Bryoplana xerophila, a new genus and species of limnoterrestrial protoplanelline platyhelminth, was found in moss and soil covering a concrete wall in northern Alabama, USA. Bryoplana xerophila is the first taxon of limnoterrestrial Protoplanellinae recorded from North America and is one of the few rhabdocoels known from dry habitats. It is unique within Protoplanellinae in lacking rhabdites, having a pharynx rosulatus in the frontal half of the body, and lacking sclerotized parts in the male system. Notes on encystment, reproduction and feeding behavior are given. An updated identification key to all known genera of Protoplanellinae is presented. © 2010 Zoological Society of Japan.
