One species, Tricharaea (Sarcophagula) occidua, has been documented as abundant in faunal studies of coastal Buenos Aires, Argentina, where it comprised a significant portion of flesh fly encounters. Species-level identification within this genus requires examination of male genitalia due to uniform external chaetotaxy.

Taxonomic Note
The Tricharaea occidua has been treated under the subgeneric name Sarcophagula (as Tricharaea (Sarcophagula) occidua) in some literature. No comprehensive key for identifying Neotropical of Sarcophagidae currently exists, making generic and species assignments difficult without examination of male terminalia.
