 The taxonomy of the genus is somewhat confusing, as many of the species within it are poorly studied and are found only in very restricted ranges, or deep within caverns.Several species have even been described several times by different researchers, and some are often considered to be morphologically different enough to warrant being placed into their own genera.A recent taxonomic revision moved the Georgia blind salamander to this genus, which makes "Haideotriton" a synonym of "Eurycea".
