Abstract
Ramageopteraplatycephala gen. et sp. nov., a new protopristocerine wasp, is described and figured from a female individual preserved in mid-Cretaceous amber from Tanai, northern Myanmar. Ramageopteraplatycephala gen. et sp. nov. shows most of the known characters used to circumscribe the extinct subfamily Protopristocerinae, and highlights the putative status of stem-Pristocerinae that may occupy the Protopristocerinae. Ramageopteraplatycephala gen. et sp. nov. is unique among the Protopristocerinae, at least, for possessing a flat and square shaped head; eyes glabrous and small; mandibles with four conspicuous sharp teeth; antenna with short scape; forewing with Rs + M vein absent; vein M straight; cell 2R1 distally opened; cell 1Cu closed, sub-equal to R cell; cell 2Cu open.
在缅甸北部塔奈发现的中白垩世琥珀中，发现了一种新的原始原始黄蜂——Ramageoptera platycephala gen. et sp. nov.。Ramageoptera platycephala gen. et sp. 11 .显示了大部分已知的特征，用于划定已灭绝的原猿亚科，并强调了可能占据原猿亚科的干猿亚科的假定地位。至少在原始鸟科中，有一个扁平的方形头是独一无二的;眼睛无毛和小;下颌骨有四颗明显的尖牙;具有短柱面的天线;前翼无Rs + M脉;脉M直;2R1细胞远端打开;单元1Cu闭合，次等于R单元;2Cu单元打开。
