Morphologically close genera, and how to distinguish them:
Hofferia females have no long setae on the mandible internal margin. Hofferia males do have a preapical transverse carina on S6.
Protosmia species have a propodeal triangle shorter than the metanotum. Females have a labrum with an apical tuft of hairs. In males, T7 is entirely hidden by T6.
Heriades & Stenoheriades species do have a transverse carina between the vertical and horizontal areas of the T1.
Osmia, Hoplitis & Haetosmia species do have long hairs at the apex of the labrum. Scutellum often shorter than the ITD.

General comments on Chelostoma species identification
Females can be diagnosed by the structure on the clypeus apex and labrum, best seen with open mandibles.
Identification criterion in males are located on the last tergites, sternites and genitalia.
