Bioacoustics of Liara (Liara) shii

石氏ffø FIGURES 5–10 Description. Male. Body stout. Fastigium verticis conical in dorsal view ( Fig. 5B ), ventral surface with indistinct median carinula ( Fig. 5A ). Face strongly punctured ( Fig. 5A ). Pronotum rugose, anterior margin almost straight with faintly concave, posterior margin widely arched, transverse sulcus broadly interrupted in middle ( Fig. 5B ); the lateral lobes longer than high, anterior angle broadly rounded, posterior angle obtusely rounded, humeral sinus faintly exposed ( Fig. 5C ). Prosternum smooth; mesosternal lobes long and stout; metasternal lobes obtuse; intermedial plate with small obtuse tubercle at posterior angles ( Fig. 5D ). Genicular lobes spine-shaped, the internal ones obviously longer than the external. Fore coxae with 1 long spine ( Fig. 6A ); femora with 6–7 internal spines on ventral surface, tibiae ventrally with 7–8 pairs of spines and one pair of apical spines. Middle femora with 7 external spines on ventral surface; tibiae with 4 internal and 10 external ventral spines, apices with 1 pair of ventral spines. Hind femora with 6 external spines on ventral surface; tibiae dorsally with 9–11 internal and 11–12 external spines, ventrally with 3–4 internal and 5–6 external spines, apices ventrally with 1 pair of dorsal spurs and 2 pairs of ventral spurs. Tegmina reaching the middle area of fifth abdominal tergite, apices obtusely rounded and not overlapped ( Fig. 6A ), stridulatory file with 125 teeth ( Fig. 6C ); hind wings shorter than the tegmina. Tenth abdominal tergite prolonged, posterior margin concave in the middle, the lateral lobes obtuse ( Figs. 5I , 6D ). Cerci stout, terminating to apices, internal margin of basal area with 1 long digitiform process ( Fig. 5G ); divided in apical area: dorsal branch stout, curved inward, apex acute ( Figs. 5H–I , 6D ); ventral branch long and sinuate, subapical area slightly expanded on internal margin, apex obtuse with 1 small spine ( Figs. 5H–I , 6E–F ). Sclerites of titillators with apical parts short, curved, denticulate; distal parts of ventral edges with large, subtriangular, sclerotized lateral lobes, which bulging and curved ( Fig. 6E–F ). Subgenital plate longer than wide, lateral margin curved dorsad, the middle area of the lateral margin slightly convex, posterior margin triangular concave ( Fig. 5J ); styli short inserted at the lateral angle of subgenital plate. Female. Tegmina shorter than male, only reaching the middle area of first abdominal tergite ( Figs. 7D , 8A ). Tenth abdominal tergite with posterior margin slightly concave in middle ( Fig. 8C ). Epiproct triangular, apex rounded ( Fig. 8C ). Cerci conical, apices slightly curved mediad. Subgenital plate longer than wide, posterior margin obtusely rounded concave, apico-lateral angles acutely projecting ( Fig. 7F ). Ovipositor gradually curved upward with both margins expanding to middle area, then terminating to apices ( Fig. 9C–D ); apices obtuse ( Fig. 8B ). Coloration. Brown purple ( Fig. 9 ), dorsal surface brown to black, ventral surface purple. Eyes, the margins of the antennal cavities, the base of the first and second antennal segments ( Figs. 5A , 7A ), the middle of the clypeal suture, the apices of femora, the dorsal surfaces of the basal third of the fore tibiae, the bases of the middle and hind tibiae black ( Fig. 9 ). Face with dark green longitudinal band ( Figs. 5A , 7A ). Dorsal surfaces of head, pronotum and tegmina black brown ( Figs. 5B , 7C–D ). The venation of the tegmina are yellowish brown (brown membranes are located between the veins). Measurements (mm).
