Diagnosis. Hind margin of pronotum elongated, surpassing half the length of tegmina and with a pointy tip (Fig. 56). Female tegmina 2-lobed (Fig. 88), subgenital plate of female with medial projection of subgenital plate tip located in a deep emargination as long as lateral projections (Fig. 90). Phallic complex: In dorsal view, epiphallus with frontal epiphallic disc front cleaved in a “V”; lateral lobes of epiphallic disc kidney-shaped and lophi curving outwards. Ectophallus and endophallus as in Figs. 68-70.
Holotype: ♂ Colombia, Cundinamarca, Guayabal de Siquima, Quebrada de San Luis. 1650 m. 4°52'56.79"N, 74°27'54.02"O. 22 May 2011. A. Ardila leg. [CAUD].
Paratypes: 4♂ and 3♀ same data as holotype.
Description. Male. When alive, cephalic capsule blue, pronotal disc (prozona and metazona) dark green, yellow metazona. Anterior margin of pronotum and legs light green. Tegmina metallic green except for the metallic yellow costal and subcostal margin. Abdomen with yellow sternites, tergites olive green with a side yellow strip; 10th tergite, epiproct and cerci dark blue. Head. Antennae with black segments, whitish blue scape and pedicel. Thorax. Pronotum. Posterior margin with pointy tip, going all the way to half of the mesonotum length, dorsal medial line crossing the whole pronotal disc. In side view, pronotum with anterior margin of lateral lobe curving uniformly towards the inferior margin. Distal portion expanding slightly downwards. Tegmina. Ovoid, covering the base of the first abdominal tergite (Fig. 56). Legs. Hind femora devoid of basal spine, hind tibiae armed in the dorsal margin with 25 external, similar sized spines, and 19 in the internal margin, the spines getting bigger in size from the first to the seventh, from then an alternating series of a long and a short spine. Abdomen. Midline of tergites prolonging to the 8th tergite. Subgenital plate in axial view with straight tip, triangular epiproct with a strongly concave tip. Cylindrical cerci, keeping their shape from the base to the tip, going over the epiproct and curving slightly inwards from the mesal portion (Fig. 58). Phallic complex. Epiphallus in dorsal view with Vshaped frontal emargination of the epiphallic disc, lateral lobes of the epiphallic disc kidney-shaped, lophi thickening moderately towards the medial region and curving outwards. Endophallic rods moderately sclerotized and U-shaped, elongated and connecting with the ectophallic valves; dorsal disc elongated and moderately slender, going from the base of epiphallus towards near the tip of the dorsal fold; ectophallic valves triangle-shaped and with a pointy tip that curves slightly downwards (Figs. 68–70).
Female: Color pattern similar to the male (Fig. 108), but body stouter in the thoracic region. Pronotal disc metazone densely porous and projected towards the base of the tenth tergite; metazonal tip pointy (Fig. 79–80). Tegmina covering up to the second abdominal segment, medial lobe with a pointy tip (Fig. 88). Triangular epiproct, rounded tip and conical cerci that do not go beyond the epiproct length. Valves of ovipositor serrated in the dorsal margin of upper valves and in the ventral margin of the lower ones; last denticule of the valves curved backwards. Subgenital plate with tip mid projection located in a deep emargination and as long as the lateral projections (Figs. 89–90).
Etymology. Alluding to the close resemblance to C. insignis.
Measurements (mm). (♂/♀). Lt: 12–12.6 /13.5–14.3; P: 2.7–2.9/ 2.8–3.1; Teg: 1/ 2.5–2.8; HF: 8–8.2/6–7; HT: 10.5–11.2/8.8–9.4.
Comments. Despite the strong resemblance with C. insignis, it is likely that the two females marked as collected in Fusagasugá, Cundinamarca, cited by Hebard in 1933 as C. insignis its can belong to this species, because that pace is closer to the one of the species described herein.
