Remarks. This species was described based on a single specimen collected in Cochabamba, Bolivia by P. Germain and deposited in MNHN.

According to Sൺඇඍඈඌ-Sංඅඏൺ +| Mൺඋඍංඇඌ (2010) (translated): ‘Some differences pointed out by Mൺඋඍංඇඌ +| Gൺඅංඅൾඈ (2001), to separate C. argodi from C. soledari , are variable in the former: legs black except for the base of profemora and the joints of all the tibiae that are yellowish; head, prothorax and the apical third of elytra are black, without metallic reflections. In fact, legs can be entirely dark brown or yellowish (including most surface) with dark areas, and head, prothorax and the apical third of elytra may be metallic with violaceous reflections.’ The only reliable difference between C. argodi and C. soledari appears to be the presence of dark maculae on sides close to the epipleural margin in the former, which is absent in the latter. It is very probable that these two nominal taxa are synonyms.

We observed chromatic variations as follows: anterior dark macula of elytra distinctly widened from the basal quarter to about middle. In addition, we present here description of male terminalia: Tergite VIII ( Fig. 51 ) with distal margin curved and lined with short and some long yellow setae, mainly medially. Sternite VIII ( Fig. 52 , broken during the dissecting process) transverse; apophysis long, about three times as long as sternite. Ventral arc ( Fig. 53 ) fork-shaped, with apophysis short, arms curved. Dorsal arc was not found in the dissected specimen. Tegmen ( Figs 57–59 ) about 0.8 times length of median lobe; distal region completely divided into parameres; parameres cylindrical-elongated, ornate with erect short yellowish setae, apex rounded and bearing both short and long setae; ring piece elongated, proximal part connected only by narrow membrane, without projection. Median lobe ( Figs 60–62 ) notably curved in lateral view; dorsal lobe with apex rounded and not reaching curved apex of ventral lobe; basal apophysis about ⅔ length of apical region.
