Diagnosis

This species has the T1 mostly impunctate, the anterior surface of the mesoscutum not rugulose, and the metapostnotum trapezoidal. It is similar in size to A. cerberus sp. nov. and A. tartarus sp. nov. but the head is not enlarged and the mesoscutum is not sulcate. Differently from A. asmodeus sp. nov. the body length is more than 7 mm, the anterior surface of the mesoscutum is sparsely punctate (i=pd), the scutellum has a well-defined longitudinal row of punctures, and the terga are lineolate.

Variation

Variation in body size was found in females, from 7.0 mm to 8.5 mm (the holotype).

Etymology

From Greek mythology, grim, dreadful creature. The name is used as a proper noun in apposition.
