The Dastarcus Group is an informal grouping of Bothrideridae comprising two genera, Dastarcus and Emmaglaeus. Members of this group are unique within the family for having squamiform setae adorning the upper surfaces of the integument. As with most other members of the family, little attention has been given to the morphology and taxonomy of these taxa. The goals of this study are to 1) characterize the morphological diversity within Dastarcus, 2) identify potential characters useful for diagnosing the species within this genus. Specimens of Dastarcus and Emmaglaeus were disarticulated and potential characters were illustrated, photographed and compared across taxa. These data suggest that male genitalia provide a valuable suite of diagnostic characters for Dastarcus species. The nature and distribution of squamiform setae are also diagnostic at the specific level.
