N2  - The stomatopods, or mantis shrimps, are malacostracan crustaceans of the subclass Hoplocarida. Extant hoplocarids belong to the order Stomatopoda and suborder Unipeltata, comprising the extinct, stem-lineage pseudosculdids and sculdids, and the crown group. Cladistic analysis including most or all genera of the unipeltatan families, and rooted to the extinct Tyrannophontidae, resulted in four most-parsimonious cladograms. The present results are more highly resolved and more robust than previous studies as the result of: more precise identification of suitable outgroups; a more complete outgroup data set, lessening the impact of missing data; and increased taxonomic sampling. The results largely support the existing five-superfamily classification, but as with two recent cladistic studies, Gonodactyloidea was polyphyletic. Gonodactyloidea is the basal crown-group superfamily and comprises mostly &#8216;smashers&#8217;. Two clades of &#8216;spearers&#8217;, Eurysquillidae and Parasquillidae, previously considered gonodactyloids, are more closely related to the Squilloidea and are referred to new superfamilies. The familial classification within Lysiosquilloidea is modified. Rather than deriving the &#8216;smashers&#8217; from a long line of &#8216;spearers&#8217;, the present analysis suggests that the Unipeltata diverged in two broad directions from the outset. Hence, the gonodactyloid &#8216;smashers&#8217; became specialised for hard substrates, and the remainder diversified into the other modern superfamilies, evolving more efficient &#8216;spearing&#8217; claws, and occupying soft substrates.
