The present study reports on nine new tanaidomorph species from eight different genera from this material. These include representatives of genera known elsewhere from non-vent-associated deep-sea habitats, but notably only the second and third (respectively) representatives of two genera, Coa-lecerotanais and Cristatotanais, known previously from cold-seep-habitats in the Gulf of Mexico. The genus Spinitanaop-sis is synonymized with Cristatotanais. The tanaidacean records to date from hydrothermal vents or cold seeps are collated as a context for the present material. Thepossibilities of habitat-endemism in tanaidacean taxa associated with reducing environments and their biogeography are discussed.

Three of these species are habitually found in springs: Lirceus brachyurus, Caecidotea kenki, and C. alleghenyensis, n. sp. The latter, described herein, is a member of the hobbsi group known only from the Allegheny Mountains in Garrett Co. Six species are obligate inhabitants of subterranean waters and are found primarily in Appalachian caves, although some have broad ranges that span non-cavernous areas. The obligate subterranean species are Caecidotea pricei, C. franzi, C. holsingeri, C. mausi, C. vandeli and C. nordeni.

After examining type and related specimens at museums in the USA and UK, we have determined thespecies is new to science. It is herein named Tucetona isabellae. In our description we use morphological characteristics outlined in Tschudin (2001) and Squires (2010).
