Abstract:
Two new species of cave Collembola, one from each of the genera Typhlogastrura Bonet (Hypogastruridae) and Trogolaphysa Mills (Paronellidae), the first from Mexico and the second from Belize, are described, illustrated and compared with their closest relatives. An additional new record of Heteromurus nitidus (Templeton) from a Mexican cave is given, and a record for Trogolophysa sp. from Guatemala is included.
