Uromunna sp. A San Francisco Bay
Uromunna sp. A (Munna) sp., introduced to the San Francisco Bay Delta (Cohen and Carlton 1995; Light et al. 2005; Graening et al. 2012) has not been described in detail, and could be conspecific with U. reyonoldsi.

Uromunna spec. Netherlands
Uromunna spec. Netherlands is a new introduction there. It is morphologically distinct from U. reynoldsi and U. hayesi, from the East and Gulf Coasts of North America (Faasse and Ligthart 2013).
