Abstract
  • A new genus and species of bostrichid, Discoclavata dominicana n. gen., n. sp., (Coleoptera: Bostrichidae) and a new genus and species of eucnemid, Lissantauga epicrana n. gen., n. sp. (Coleoptera: Eucnemidae) are described from Dominican amber. Diagnostic characters of Discoclavata dominicana include an extended body, strongly hypognathous head, asparate dorsal surfaces of pronotum and elytra, 10 antennomeres with a large, oval two-articled club, flattened and grooved metafemora that receive the flatted metatibia, 5-segmented, slender tarsi with the first tarsomere miniscule, 2nd, 3rd and 4th tarsomeres small, subequal and fifth tarsomere longer than the others combined. Diagnostic characters of Lissantauga epicrana include a glabrous, silvery metallic body, pectinate antennae with the antennal insertions positioned below the eyes, a helmet-shaped pronotum with the anterior angles nearly reaching the antennal insertions, the antennae close to the eyes, angled apical margins of the elytra and a long first tarsomere. These are the first descriptions of Bostrichidae and Eucnemidae from Dominican amber.
