Genus Dicharax Kobelt & Möllendorff, 1900

Charax Benson, 1859: 177.

Dicharax Kobelt & Möllendorff, 1900: 186 . (replacement name for Charax Benson, 1859, non Charax Scopoli, 1777 [Pisces]).

Type species. Alycaeus hebes Benson, 1857 , by subsequent designation ( Gude 1921).

Diagnosis. Typical Dicharax species possess R2 ribs curved toward aperture. Genus generally characterized by complete absence of spiral striation. Only two of 164 species assigned to genus by Páll-Gergely et al. (2020), have indication of spiral striation. A few other species reported to have striations by Jirapatrasilp et al. (2021). Despite occurrence of spiral striations in relatively few species, the absence of striations is generally a valuable character by which to recognize Dicharax species, although examination of additional characters is also critical.
