Morphology‐based phylogenetic reconstruction of Cholevinae (Coleoptera: Leiodidae): a new view on higher‐level relationships

Abstract The current state of knowledge of the suprageneric relationships in Cholevinae is either derived from informal evaluations of putative synapomorphies or based on molecular studies with limited taxonomic sampling. Here we assessed the higher‐level relationships in this subfamily based on a phylogenetic analysis of 97 morphological characters scored for 93 terminals, representing all tribes. Both parsimony and Bayesian analyses were used. The monophyletic origin of Cholevinae was corroborated, except for the unexpected inclusion of Leptinus in the implied weighting analysis. Eucatopini + Oritocatopini were retrieved as basal branches in the evolution of Cholevinae. The monophyletic origin of all remaining Cholevinae was confirmed, which is consistent with molecular evidence. Anemadini was non‐monophyletic, in accordance with earlier hypotheses. Cholevini was rendered non‐monophyletic by the uncertain inclusion of Prionochaeta and the consistent exclusion of Cholevinus . A close affinity of Ptomaphagini to Sciaphyini and Leptodirini was suggested, although the position of Sciaphyes remains uncertain. The phylogenetic hypothesis of Cholevinae provided here is the most comprehensive presently available. The list of characters shows that a substantial part of the data was obtained from the ventral side. This is a strong argument for a detailed pictorial documentation of the ventral body parts in taxonomic descriptions, in contrast to the common practice of only illustrating the dorsal habitus of the beetles.
