Morphology of bromeliad-associated immature stages of Daiphron bipartitus and its adults confirms the non-monophyly of the genus (Coleoptera: Cantharidae)

Abstract

Daiphron bipartitus Pic, 1934 is a poorly known species whose systematic position in the subfamily Chaulioganthinae is still controversial. In this paper we describe immature stages of,which were found inhabiting fallen bromeliads,in southeastern Brazilian Atlantic forest. Adults are redescribed, including the first study of male and female genitalia. Larva, pupa and adult are illustrated in detail and compared with other species of,Gorham, 1881 and,Hentz, 1830. We discuss the systematic position of,within Chauliognathinae on the basis of morphological comparison of its immature and adult characters. Both were found to be more similar to species of,than to,Pic, 1949, which supports the hypothesis of polyphyly of,. Aspects of the species biology and occasional association with bromeliads are discussed.
