Identification
Nannaria ohionis can be distinguished from other Nannaria by its male , particularly the twisted or curved structure of the telopodite. As with other members of the , identification requires examination of these specialized reproductive appendages. The species is part of a diverse Appalachian and Midwestern radiation of Nannaria, many of which are cryptic and require detailed morphological or molecular analysis to differentiate.

Distribution
Midwestern United States. Confirmed present in Ohio. Distribution records indicate presence in North America, with specific locality data from Ohio.
Behavior
Like other Nannaria , Nannaria ohionis has been observed to remain buried in soil and leaf litter, sometimes staying completely beneath the surface. This cryptic makes specimens difficult to collect.
