Bioacoustics of Neoconocephalus boraceanus

Redescription. Head: Semioval in frontal view ( Fig. 3E, M ); fastigium of vertex trapezoidal in frontal view, two times longer than scapus length, base three times wider than scapus width, tooth weakly projected at basal portion of fastigium ( Fig. 3C, D, E, K, L, M ); fastigium of frons projected, rounded ( Fig. 3E, M ). Thorax: Pronotum anterior margin almost straight, posterior margin slightly convex ( Fig. 3D, L ); lateral lobe as long as wide, anterior margin of lateral lobe straight followed by smooth curve with lower margin almost straight, margin of humeral sinus rounded, invagination of humeral sinus concave ( Fig. 3C, K ). Wings: Tegmen with the basal region weakly narrower than apical region ( Fig. 3B, J ). Legs: Foreleg genicular lobe with rounded apex, tympanum with three distinct regions: proximal one rounded and closed, median one with a pair of open longitudinal slits, and apical one closed, tibia with six pairs of ventral spines; midleg femur with two pairs of small spines, genicular lobe triangular with inner side with acute apex and outer side with apex rounded, tibia with sex pairs of ventral spines; hindleg with femur with 11 pairs of short ventral spines, genicular lobe little developed and slightly curved, tibia dorsally with approximately 22 inner spines and 21 outer spines, in addition to two pairs of spurs, ventrally with nine pairs of small alternating spines. Color : Living specimens mostly green ( Fig. 18C–D ). Specimens studied green with some parts yellow. Type specimens yellow with apical area of wings light green; black on ventral surface of tarsi and frontal area of apex fastigium ( Figs. 3E, M ). Description of male. Tegmen : Stridulatory area with two distinct elevated transverse regions, anterior one oval and posterior one rounded ( Fig. 3F ). Cercus : Dorsal lobe with spine measuring half the length of lobe, ventral lobe two times longer than dorsal lobe ( Figs. 3G, H ). Description of female. Subgenital plate: Posterior margin concave and with a pair of pseudo-styled projections ( Fig. 3N ). Ovipositor: Almost reaching the tegmen apex ( Fig. 3J ). Measurements: Female holotype : BdL 28.1(25.0); FL 1.5; PdL 8.0(8.0); TegL 45.9(44.0); FlegL 8.2; HlegL 25.1(26.3); OvL 28.1(27.0).
