A cladistic analysis of the genera of the family ‘Lafoeidae’ was performed in order to investigate suprageneric classifications and the boundaries of the family, as well as to organise the available morphological data and discuss the possible evolution of some morphological characters. Our results suggest that the former ‘Lafoeidae’ must be separated into two families: the Hebellidae and the Lafoeidae (including the subfamilies Lafoeinae and Zygophylacinae).


The authors wish to thank Professor Wim Vervoort (Nationaal Natuurhistorisch Museum, Leiden, The Netherlands) for his help with the bibliography, Dr A. M. García-Carrascosa (Universidad de Valencia, Spain) for accommodating us in his laboratory for part of the studies, Dr Peter Schuchert (Museum d’Histoire Naturelle, Geneve, Switzerland) for his comments on a previous version of the manuscript, and to Dale R. Calder (Royal Ontario Museum, Canada) and an anonymous referee for their valuable suggestions. We also acknowledge the staff of the museums listed in Table 3 for the loan of species. The project had financial support from Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP 2001/02626-7, 2001/10677-0, 2003/02432-3, and 2004/09961-4), Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq 471960/2004-7), National Museum of Natural History, Department of Invertebrate Zoology, United States Antarctic Program funded by the National Science Foundation (OPP-9509761), from the Ministerio de Educación y Ciencia of Spain and the Fondo Europeo de Desarrollo Regional (FEDER) (CGL2004-04684/ANT), and from the National Science Foundation (EF-0531779).
