Diagnosis. Rostrum without spots, genicular lobes of hind-femora and external genicular lobe of medium femora unarmed, the remaining armed. Stridulatory crest dilating toward the distal portion, cerci moderately robust, subgenital plate with a “U” shaped notch. Females with straight ovipositor and Sub-genital plate with convex apex, lateral lobes with sub-triangular shape.
Holotype. 1 male. Colombia, Nariño, Barbacoas, Reserva Natural Río Ñambí, 1400 m. 1°17’47.8’’ N – 78°4’29.5’’ W. 1 October 2012. Pinta C. leg. (PSO-CZ).
Paratype. 1 female (PSO-CZ) 1 male Colombia, Nariño, Barbacoas, Reserva Natural Río Ñambi, 1400 m. 1°17’47.8’’ N – 78°4’29.5’’ W. 1 October 2012. Calvache E. leg. (CAUD).
Description. Male. Body slender, general coloration brown (Fig. 19 H). Rostrum light brown without spots; clypeus and post-ocular stripe brown (Fig. 19 C). Ocelli rounded, being the lateral conspicuous and the frontal one reduced. Antennal pedicel with a distal tubercle in the inner margin. Pronotum with abundant granules on its surface, lateral lobes rectangular and wider than long; pronotal regions well defined by sulci; pronotal disc with anterior edge slightly projected forward and rounded posterior edge; humeral sinus slightly developed (Figs. 19 A,B). Meso and metanotum as long as wide; metafurcal groove narrow and deep. Legs: Femora with black spines. Yellow pre-genicular spot in the dorsal surface of hind-femora, not forming a ring as in Eucocconotus. Genicular lobes of hind-femora and external genicular lobe of medium femora unarmed, the remaining armed. Forefemora with four inner-ventral spines; foretibiae with seven spines both in the inner and outer ventral margin. Mid-femora bearing two ventral spines in pre-apex portion; mesotibiae with eight spines on the ventral-external margin and seven spines on the ventral-internal margin. Hind-femora bearing eight ventral spines; hind-tibiae with 10 dorsal-external and 14 dorsal-internal spines. Tegmina with rounded apex and parallel anal and costal margins; stridulatory crest straight with membranous lower area, thickening from anal to distal margin. Tenth tergite slightly convex; epiproctus wider tan long with rounded posterior edge. Cerci cylindrical, moderately robust and tomentose, armed distally with a small spine (Fig. 19 G). Subgenital plate rectangular, longer than wider, “U” shaped distal notch; styli cylindrical and as long as half the length of the subgenital plate (Fig. 19 F).
Female. Of similar shape and size than the male. Legs with the same armature as in the male. Tenth tergite straight; epiproctus wider than long with rounded posterior edge. Cerci cylindrical, tapering in the distal portion. Ovipositor straight and as long as two thirds the length of the posterior femur, with acute apex (Fig. 19 D). Valves gently widened (Fig. 19 E), dorsal valve undulating from the base to the anterior-apical portion and with mesial portion slightly serrated. Subgenital plate as long as wide, tapering towards the apex; distal portion convex and bearing two latero-distal sub-triangular lobes.
Etymology. This new species is named after Awa, an indigenous community that inhabits the area of the Ñambí River Natural Reserve.
Measurements (mm) Ƌ/ ♀: LT: 34/41, LB: 28/34, Pr: 5.5/6, Teg: 28/37, HF: 27/29, HT: 28/30, PS: 5/3.5, Ov: 18.
Comments. This new species has no rostral marks as in Cocconotus carmelitae Hebard, 1927 and C. ecuadoricus (Hebard 1924). Differs from the aforementioned species because of the stridulatory crest notoriously dilated in the distal portion. Specifically differs from C. carmelitae because the head is not globose and possess a post-ocular stripe; additionally, in C. carmelitae males, the styli of the subgenital plate are flattened and wide, and in C. awa n. sp. males, the styli are slender and cylindrical. From C. ecuadoricus it differs in the thicker cerci and wider tegmina; additionally, the ovipositor is straight in C. awa n. sp. females and strongly bends upward from mesal to distal portion in C. ecuadoricus females.
