Three new genera and species of Cenomanian Cixiidae from Kachin amber (Myanmar) are described: Acrotiara Bourgoin & Luo gen. nov., type species A. multigranulata Luo & Bourgoin sp. nov., Delphitiara Bourgoin & Luo gen. nov., type species D. tibiocoronata Luo & Bourgoin sp. nov., and Pentacarinus Bourgoin & Luo gen. nov., type species P. kachinensis Luo & Bourgoin sp. nov. A key to identification of these new genera is provided. These cixiids with a pentacarinated mesonotum belong to a new tribe Acrotiarini Bourgoin & Luo trib. nov., type genus Acrotiara gen. nov., which is characterized by a specific set of characters, some being unique in the family Cixiidae such as the paired sublaterofrontal carinae and the arched RA on the tegmina. This new taxon prompts discussion of the current classification and phylogeny of the family, which remains widely unexplored, and of the evaluation of the placement of two older cixiid fossils currently known, Karebodopoides aptianus (Fennah, 1987) and Cixius petrinus Fennah, 1961. A new genus, Barremixius Bourgoin & Szwedo gen. nov., is proposed for the latter, resulting in the new combination Barremixius petrinus (Fennah, 1987). Karebodopoides Szwedo, 2001 and Barremixius gen. nov. are provisionally recognized as the oldest Cixiidae, respectively representative of the oecleinian lineage (including Bothriocerini trib. stat. nov.) and of the cixiinian lineage. Acrotiarini trib. nov. belongs to the pentastirinian lineage (including Borysthenini stat. nov.). All these fossils depict that the first main division that occurred in Cixiidae, occurred much earlier during the Cretaceous

阿克罗蒂亚里尼部落。11月,在缅甸北部白垩纪中期琥珀的慈溪科(昆虫纲,半翅目,狐形目)中,对科的分类有了新的见解

描述了来自克钦琥珀(缅甸)的 Cenomanian Cixiidae 的三个新属和种:Acrotiara Bourgoin & Luogen。11 月,类型种A. multigranulata罗 & Bourgoin sp。十一月Delphitiara Bourgoin & Luo gen。11 月,类型种D. tibiocoronata Luo & Bourgoin sp。11 月,和Pentacarinus Bourgoin & Luo gen。11 月,类型种P. kachinensis Luo 和 Bourgoin sp。十一月 提供了识别这些新属的关键。这些带有五角化介孔的慈溪属于一个新的部落 Acrotiarini Bourgoin & Luo 部落。十一月,类型属Acrotiara将军 nov.,其特征在于一组特定的字符,其中一些在慈溪科中是独一无二的,例如成对的副侧额隆突和 tegmina 上的拱形 RA。这个新的分类群促使人们讨论该科目前的分类和系统发育,该科的分类和系统发育仍未得到广泛探索,以及对目前已知的两种较古老慈鲷化石的位置的评估,即Karebodopoides aptianus(Fennah,1987 年)和Cixius petrinus Fennah,1961 年。新属,Barremixius Bourgoin & Szwedo gen。11 月,为后者提出,导致新组合Barremixius petrinus (Fennah, 1987)。Karebodopoides Szwedo, 2001 和Barremixius将军 十一月 暂时被认为是最古老的慈溪科,分别代表 oecleinian 谱系(包括 Bothriocerini trib. stat. nov.)和慈溪科。阿克罗蒂亚里尼部落。十一月 属于pentastirinian谱系(包括Borysthenini stat. nov.)。所有这些化石都表明慈溪科的第一次主要分裂发生在白垩纪
