Diagnosis. Pronotal prolongation absent, both sexes brachypterous. Tegmina metallic green with no remarkable lobes; general color of thorax and abdomen metallic green with lateral margins of abdominal tergites reddish. Pronotal disc of female with a spot to each side of the prozone (Fig. 82) and subgenital plate tip with a V-shaped cleaving (Fig. 93). Phallic complex: Lateral lobes of epiphallic plate emarginated with medial region of similar width than the epiphallic disc; lateral lobe of epiphallus with anterior margin elongated and posterior margin slightly pronounced (Figs. 71–73).

Holotype: ♂ Colombia, Santander, Virolín [CAUD].

Paratypes: ♂ Colombia Santander Virolín, 1750m, 14 March1981. 2♀ Virolín Finca la Sierra. Road to Málaga km 2 and 6, 900– 1000m, J.L Fernández and C.N Díaz. [UNAB], ♂ Santander, Charalá, 13 May, I. Arévalo. ♀ Encino, 2500m, June 2004, A. Sandoval [MPUJ]. ♀ Colombia, Santander, Virolín [CAUD].

Description. Male. Color in vivo: cephalic capsule light blue, pronotal disc with two slight spots in the anterior margin, bluish green mesozone and metazone, lateral lobes of pronotum light metallic green. Tegmina bright bluish green, yellowish green sternites, tergites metallic green dorsally, reddish in the side; mid part of the tenth tergite and side margins of epiproct dark blue with the remainder of the epiproct whitish blue. Fore legs light red, mid and hind legs olive green. Head. Black antennal segments, scape and pedicel whitish blue. Thorax. Pronotum. Posterior margin of the pronotum truncate, mid line not very notable going from the anterior to the posterior margin of the pronotal disc. Lateral lobes of the pronotum rectangular, moderately wider in the anterior part. Tegmina. Ovoid, covering the second abdominal tergite (Fig. 59). Legs. Hind femora devoid of basal spine, hind tibiae armed in the dorsal margin with 23 external spines of similar size; internal margin with 19 spines, getting bigger from the first through the 7th, and from then a series of alternating short and long spines continue. Abdomen. Mid line of tergites projected all the way to the 9th tergite. Subgenital plate in axial view with a convex tip, triangular epiproct with a slightly pointy tip. Conical cerci, as long as the epiproct and non-curved (Figs. 60–61). Phallic complex. Epiphallus in dorsal view with U-shaped frontal emargination of the epiphallic disc. Lateral lobes of the epiphallic disc emarginated, curving and slender. Hook-shaped lophi, slender and with pointy tip. Endophallic rods not very sclerotized, slender add U-shaped, elongated and connecting with the ectophallic valves. Dorsal disc not very sclerotized, slender and elongated, going from the base of the epiphallus to the base of the ectophallus; ectophallic valves triangular and with a non-curving pointy tip (Figs. 71–73).

Female: Similar to the male in color, except for the following: pronotal spots more notorious and ovoid, wider than long (Fig. 82). All legs olive green. Metazonal region of the pronotal disc not pronounced (Fig. 81). Tegmina covering up to the second abdominal segments, sub ovoid, with no remarkable lobes when compared to the known species of the genus (Fig. 91). Epiproct triangular, with sub-acute tip and conical cerci, tapering noticeably towards the tip and as long as the epiproct length. Ovipositor valves serrated in the dorsal margin of upper valves and in the ventral margin of the lower valves. Last denticule of the valves curved backwards. Subgenital plate with a medialdistal, V-shaped incision (Figs. 92–93).

Etymology. The name refers to the two maculae of the pronotal disc in females and some males.
