Phylogeny and classification of the tribe Calopterini (Coleoptera, Lycidae)

Abstract

AbstractThe phylogeny of lycid tribe Calopterini is examined in the light of adult morphological evidence. Representatives from each of the Calopterini genus - group taxa and genera Dictyoptera, Lygistopterus, Conderis, Plateros, and Lycus are examined. An investigation of Calopterini phylogeny is presented here, based on 33 characters and 24 supraspecific terminal taxa, representing genera whose monophyly was implicitly assumed. Four cladistic analyses were performed with equal and successive weights and multistate characters treated as additive and non-additive, respectively. The preferred hypothesis, a strict consensus tree generated using successive weighting and unordered characters yields the scheme of relationships (Eurrhacina + (Calopterina + (Cyrtopteron + Mesopteron + Falsocaenia + Acroleptina))). On the basis of these results, two new subtribes Eurrhacina and Acroleptina are proposed.
