Key to the identification of Sarcofahrtiopsis spp. (males only)

Modified from Pape and Méndez (2004) and Carvalho-Filho etal. (2014).

Females are notincluded inthis keysincethey areunknown formost of the species. Sarcofahrtiopsisdiembroma Dodge, 1965 was not included because only the female is known.
