First world record of a crustacean (Malacostraca, Bathynellacea) that lives exclusively in groundwater in an unusual habitat, the mesovoid shallow substratum (MSS). The MSS is a terrestrial subterranean medium with high and constant relative humidity. Specimens of the family Parabathynellidae have been found in sampling devices set to collect terrestrial subterranean fauna in the MSS of Sierra de Guadarrama National Park (Madrid, Spain). Two species belonging to two different genera, Hexabathynella nicoleiana Camacho, 1986 and Hexaiberobathynella mateusi (Galhano, 1967), already known to occur in the province of Madrid, have been identified by morphological study, whereas their 18S gene sequences confirmed their generic ascription.

Funding information

This work was funded by the project “Study of the diversity and distribution of the animal species of the Mesovoid Shallow Substratum in enclaves of high Mountain (Sierra de Guadarrama National Park)”, conceded by the Autonomous Organism of National Parks of Spain. Ref. (1143/2014). We would like to thank the staff at the National Park who kindly helped us with the permission applications and other formalities, and to those who also helped us with the fieldwork, especially Patricia Riquelme, Pablo Sanjuanbenito, Juan A. Vielva, Javier Donés, Marisol Redondo, Ignacio Granados, Ángel Rubio, César Martín, José Carrillo, Miguel Ángel Palomar, Ángel Velasco, Germán Mato, Manuel Criado, Enrique Calvo, Federico Madejón, Montserrat Sanz, and forestry agents of Buitrago de Lozoya. Thanks also to our colleagues who collaborated in the design of the samplings and the fieldwork, such as Alberto Jiménez Valverde, Gonzalo Pérez Suárez, Enrique Baquero, Alberto Sendra, Pablo Barranco, Alberto Tinaut, Rafael Jordana, Luis Subías, Juan José Herrero–Borgoñón, Enrique Ledesma, José D. Gilgado, Douglas Zeleppelini and Javier Ledesma. We gratefully acknowledge C. Puch, I. Rey and A. Casado who helped us in different ways and many thanks to Damian Jaume who reviewed the English.
