Resurrection of Dryotomicus Wood and description of two new species from the Amazon River Basin (Coleoptera, Curculionidae, Scolytinae, Phloeotribini)

A cladistic analysis based on 20 morphological characters was conducted for 11 species representing two valid and two synonymized Phloeotribini genera One hundred-eighty most-parsimonious trees were recovered and the Dryotomicus Wood species were monophyletic in a mostly unresolved strict-consensus tree The unusual antennal morphology, with the length of the first two funicular segments equal to the last three segments and a scape which is twice the length of the funicle, distinguish Dryotomicus from the other Phloeotribini genera Hence this genus is resurrected because of monophyly and diagnostic characters Dryotomicus oenophilis sp n and D woodrex sp n are described from Guyana and Peru, respectively In the male specimen of D oenophilis, the frons has one median and two large lateral carinae and in the male specimen of D woodrex, the frons has three smaller median tubercles arranged transversely Phloeotribus puberulus Chapuis and P tuberculatus (Eggers) were monophyletic with the new Dryotomicus species and thus are transferred to this genus Keys to the Phloeotribini genera and Dryotomicus species are given
