Taxonomic notes. It was described originally as a species in a distinct genus Leptodampius. No other specimens were recorded and the species was only rarely cited by subsequent authors (Kevan 1983; Mercurio 2010), without reassessing its taxonomic position. It is assigned here to Strigamia for the first time (new combination), because it shares all major diagnostic features of Strigamia (see above under “Notes on taxonomy”). Its actual distinction from other species is uncertain, as the original description is incomplete in many characters.
Distribution: known from a single locality in the northern Coast Ranges, Oregon.
