Neoconocephalus karollenkoi Piza, 1983 View in CoL . Piza Jr. (1983): 112 [Description]; Otte (1997): 59 [Catalog]; Chamorro-Rengifo & Braun (2010): 43 [Catalog].

Type locality. Serra do Navio , Amapá, Brazil .

Diagnosis. Robust body, being the largest neotropical species ( Fig. 14A, B View FIGURE 14 ); head conical in frontal view ( Fig. 14E View FIGURE 14 ); fastigium of vertex trapezoidal in frontal view, three and half times longer than scapus length, base three times wider than scapus width ( Fig. 14E View FIGURE 14 ); lateral lobe of pronotum as long as wide ( Fig. 14C View FIGURE 14 ); and wing apex rounded ( Fig. 14A, B View FIGURE 14 ).

Redescription. Head: Conical in frontal view ( Fig. 14E View FIGURE 14 ); fastigium of vertex trapezoidal in frontal view, three and a half times longer than scapus length, base three times wider than scapus width, tooth weakly projected at basal portion of fastigium ( Fig. 14C, D, E View FIGURE 14 ); fastigium of frons little projected, rounded ( Fig. 14E View FIGURE 14 ). Thorax: Pronotum anterior margin almost straight and posterior margin almost convex ( Figs. 14A, D View FIGURE 14 ); lateral lobe as long as wide, anterior margin of lateral lobe almost straight, followed by a smooth curve with lower margin almost straight, margin of humeral sinus rounded, invagination of humeral sinus concave ( Figs. 14C View FIGURE 14 ). Wings: Tegmen with basal region slightly larger than apical region ( Figs. 14B View FIGURE 14 ). Legs: Foreleg femur with two ventral spines, 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 a small open slit, tibia with six pairs of ventral spines; midleg femur with four ventral spines, genicular lobe triangular with inner side with acute apex and outer side with rounded apex, tibia with six pairs of ventral spines; hindleg femur with three spines, tibia dorsally with 20 inner spines and 22 outer spines, ventrally with seven pairs of spines. Color : Type specimen mostly brownish yellow, some parts of tegmen green; black on ventral surface of tarsi and ventral margin of the fastigium of vertex.

Description of female. Subgenital plate: Posterior margin concave with two triangular projections ( Figs. 14F View FIGURE 14 ). Ovipositor: extending beyond tegmen apex ( Figs. 14B View FIGURE 14 ).

Measurements: Female holotype: BdL 34.4(36.0); FL 3.6(3.5); PdL 7.7(8.0); TegL 58.4(48.0); FlegL 8.1; HlegL 26.4(25.0); OvL 39.1(37.0). Females (n=2): BdL 33.1–34.7; FL 3.3–3.5; PdL 7.4–8.0; TegL 55.4–57.3; FlegL 7.9–8.1; HlegL 26.0–27.4; OvL 37.8–40.2.

Distribution. Brazil: Amapá and Pará [new record] states.

Taxonomic notes. This species is most similar with N. colorificus ( Walker, 1869) , N. nigromaculatus ( Redtenbacher, 1891) , and N. truncatirostris ( Redtenbacher, 1891) . However, N. karollenkoi can be distinguished from N. colorificus by fastigium of vertex thicker and straight ( Fig. 14C, D, E View FIGURE 14 ) (thinner and slightly curved apex in N. colorificus ) and from N. truncatirostris and N. nigromaculatus by tooth at fastigium base weakly projected ( Fig. 14C View FIGURE 14 ) (developed and downcurved in N. truncatirostris and N. nigromaculatus ).
