A new crane fly species is reported from western Michigan. Adults of Tricyphona (Pentacyphona) michiganensis Taber appear in late summer in the bracken fern understory of aspen-birch-red maple forest. The most remarkable feature of the new species is the wing of the female, which is not reduced like that of its presumably closest relative Tricyphona (Pentacyphona) autumnalis Alexander, but of a length similar to that of the male and sometimes longer. Additional characteristics of both sexes distinguish this crane fly from its consubgeners, most of which are restricted to the southwestern and western United States.
