Anepitacta (Anepitacta) wrightae View in CoL n. sp.

(Figs. 2J– O; 4D, N; 5A; 6D, E)

Differential diagnosis. This species is closely related to A. (A.) guentheri Gorochov , from which it differs in the strong reduction of wings, and the shape of the male cercus (the male cercus is equipped with a larger, more distended apical part in A. guentheri .) The 10th male tergite of the new species also resembles that of A. (A.) inconspicua Br. -Watt., but the latter has a small and partially membranous apical part of the male cercus, and is macropterous. The female subgenital plate of A. (A.) wrightae resembles that of A. (A.) guineensis Beier , but the latter is also macropterous.

Description.

General. Body small, slender; brachypterous ( Fig. 6 View FIGURE 6 E).

Head. Fastigium of vertex triangular, blunt apically, not reaching apex of antennal sockets, flat dorsally; antennae more than twice as long as body; frons flat, vertical; eyes circular, weakly protruding.

Thorax. Lateral lobe of pronotum wider than high; humeral sinus of pronotum absent ( Fig. 6 View FIGURE 6 D); anterior margin of pronotum flat; metazona flat; posterior edge of metazona narrowly rounded.

Legs. Legs slender. Front tibia unarmed dorsally, with 5 spines on posterior and 4 on anterior ventral margin; tympanum bilaterally open, oval; genicular lobes of front femur unarmed; front femur unarmed ventrally; mid tibia very weakly thickened in proximal ¾, with 3 spines on posterior and 5 on anterior ventral margin; mid femur unarmed ventrally; genicular lobes of mid femur unarmed. Hind femur unarmed ventrally; genicular lobes of hind femur unarmed.

Wings. Wings reduced, tegmen barely reaching 5th abdominal tergite; anterior margin broadly rounded; hind wing reduced, half as long as tegmen. Costal field slightly widened at base; veins Sc and R close together, parallel along their entire length; Rs detached from R, starts before middle of tegmen, without secondary branches; right stridulatory area with large, fully developed mirror; left stridulatory area with large, fully developed, roughly rectangular mirror ( Fig. 4 View FIGURE 4. A – J N). Stridulatory file elevated on thickened vein, nearly straight, bent in proximal fourth, with 147 teeth, 0.49 mm long, 0.04 mm wide ( Fig. 4D View FIGURE 4. A – J ).

Abdomen. Tenth tergite with posterior edge sclerotized, forming paired, long lobes overhanging epiproct (Figs. 2J, M); epiproct strongly modified, forming large, paired, sinuous structure (Fig. 2L), styli parallel. Cercus with small, basal tooth, S-shaped, held vertically; apex strongly flattened dorso-ventrally and distended laterally (Fig. 2K); paraprocts unmodified; epiphallus weakly sclerotized, with central, bulbous structure covered with tiny denticles ( Fig. 5A View FIGURE 5. A – C ). Subgenital plate unmodified. broadly trapezoidal; straight apically; styli cylindrical, about 4 times as long as wide. Female subgenital plate roughly rectangular, about 1.5 times longer than wide (Fig. 2 O).

Ovipositor. Ovipositor normally developed; slightly curved, slightly shorter than hind femur (ratio femur/ ovipositor 1.06–1.13); apex of ovipositor pointed, with apex of lower valvula slightly bent downwards; edges of both valvulae smooth, dorsal edge of upper valvula parallel to lower valvula (Fig. 2N).

Egg. Egg elongate; without external appendages.

Coloration. Coloration olive green; antennae concolorous; eyes uniformly colored; face without darker markings; occiput with brown band; pronotum with light brown band and dark markings on posterior edge; tegmen green, with posterior edge brown; hind wing hyaline; hind legs uniformly colored; abdominal sterna and subgenital plate without markings.

Measurements (5 males, 7 females). body w/o wings: male 10–12 (11±1), female 8–11 (9.5±1.2); pronotum: male 3.5–4 (3.9±.2), female 3.3–4 (3.6±.2); tegmen: male 3.4–3.7 (3.5±.1), female 3.2–3.5 (3.4±.1); hind femur: male 8.5–9.3 (8.9±.3), female 9–10 (9.4±.4); ovipositor: 8–9 (8.4±.4) mm.

Jengre - 1 female, 1 male (paratypes) ( ANSP).
