Abstract. The phylogeny of two heterogeneous Indo-West Pacific and African sesarmid genera, Chiromantes Gistel, 1848, and Pseudosesarma Serène & Soh, 1970, is investigated using morphological and molecular methods. The two genera look superficially very similar, lack stridulatory ridges and tubercles on the chela, and have previously been separated by the presence or absence of an epibranchial tooth on the lateral margin of the carapace. Related members of Bresedium Serène & Soh, 1970, Sesarmops Serène & Soh, 1970, and allied genera are included in this revision. The analyses reveal a complex evolutionary history with numerous monophyletic clades supported by consistent morphological apomorphies. These clades are here described as nine new genera for which diagnoses are given and the constituent species described, figured, and compared. Two new species of a new genus are also described from Indonesian Papua and Papua New Guinea. This revision is a major step in the process of establishing a taxonomic system taking into account monophyletic units within the Sesarmidae.
