— Ribosomal and ubiquitin protein coding sequence data are generated from 20 arthropods and five close relatives. These molecular data are combined with morphological characters derived from the literature to approach arthropod phylogenetics from the perspective of total evidence. Trilobita were included in the analysis through morphological comparison alone. The overall data strongly support arthropod monophyly. Recent molecular analyses which have yield different results are shown to have been based on few characters, few taxa or both. The most parsimonious explanation of the data is (Annelida + (Onychophora + (Trilobita + Chelicerata) + (Crustacea + (Myriapoda + Hexapoda. The data are largely concordant both internally among data sets and externally with previous cladistic anatomical analyses.
