Genus Pseudotremia Cope 1869

Diagnosis: Distinct from the co-occurring genus Cleidogona in having shoulders on the metazonites of at least the anterior seven segments (in Cleidogona lateral extensions of the metazonites are generally somewhat flattened and paranota-like if they occur at all) and in having the angiocoxites of the gonopods divided into two distinct branches (angiocoxites a single unit in Cleidogona ). The gonopod colpocoxites of Pseudotremia are clasped by a complex of knobs on the coxoprefemora of the ninth legpair (in Cleidogona narrow colpocoxites fit between the coxae of the ninth legpair but are not held by knobs). Pseudotremia ninth leg femora are cylindrical; in Cleidogona they are distally enlarged and nearly triangular in outline. Cleidogona females have a postgenital plate that is never present in Pseudotremia .

Distribution: Appalachian Mountains and Allegany Plateau from Pendleton Co., West Virginia and Bath and Allegany Cos., Virginia southeast to the vicinity of Morgan and Marshall Cos., Alabama and the extreme northwest corner of Georgia (rare in extreme western North Carolina), west through southernmost Ohio and eastern and central Kentucky to southern Indiana and Illinois, thence south to the Nashville Basin in Tennessee ( Shear, 1972; see map in Shear et al. 2007)
