SCOLYTIDAE AND PLATYPODIDAE (COLEOPTERA) FROM DOMINICAN-REPUBLIC AMBER

Twenty species of Scolytidae and seven species of Platypodidae are des cribed from fossiliferous amber originating from the Dominican Republi c. The amber is estimated to range in age from 23 to 40 million yr old or Lower Miocene to Upper Eocene. The new species of Platypodidae are Cenocephalus antillicus, C. antiquus, C. biconicus, C. exquisitus, C. senectus, C. spinatus, and Tesserocerus primus. The new genera and sp ecies of Scolytidae are Phloeotribus antiquus, Cladoctonus angustostri atus, C. ruber, Paleosinus (n. gen.) fossulatus, Protosinus (n. gen.) hispaniolensis, Cnemonyx priscus, Scolytus poinari, Pycnarthrum senect um, Micracites (n. gen.) squamifera, Dryomites (n. gen.) incognitus, H ypothenemus avitus, Corthylites (n. gen.) bicolor, Gnathotrichus fosso r, Microcorthylus antiquarius, Paleophthorus (n. gen.) bispinus, Pityo phthorus antiquarius, P. aphelofacies, and P. temporarius. All these s pecies are illustrated here by photographs or line drawings or by both . Types of the three species of Platypodidae described by Schedl (1962 ) from Mexican amber were examined. Notes concerning the type conditio n are given for each species.
