Abstract

In recent years the emphasis of taxonomic studies in many animal groups has been at or near the species level, with often little done to clarify the relationships of the higher taxonomic units. This was either because it was felt that these units needed no revision, or that there was not enough new information at hand to warrant any revision. In many cases, groups of genera have been placed in a family simply because of some superficial resemblance.
