Type-species. Nannaria minor Chamberlin 1918a , by original designation.

Remarks. Nannaria occurs from westcentral New York and southeastern Virginia to western Ohio and perhaps eastcentral Kentucky / Tennessee and northern Alabama / Georgia, and presently comprises 17 species. However, N. ericacea and N. scutellaria , for example, do not seem congeneric with N. minor and appear to require new genera, and numerous new and undiscovered species and genera undoubtedly await discovery in both the field and preserved holdings. A revision is needed but can only derive as part of a comprehensive tribal review, which is well beyond our scope. We note, however, that the holotypes of the two most important components – N. minor , the type-species, and N. oblonga , the oldest name and thus holding priority over all others – have never been illustrated, and knowledge of their gonopods is essential for generic and tribal revisions to advance. We therefore publish such ( Fig. 24–25 ) to eliminate this void and facilitate future research.
