Type material. Female holotype from Jiquilpan (102º41'W, 19º59'N), Michoacan , Mexico, May 9, 1963, W.J. Gertsch & W. Ivie coll., deposited in AMNH.

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Females of Strotarchus michoacan n. sp. resemble those of S. tropicus by the hexagonal atrium, but are easily distinguished by the highly coiled, extremely long, posteriorly enlarged copulatory ducts ( Figs. 116, 117 View FIGURES 114 – 117 ).
