outer (Fig. 3 C), the proximo-dorsal inner spur reduced in size (Fig. 3 D) and the disto-dorsal inner spur without glandular aspect (non-specialized) (Fig. 3 C); presence of three inner and three outer apical spurs, with the median spur being larger in size on the outer face (Fig. 3 F, "o.m") and the superior spur being larger in size on the inner face (Fig. 3 G, "i.s"). Male genitalia: bristles or sensillas absent (Fig. 4); pseudepiphallic median lobe presenting apical and ventral projections (Fig. 4 A, C, D, F); endophallus divided in three sclerites, being one central and two laterals (Fig. 4 A, D); rami fusioned with pseudepiphallus (Fig. 4 A, C, D, F). Ovipositor flattened laterally, dorsal and ventral valves serrated in distal portions (Fig. 5 G–I).
