Cadena-Castañeda, Oscar J. & Noriega, Jorge Ari, 2015, New Podoscirtine crickets (Orthoptera: Gryllidae; Podoscirtinae) from National Natural Park Amacayacu, Amazonas, Colombia, Zootaxa 3941 (1), pp. 104-116 : 110-112

Aphonomorphus (Nigraphonus) otavoi Cadena-Casteñada, Noriega , n. sp.

( Figs. 23–31 )

Diagnosis. Usual coloration of the subgenus with the exception of legs that are orange. Vein R and R+MA1 delineated with a white color. Subgenital male plate four times longer than wide and softly emarginated in the apex. Phallic complex: da with the apex moderately expanded and the distal spine curved backwards, first pair of ectoparameres almost as long as the second pair of ectoparameres. Ovipositor 1.5 times longer then the hind femur of the females.

Holotype. ♂. Colombia, Amazonas, PNN Amacayacu, ~ 70 m. S. Otavo & J. Noriega leg. (MUD).

Paratype. ♀. Same data as holotype.

Description. Male (holotype). Usual coloration of the subgenus, body predominantly black except legs and palps that are orange and apex of the femurs dark brown, vein R and R+MA1 delineated with a white color, antennas with the flagellomere dark brown and with some white segments. Tomentose body. Subrounded head. Circular and equidistant ocellus, the lateral ocelli bigger than the central one (fig. 23–25). Metanotal gland as fig. 26. Epiproctus simple, narrowing to a narrow and rounded apex, subgenital plate three times longer than the tenth abdominal tergite, apex softly emarginated. Pallic complex: as the subgenus description but with some differences: distal half of genitalia from above m-shaped, da with a form of a tube, projecting progressively forwards, with the apex slightly expanded and spine projected backwards. First pair of ectoparameres (ec), subtriangular and curving itself moderately inwards, apex oblique truncated and with the ventral margin smoothly wave; second pair of ectoparameres (se), curved inwards, longer then ec and with the apex smoothly sharpened; apodemes of endoparamere thin and without later expansions, rami in dorsal view with the expanded mesal portion (figs. 27–29).

Female: Similar to the male in form, coloration, and size. Subgenital plate wider than long and apex softly emarginated. Ovipositor 1.5 times longer then the hind femur, ovipositor apex like in figure 30–31. Measurements (mm) ♂/♀. Total length: 45/46; Pronotum: 3.5; Tegmina: 28/28.5; Hind femur: 18/19; Hind tibia: 19/20; Ovipositor: 25.

Etymology. Dedicated to Samuel Otavo, a renowned biologist and a friend of the second author, who contributed greatly in the sampling of all the specimens described in this paper and achieved all the hard work in the field.
