Title

Oplophoridae (Decapoda: Crustacea): phylogeny, taxonomy and evolution studied by a combination of morphological and molecular methods

Abstract

The first comprehensive phylogenetic study of the family Oplophoridae is based on four molecular markers and 87 morphological characters. We have examined and coded five major groups of morphological characters related to the rostrum (nine characters), the carapace (10), the abdomen and telson (34), the exopods (eight) and the armature of the posteriormost three pereopods (22). Abdomen/telson-linked characters are the most important in support of genus level and species-group level clades; abdomen/telson-linked, rostrum-linked characters and the armature of the last three pereopods explain the main bulk of speciation. Four robustly supported species groups within Systellaspis are designated: the S. debilis species group, the S. cristata species group, the S. braueri species group and the S. pellucida species group. We provide an amended key to all genera, species groups and species of Oplophoridae. We reveal three groups of morphological characters, which are likely coupled with the same locomotive function and thus evolved as a single unit: carapace, abdomen and exopods. We show that the armature of the posteriormost three pereopods evolved independently of other characters and suggest that this group is linked to such biological roles as mating and grooming.
