Redescription. Head: Semioval in frontal view ( Fig. 4E ); fastigium of vertex semicircular in frontal view, two times longer than scapus length, base three times wider than scapus width, tooth projected at basal portion of fastigium ( Figs. 4C, D, E ); fastigium of frons little projected, rounded ( Fig. 4E ). Thorax: Pronotum anterior margin almost straight, posterior margin convex ( Fig. 4A ); lateral lobe as wide as long, anterior margin of lateral lobe slightly rounded, without evident separation from lower margin, margin of humeral sinus rounded, invagination of humeral sinus concave ( Fig. 4C ). Wings: Tegmen with basal and apical region equally wide ( Fig. 4B ). Legs: Foreleg genicular lobe with triangular apex, tympanum with three distinct regions: proximal one circular, median one with a pair of open longitudinal slits, and apical one closed, tibia with five ventral spines of inner margin; midleg genicular lobe triangular with inner side with acuminate apex and outer side with rounded apex, tibia with seven pairs of ventral spines; hindleg with femur ventrally with nine inner spines and six outer spines, genicular lobe little developed, tibia dorsally with approximately 21 inner spines and 24 outer spines, ventrally with 11 pairs of alternating spines. Color : Holotype light brown, allotype light green with to yellow; black on ventral surface of tarsi and frontal area of apex fastigium. Description of male. Tegmen : Stridulatory area with single elevated transverse region long and narrow with median furrow throughout length ( Fig. 4F ). Cercus : Dorsal lobe with spine measuring half the length of lobe, ventral lobe two times longer than dorsal lobe ( Figs. 4G, H ). Measurements: Male holotype : BdL 33.8(35.0); FL 1.7; PdL 9.4(9.8); TegL 49.1(50.0); FlegL 8.0; HlegL 28.3(29.5). Male: BdL 26.8; FL 1.7; PdL 8.1; TegL 42.9; FlegL 6.9.

Distribution. Brazil : Mato Grosso do Sul and São Paulo [new record] states . Taxonomic notes. This species is most similar with N. maculosus ( Redtenbacher, 1891 ) and N. spiza Walker & Greenfield, 1983 . However, N. corumbaensis can be distinguished from N. maculosus by the space between fastigium of vertex and fastigium of frons measuring approximately half of scapus length ( Fig. 4C ) (one third of scapus length in N. maculosus ), and from N. spiza by its stridulatory area occupying half the width of tegmen ( Fig. 4F ) (two thirds of tegmen width in N. spiza ). The male allotype of N. boraceanus is herein considered conspecific to the holotype of N. corumbaensis ( Fig. 4J–R ).
