本文报道了在中白垩世缅甸琥珀中发现的两种蚤类，Latempheria kachinensis Li，Yoshizawa，and Yao，gen. et sp. nov.和Burmempheria curvatavena Li，Yoshizawa，and Yao，sp. nov.被描述并分配到Empheriidae（Trogiomorpha：Atropetae）家庭。根据3个外群和15个内群的38个形态特征，对Atropetae下目进行了系统发育分析，支持Atropetae包括化石和现存类群的单系性。在系统发育结果中，所有属的化石科Empheriidae和Archaeatropidae形成一个单系群，姐妹的Atropetae现存成员。这两个化石家族在形态、地点和地质时期上也有许多相似之处。最近发现的化石种具有两科的综合形态特征。根据这些观察和系统发育分析的结果，古壶螺科被认为是一个新的小异名。
Two species of psocids discovered from the Mid-Cretaceous Burmese amber, Latempheria kachinensis Li, Yoshizawa, and Yao, gen. et sp. nov. and Burmempheria curvatavena Li, Yoshizawa, and Yao, sp. nov., are described and assigned to the Empheriidae (Trogiomorpha: Atropetae) family. A phylogenetic analysis of the infraorder Atropetae is conducted based on 38 morphological characters of three outgroups and fifteen ingroups, which supported the monophyly of Atropetae including fossil and extant taxa. In the phylogenetic result, all the genera of fossil families Empheriidae and Archaeatropidae form a monophyletic group, sister to the extant members of Atropetae. The two fossil families also share a lot of similarities in morphology, locality, and geological period. Recently discovered fossil species exhibited combined morphological characters of both families. Based on these observations and the results of the phylogenetic analysis, Archaeatropidae is treated here as a new junior synonym of Empheriidae.
