Paleotrichius dominicanus n. gen., n. sp. (Coleoptera; Cetoniidae), a flower beetle in Dominican amber

摘要

A new genus and species of flower beetle, Paleotrichius dominicanus, n. gen., n. sp. (Coleoptera: Cetoniidae: Trichinae) is described from Dominican amber. The new taxon is distinguished from all other New World trichines by the combination of the shape of the clypeus, pronotum, protibia, the femoral and tibial armature, the mesosternal process separating the middle coxae, the distinct strial pattern on the elytra and the approximate claws. The beetle may have been quite colourful and a strong flyer attracted to flowers. The larvae most likely developed in decaying hardwoods in the Dominican amber forest. This is the first amber representative of the family Cetoniidae.
