Mordellistena fuscata (Melsheimer, 1845)
tibia, 4 ridges, tarsi #1, 3 ridges, tarsi #2, 2 ridges. Dark brown, densely dull golden pubescent. (1)
Liljeblad's monograph casts some doubt on this species, at least regarding the valid type speciman. "seems probable that it resembles very closely a female of M. ambusta LeConte, which also has a rather strong rudimentary fourth ridge on the posterior tibiae."
