Bioacoustics of Anabropsis (Spinanabropsis) pengi

Figures 7–8 Description. Male. Body medium, wingless. Fastigium verticis projecting forward, dorsal surface of head with a distinct longitudinal carina along the midline ( Fig. 7 ). Eyes oval, projecting outwards. Ocelli distinct, medium ocellus longer than wide; lateral ocelli oval, located on both sides of fastigium verticis.Apical segments of maxillary palpi slightly swollen ( Fig. 7A ). Disc of pronotum rough, anterior margins projecting forward, with an indistinct longitudinal carina; ventral margins of lateral lobes arched, without humeral sinus ( Fig. 7C ). Prosternum with 1 pair of short spines, basal areas separated, apices subacute; mesosternum with 1 pair of spines, basal areas separated, internal margins obliquely outward, apices subacute; metasternal lobes subtriangular, basal areas separated, apices obtuse ( Fig. 7D ). Fore coxae with 1 short spine, relatively robust; middle coxae swollen, without spines. All femora unarmed on ventral surfaces; genicular lobes of fore and middle femora with apices obtuse; genicular lobes of hind femora with 1 small internal spine, apices of external genicular lobes obtuse, external surface with distinct oblique stripes. Dorsal surface of fore tibiae with 1 internal spur nearly the middle and 1 pair of apical spurs; ventral surface with 3 pairs of spurs, 1 pair of subapical spurs and 1 pair of apical spurs; basal areas of tibiae with opened tympana on both sides ( Fig. 7F–G ). Dorsal surface of middle tibiae with 3 internal spurs, 2 external spurs and 1 pair of apical spurs; ventral surface with 3 pairs of spurs, apices with 1 pair of subapical spurs and 1 pair of apical spurs, equal length between external and internal spurs. Dorsal surface of hind tibiae with 10 internal and 11 external spines, apices with 1 pair of spurs; ventral surface with 2 external spines, subapices with 1 pair of spurs, apices with 1 pair of long and 1 pair of short spurs, the internal spurs nearly the same length as the external one. First to fourth abdominal tergites with stridulatory pegs ( Fig. 7E ). Posterior margins of ninth abdominal tergite straight. Posterior margin of tenth abdominal tergite arched concave, lateral margins with 1 pair of hooks its apices pointing inward. Paraproctal processes with 1 pair of long processes, directing upwards and backwards from their bases. Cerci conical, approximately equal in length to the paraproctal processes ( Fig. 7K–H ). Subgenital plate shorter than cerci; basal half broad, the lateral margins obviously convex, then narrowing to middle area; ventral surface with 1 pair of parallel longitudinal carinae, between of which concave; posterior margin straight. Styli short, inserted at the apico-lateral margins ( Fig. 7H–J ). Female. Body medium. Cerci conical, slightly upcurved, apices acute. Basal area of subgenital plate triangular, about 3–4 times as long as apical spine ( Fig. 8J ). Basal half of ovipositor relatively stout, narrowing to apices, upcurved, dorsal valvulae longer than ventral ones, apices of dorsal valvulae subacute ( Fig. 8H–I ). Coloration. Dorsal surface of head, pronotum and anterior half of abdomen black brown, the other parts brown, with short pale longitudinal stripes ( Figs. 7A–B , 8E, H ). Abdominal sternites and fore and middle femora yellowish; hind femora yellowish, external surface with black vertical stripes ( Figs. 7N , 8D, K ). Ocelli and maxillary palpi yellowish ( Figs. 7A , 8A ). Ventral surface of abdomen tawny. Ovipositor yellowish brown with irregular black spots ( Fig. 7H ). Measurements (mm). Male: BL 22.1, PL 6.8, HTL 23.3, HFL 22.0. Female: BL 20.0–22.7, PL 5.4–6.3, HTL 18.1–19.4, HFL 17.2–18.7, OvL 8.6–9.5.
