A new genus and species, Bicalcasura maculata n. gen., n. sp. (Coleoptera: Curculionoidea: Rhynchophorinae: Dryophthoridae) is described from Dominican amber as the first fossil member of the Tribe Diocalandrini. The new genus is characterised 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 fifth ventrite; narrow (not bilobed) third 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.
