Bioacoustics of Xenicola superba

Amended diagnosis: Angara superba can be distinguished readily from other species by the following features: lateral carinae of pronotum crenelated; posterior edge of pronotal disc much wider than anterior edge; first abdominal tergite differing in colour from general body colour; area above lateral coloured band of different colour when compared with the general body colour. Complementary description: Overall aspect ( Figs 9A , 14F ): large-sized katydids, general colour brown or yellow, and a laterally coloured strip from head to abdominal tip. Head ( Fig. 9B, C ): frons and gena rugose, brownish, or yellowish with black spots; fastigium of frons triangular, higher than wide, ocelli present. Clypeus brownish or yellowish proximally, dark brown or dark yellow at apex. Labrum light brown or whitish; maxillary and mandibular palps brownish or greenish. Scape as long as 0.4× of pedicel; scape and pedicel entirely black; flagellum ≥ 3× longer than body, first nine flagellomeres dark yellow, then five articles brown, three articles white, 15 articles brown, seven articles white, finishing in brown articles. Fastigium of vertex elevated, one lateral ocellus near half of fastigium of vertex. Thorax ( Fig. 9B–E ): pronotal disc ( Fig. 9B ) glabrous, rugose; brown or yellow; anterior margin concave; posterior margin concave, distinctly elevated. Lateral carinae ( Fig. 9C, D ) crenelated, yellow. Lateral lobes ( Fig. 9D ) long and slender, 3× longer than wide, anterior and inferior margin straight, posterior margin widely diagonalized and slightly curved. Tegmina ( Fig. 9E ) truncated; stridulatory vein brown, other veins yellowish, general colour brown.Epimeron II 2× wider than episternum II; epimeron III 1.5× wider than episternum III; episternum II and III and epimeron II and III brownish or yellowish, with dark brown or dark yellow spots. Legs ( Fig. 9A ): all coxae with a blackish spot; all legs dark brown or yellow; tibiae black on ventral margin at apex; three first tarsomeres black on ventral margin and brown dorsally, last tarsomere brownish; femur III slightly longer than body. Abdomen ( Fig. 9A, F, G ): dorsal region dark brown or dark yellow, lateral region light brown or light yellow, with yellow or white spots; traversed by a coloured band, yellow; first abdominal tergite of different colour from general body colour. Tergite X ( Fig. 9F ) with a deep depression on medial region. Subgenital plate ( Fig. 9G ) trapezoidal, 2× longer than wide; styliform processes longer than wide; median keel present in the distal third. Cerci ( Fig. 9F, G ) slightly curved, long and slender, thickness decreasing gradually towards the apical curvature to the dorsal region, with a black apical tooth at apex. Female ( Fig. 14F ): Larger than males. One white strip from eye towards the pronotum. Anterior margin of pronotal disc straight. Tegmina squared, veins evident, darker than general body colour. Abdomen plain coloured, with overall coloration marks as in males. Ovipositor 2× longer than pronotal disc, slightly curved up at base, and acuminate; serrulations beginning on the distal quarter of dorsal valves and distal fifth of ventral valves.
