Phylogenetic analysis of the Saturnia-group (Saturniidae) of genera based on scolus structure of mature larvae

Abstract

A phylogenetic analysis using final-instar caterpillars of 14 species of Saturniidae was conducted. A total of 22 scoli from 2 thoracic and 4 abdominal segments was categorized according to shape (flat, raised, bulbous) and structure (hairs and spines). Most of the branchings and pairings in the resulting cladogram were supported by previously published classifications. Results support synonymizing Eriogyna under Saturnia (sensu stricto), indicate a close relationship between Eudia and Calosaturnia, and another clade groups Perisomena, Neoris, and Agapema. The genus Caligula as it is currently defined is considered to be polyphyletic.
