Habitat
As a member of Trepobatinae, this likely inhabits flowing water such as streams and rivers. Trepobatines are generally associated with lotic (running water) environments rather than lentic (standing water) habitats.
Distribution
Recorded from Middle America and North America. Specific country-level distribution data are not well-documented in available sources.
