Identification
Agaricomorpha can be distinguished from other Gyrophaenina by subtle characters of the mouthparts, tarsal formula, and male genitalia. Accurate identification to level requires examination of microscopic features and is generally not possible from field observations alone. The genus is most reliably identified by through dissection and comparison with .
