Remarks. This species is similar to Clytrovorus suarezi Móczár, 1984 by having the head longer than wide; the median clypeal lobe angulate, with clypeal carina inclined in profile; the mesoscutum and scutellum short; the scutellar groove narrow and arched; the propodeal disc without longitudinal ridge between median and inner discal carina; the mesopleural sulcus foveolate; brachypterous. However C. bara sp. nov. has the frons sparsely foveolate; the pronotum with anterior margin with transverse carina; the longitudinal pronotal furrow present; the propodeal disc with lateral carina absent, with the posterior carina not failed medially; the posterior spine of propodeum present, whereas C. suarezi has the frons coriaceous; the pronotum with anterior margin without transverse carina; the longitudinal pronotal furrow absent; the propodeal disc with lateral carina present, with the posterior carina failed medially; the posterior spine of propodeum absent.
