  • Abstract:  The subclass Penicillata Latreille, 1829 (= Pselaphognatha Latzel, 1884), sister-group of the Chilognatha (Class Diplopoda), comprises a single order (Polyxenida Lucas, 1840; nomen translatum Chamberlin & Hoffman, 1958) and four families including tiny, hairy, arthropods (up to 7 mm long) characterised by a soft integument and the presence of numerous and specific trichomes covering the head, the trunk segments and the telson. Previous checklists of polyxenid genera have been provided in several books, but these works were devoted to genus and family group-names, including the types of all published names. A new, comprehensive and updated checklist of Penicillata species is proposed as the catalogue for a relational database and taxonomic system of reference for the Penicillata of the world. This review of the currently known world Penicillata comprises 159 valid species and / or subspecies, including one parthenogenetic form, and seven fossil taxa documented from amber. They belong to four accepted families: Hypogexenidae (1 genus), Lophoproctidae (5 genera), Polyxenidae (19 genera), and Synxenidae (1 genus). Three taxa remain incertae sedis. The checklist is documented at the family, genus and species level, and taxa are listed alphabetically. The type-genus of each family and typespecies of each genus are preceded by a bold asterisk. Main synonymies or particular observations are detailed for each valid taxa. The checklist is valid up to May 2003. Penicillata Mundi is a also a relational database maintained at the MNHN (Paris), which aims to provide a tool for monitoring and mapping the biodiversity of Penicillata. In future, the list will be published on a CIM-webpage and then progressively updated. This is part of a project aiming at providing an updated, comprehensive, list of myriapod groups (Diplopoda-Chilognatha, Chilopoda, Pauropoda and Symphyla) on the CIM-website.
