Bioacoustics of Neoconocephalus guyvalerioi

Redescription. Head: Conical in frontal view ( Figs. 8E, N , 9E ); fastigium of vertex trapezoidal in frontal view, two and half times longer than scapus length, base three times wider than scapus width, tooth weakly projected at basal portion of fastigium ( Figs. 8C, D, E, L, M, N , 9C, D, E ); fastigium of frons little projected, rounded ( Figs. 8E, N , 9E ). Thorax: Pronotum anterior margin almost straight and posterior margin almost convex ( Figs. 8A, C, M , 9A, C ); lateral lobe slightly longer than wide, anterior margin of lateral lobe weakly rounded, without evident separation from the lower margin, margin of humeral sinus very rounded, invagination of humeral sinus weakly V-shaped ( Figs. 8C, L , 9C ). Wings: Tegmen with basal and apical region equally wide ( Fig. 8B, K , 9B ). Legs: Foreleg femur with two ventral inner spines inner, genicular lobe triangular and little developed, tympanum with three distinct regions: proximal one circular and closed, median one with a pair of open longitudinal slits, and apical one with open small slit, tibia with six pairs of ventral spines; midleg genicular lobe little developed with inner side with acute apex and outer side with rounded apex, tibia with seven pairs of ventral spines; hindleg femur ventrally with eight inner spines and seven outer spines, tibia dorsally with 29 inner spines and 26 outer spines, ventrally with approximately nine pairs of alternating ventral spines. Color : Holotype mostly light green, additional type specimens ( holotype of N. precarius and holotype of N. matogrossensis ) brown, additional and living specimens green to brown ( Fig. 18E–F ); black on ventral surface of tarsi, tegmen with black spots absent or present. Description of male. Tegmen : Stridulatory area with two distinct slightly elevated transverse regions, anterior one long and posterior one short ( Fig. 8F ). Cercus : Dorsal lobe with spine measuring one third of lobe, ventral lobe two times longer than dorsal lobe ( Fig. 8G, H ). Description of female. Female abdomen: Subgenital plate posterior margin weakly reaching tegmen apex ( Figs. 8K , 9B ). Measurements: Female holotype : BdL 33.2(35.0); FL 2.2; PdL 8.5(8.0); TegL 53.4(52.0); FlegL 7.1; HlegL 26.3(26.0); OvL 29.1(29.0). Female (n=11): BdL 28.1–32.7; FL 2.0–2.3; TegL 48.3–53.1; FlegL 6.7–7.1; HlegL 25.7–27.1; OvL 26.1–28.4.
