Diagnosis: the only Patagonian species of Stilobezzia (Acanthohelea)in which males have distal processes of the aedeagus slightly curved and convergent, parameres halves with distal portion broad and rounded tip, and the only females with the anterior margin of sternite 8 straight, at least proximal 2/3 of lateral margins subparallel, posteromedian excavation V-shaped, not heavily sclerotized, and spermathecae heavily sclerotized, with hyaline punctations and short broad necks.
