New species of arboreal predatory katydids from West Africa (Orthoptera: Tettigoniidae: Meconematinae) Author Naskrecki, Piotr text Zootaxa 2008 1732 1 28 journal article 10.5281/zenodo.181351 1f016037-2ea8-46e7-82e1-be6826ae0389 1175-5326 181351 Anepitacta (Anepitacta) wrightae 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 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 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 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 ). 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 ). 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.
