Abstract

A broad-nosed weevil, Promecops tumidirostris n. sp. (Eudiagogini: Curculionidae), and a false ladybird beetle, Nilio dominicana n. sp. (Nilionini: Nilionidae), are described from Dominican amber. P. tumidirostris can be distinguished from extant species by the greatly swollen apical portion of its rostrum, large eyes almost meeting on top of its head and a V-shaped suture separating the first and second abdominal sternites. N. dominicana differs from extant species by its small size and 18 elytral striae with small interstrial punctures. Neither tribe is represented in Hispaniola today, supporting earlier studies showing a greater biodiversity in the region during the mid-Tertiary than at present.
