Diagnosis

Females of this species can be distinguished from other studied Austrosphecodes by the head, which is larger than the distance between the margins of tegula, and by the presence of 7 to 8 hamuli on the hind wing. Additional features are the T1 mostly impunctate, anterior surface of the mesoscutum sparsely punctate, metapostnotum trapezoidal and deeply concave, and mesoscutum mostly polished among punctures on disc. Males are also distinguished by the same features, except for the not enlarged head.

Etymology

From Greek mythology, the hound of Hades, a multi-headed dog that guards the gates of the Underworld to prevent the dead from leaving. The name is used as a proper noun in apposition.
