Distinguished from other Amphizoa species by the structure of the front tarsi: A. striata has a well-developed groove on the posterior surface of the front tarsi with grooves bearing long hair-like setae. The species is also geographically restricted to the Pacific Northwest, separating it from other North American Amphizoa species with different ranges.

Cold, fast-flowing trout streams. The species is associated with lotic freshwater environments in forested regions of the Pacific Northwest.

Western North America: British Columbia (Canada), Oregon, and Washington (United States).
