Pictures of distinctive traits.
Morphologically close genera and how to distinguish them
  • Haetosmia - Osmia
Haetosmia species have very long parapsidal lines, a strongly carinate pronotal lobe and a wide basitarsus on anterior legs.
Osmia species have very short parapsidal lines and no elargement of the basitarsus of the anterior legs.
  • Haetosmia - Hoplitis
Haetosmia species tend to be smaller, they have a strongly carinate pronotal lobe and a wide basitarsus on anterior legs.
Hoplitis species tend to be larger, they have no elargement of the basitarsus of the anterior legs.
  • Haetosmia - Chelostoma & Hofferia
Haetosmia species have long hairs at the apex of the labrum. Scutellum often shorter than the ITD.
Chelostoma & Hofferia species have no long hairs at the apex of the labrum. Scutellum as long or longer than the ITD.
  • Haetosmia - Heriades & Stenoheriades
Haetosmia species don't have a transverse carina on the T1.
Heriades & Stenoheriades species do have a transverse carina on the T1.
  • Haetosmia - Protosmia
Haetosmia species have a vestigial propodeal triangle and a stout body-shape.
Protosmia species have a marked propodeal triangle and a slender body-shape.
General comments on Haetosmia species identification
Females can be diagnosed by the probasitarsus. Males require genitalia and sternites evaluation.
Sorry, but the species identification tool is not yet available for Haetosmia.
