Type species: Zauxieus toxopeusi Viette, 1952 by original designation. Diagnosis. Among Hepialidae Elhamma species are readily recognised by the unique hind-wing venation where only two M-veins are present. Males are furthermore recognised by the deeply cup-shaped juxta which at least in part appears to accommodate the prominent posterior projection of S8.
