I collected this flea along with another of a different species:

on Tree Spring Trl. 281, 8500 ft, Sandia Crest 7.5’ quadrangle in the Sandia Mountains, Bernalillo Co, NM from a Burlese funnel loaded with forest floor detritus collected from under and around a rotting log in a conifer forest. I did not notice a burrow, nest, or midden to suggest its host.

Note this flea lacks a pronotal comb. That should help narrow it down; most fleas have one.
