Diagnosis

Externally almost indistinguishable from S. parasordipes sp. nov. but differs as follows: male S5 with a very large medial pale area, dark lateral lines almost reaching anterior margin (cf. Marshall 1995: fig. 9); surstylus with a convex anterobasal edge (cf. Marshall 1995: figs 1–3); postgonite narrowly constricted without an anterolateral lobe in the apical third (cf. Marshall 1995: fig. 5).

Distribution

Nearctic: Canada, United States of America.

Remarks

Sclerocoelus sordipes is externally very similar to S. parasordipes sp. nov. (from western North America), from which it differs only in the features described above. Females of these two species are indistinguishable externally and were associated with conspecific males on the basis of collecting localities. Sclerocoelus sordipes is a common eastern Nearctic species, found from Manitoba to Nova Scotia and south to Georgia. We have collected it most often on moist decaying plant material, including lawn clippings and leaf piles in forested areas.
