Bombus insularis
Hi, John. My doubt is whether this is insularis, previously reported from Canada and the US. Following the descriptions from Mitchel (1962) I thought this could be insularis, based on the presence of yellow pile on the metasomal terga, which is not presnte in variabilis. What do you think?

 
insularis is a northern/montane species
unknown in Mexico to my knowledge

The only Psithyrus possible in Veracruz is B. variabilis sensu lato

Bumble bee species routinely vary a great deal in color across their ranges, and it is unwise to rely on Mitchell when dealing with the Veracruz fauna. Check the following revision instead:

Labougle, J.M. 1990. Bombus of México and Central America (Hymenoptera, Apidae). Univ. Kansas Sci. Bull. 54: 33-73

This looks like B. variabilis (sensu lato)
not B. insularis

The name Bombus intrudens Smith has been applied to B. variabilis (sensu lato) from Veracruz.
