Abstract
  • A new genus and species, Bicalcasura maculata gen. n., sp. n. (Coleoptera: Curculionoidea: Dryophthoridae) is described from Dominican amber as the first fossil member of the Tribe Diocalandrini. The new genus is characterized by procoxae located in the middle of the prothorax, a thick, short and strongly curved rostrum with the scape not reaching the pronotum, a weak extension of the rostrum in respect to the antennal attachment, slightly elongated 5th ventrite, narrow (not bilobed) 3rd tarsomere, and a pair of apical spurs on the protibiae. This set of characters separates the fossil from the extant genus Diocalandra Faust, 1894, the only other member of this tribe. A list of weevils (Curculionoidea) described from Dominican amber is included.
