Typhlichthys subterraneus  Girard 1859 (in part)




12 syntypes as histological preparations (Charlton 1933) and specimens (whereabouts now unknown). Shown to be an available name by Parenti (2006).

The specific name eigenmanni was used by Niemiller et al. (2012) for for Ozark Highland populations that are disjunct from the rest of the distribution of Typhlichthys subterraneus.


Recorded from 35 caves in Missouri (15 confirmed by molecular data) and 5 caves in Arkansas (3 confirmed by molecular data) (Niemiller et al. 2013).

Conservation Status
