Cherokia georgiana latassa
Hoffman, 1960
Cherokia georgiana latassa is a of flat-backed millipede originally described by Hoffman in 1960, distinguished by marginal scapulora position and body proportions. Molecular phylogenetic analysis using seven gene loci and delimitation testing has synonymized this subspecies with Cherokia georgiana, demonstrating that morphological characters previously used to define subspecies show clinal variation correlated with geography and elevation rather than phylogenetic structure. The is part of a monospecific to the Appalachian Mountains region of the southeastern United States.

Identification
Originally distinguished from other Cherokia georgiana forms by marginal (versus submarginal) position of the scapulora and specific body proportions. However, these characters have been shown to vary clinally with geography and elevation, and phylogenetic analysis does not support their diagnostic value for -level separation. Coloration is highly variable and does not accord with geography or .
