within Cionopsis can be distinguished from one another primarily by the pattern of sculpturing on the : C. crispula has wavy (crispate) sculpturing, C. echinata has spiny (echinulate) projections, C. lineola has linear markings, and C. maculata has spotted () patterns. The can be recognized as by the presence of an elongated (snout) with mouthparts at the tip, (elbowed) , and a compact body form typical of . Specific generic-level diagnostic features require examination of genitalic and other internal characters.
Distribution
The has been recorded from the Neotropical region, with distributions corresponding to the localities of their original descriptions. Cionopsis palliatus, the type species, was described from Mexico. The other four species were described from specimens collected in Central America and Mexico.
