Etymology. This species is named in honor of Saint Sarah Kali the patron saint of the Roma people, whose source word “Kali” in Sanskrit means "blackness" in reference to the dark color of this species. Comments. This species is most similar to Coelinius acontia (Riegel, 1982). It differs by having frons rugulose (acontia, shining, weakly punctate); antenna with more than 43 segments (acontia, 34 segmented); propodeum rugose, basally with a median longitudinal carina (acontia, rugulose, lacking median carina); T1 rugulose (acontia, evenly rugulose); ovipositor without spines at apex (acontia, bearing stout spines at apex). |
