thick-headed fly
Physoconops nigrimanus is a of in the , first described by Bigot in 1887. Members of this are mimics with elongated resembling . The family Conopidae includes parasitic species that attack and wasps, though specific records for P. nigrimanus are not documented. Observations of this species are extremely rare, with only two records in iNaturalist.

Taxonomic Note
The specific epithet 'nigrimanus' (Latin: 'black-handed') likely refers to dark coloration on the forelegs or a leg-like structure, but original description details require verification.
