Identification
Plethochaeta can be distinguished from other Scathophagidae by subtle morphological features of the male genitalia and chaetotaxy (bristle arrangement), though specific diagnostic characters require examination of . The is most readily separated from the widespread genus Scathophaga by differences in the structure of the hypopygium and the arrangement of dorsocentral bristles on the .
