This is an account of the cirolanid isopods sampled during 1997, 1998 and 1999 expeditions to subterranean habitats in Mexico and the Bahamas. Seven already described species were sampled, mostly in localities new for them. For Bahalana cardiopus Notenboom found in a cave on Acklins (Bahamas), the differences separating it from the closely related B. geracei CARPENTER are discussed, and the male is for the first time illustrated. The differences between Speocirolana pelaezi (Bolivar) and S. bolivari (Rioja) are once more discussed. Three new species of Speocirolana Bolivar, all from Mexico are described: S. fustiura n. sp. from a cave in Nuevo Leon; S. lapenita n. sp. and S. disparicornis n. sp. from two different karstic springs in Tamaulipas. For a new species from cenotes in Yucatan, a new genus with enigmatic affinities is described: Yucatalana robustispina n. g. n. sp. All newly described species show remarkable morphological features in addition to those generally known as characteristic for subterranean animals - a situation raising questions which should be addressed in the frame of the fundamental inquiry concerning adaptation to life in the subterranean realm.
