Coilodes ovalis – Allsopp 1984: 107 (checklist). — Perk et al. 2002: 14 (checklist). — Ocampo & Ballerio 2006: 191 (checklist). Diagnosis Similar to Coilodes castaneus , it is distinguished by the presence of bigger parameres, longer than half the tegmen size, and by the left paramere apex being not curved.
