Distribution.

Micromorphus albipes is exceptionally widespread being reported from the Nearctic, Neotropics, Oriental, and Palearctic realms (Pollet et al. 2004).

Remarks.

Robinson (1975) identified this species in Dominica, and specimens from Montserrat match those from Dominica. However, as noted by Pollet et al. (2004), there is some question about whether Zetterstedt’s species is truly so ubiquitous and careful comparison of specimens from each realm is needed. In 2017, adults were obtained by sweeping moist, shaded ground in mesic forests.
