Abstract: | The systematic status of the family Calappidae and the phylogenetic relationships of its four component subfamilies are re-evaluated based on a cladistic analysis of 78 adult morphological characters. A single tree was produced (CI = 0.654). The monophyly of the Calappidae sensu lato is rejected. The data suggest that the Calappinae and Hepatinae form a single lineage which is closer to some xanthids than to the Matutinae or Orithyiinae. A close link between the Matutinae and some leucosiids and between the Orithyiinae. and some dorippids is also apparent, with a suggestion that these four taxa all belong to a single lineage. A revised classification of the Oxystomata emend , and Calappidae is proposed. |
