چکیده انگلیسی
Mesozoic leiodids are poorly known, and only one definitive leiodid is formally described from Burmese amber. Here we describe and illustrate the second definitive Mesozoic leiodid, Cretagyrtodes glabratus gen. et sp. nov., based on a single specimen from the Upper Cretaceous Burmese amber. The fossil is placed in Agyrtodini (subfamily Camiarinae) after maxillary palpomere 4 as wide as palpomere 3, and procoxal cavities closed behind. Cretagyrtodes is tentatively attributed to the extant “Eupelates group”. The discovery of Cretagyrtodes in Burmese amber suggests that the south hemisphere endemic tribe Agyrtodini is probably an ancient group, which has showed its first appearance before the breakup of Pangaea.
