Abstract
A new tribe, Mekorhamphini trib. n., two new genera Mekorhamphus gen. n. and Habropezus gen. n. and two new species ( M . gyralommus sp. n. and H . plaisiommus sp. n.) are described from Burmese amber. The new tribe resembles the tribe Mesophyletini but differs from the latter by possessing contiguous procoxal cavities and very wide elytra with regular striae. From the tribe Anchineini, it differs by the contiguous procoxal cavities, precoxal portion of the prosternum elongated, and swollen trochanters. The new taxa can be distinguished from modern Carini by having antennae attached near the middle of the rostrum, an elongated precoxal portion of the prosternum and enlarged trochanters.

ABSTRACTAn ambrosia beetle described as Palaeotylus femoralis n. gen et sp. belonging to a new subfamily (Palaeotylinae n. subfam.: Coleoptera: Platypodidae) is described from Cretaceous Burmese amber. It differs from other subfamilies by the loose antennal club, 6-articled funicle, coarsely faceted eyes, tibiae with teeth at apex, bilobed meso- and meta-tarsomeres 2 and 3 and tarsomere 1 shorter than tarsomeres 2–4 combined. This is the first described Platypodidae from Burmese amber and the ol...

Only a few weevils have been described from Burmese amber, and although most have been misclassified, they show unusual and specialised characters unknown in extant weevils. In this paper, we present the results of a study of a much larger and more diverse selection of Burmese amber weevils. We prepared all amber blocks to maximise visibility of structures and examined these with high-magnification light microscopy as well as CT scanning (selected specimens). We redescribe most previously descri...
