title: Rediscovery of Eremobittacus spinulatus Byers (Mecoptera, Bittacidae) in Mexico, with description of the female and comments on sexual dimorphism and potential mimicry.
abstract: The female of Eremobittacus spinulatus Byers, 1997 is described for the first time. A key to the two species known of this genus endemic to Mexico is provided, and species distribution is illustrated. A case is made for adults of Eremobittacus to be sexually dimorphic, which appears to be an exceptional occurrence in Bittacidae. It is claimed that Eremobittacus spinulatus habitus has a wasp-like appearance, which may potentially depict a case of mimicry.
