Immature stages of Euchirinae (Coleoptera: Scarabaeoidea): genera Cheirotonus and Propomacrus with comments on their phylogeny based on larval and adult characters
2011
Abstrakt
We report the discovery of the larvae of Propomacrus bimucronatus (Pallas, 1781) in their natural habitat; providing notes on their biology based on field observations and laboratory-bred specimens. We give a detailed description of Cheirotonus formosanus Ohaus, 1913 and P. cypriacus Alexis et Markis, 2002 larvae as well as a redescription of the immature stages of P. bimucronatus and present the first diagnosis of larval Euchirinae.
Based on 105 morphological and ecological characters of adults and larvae in 24 taxa of Scarabaeoidea, we discuss the phylogenetic relationships of Euchirinae within the group.
