The earliest fossil record of Phloeocharinae, Angucharcotes thayerae gen. et sp. nov., is reported from mid-Cretaceous Burmese amber. Angucharcotes shares characters with both Phloeocharis-related and Charhyphus-related lineages (e.g., mesoventrite with a median longitudinal carina, temple relatively long, basal tarsomeres unexpanded, pronotal and elytral margins crenulate/serrate, mesocoxae contiguous). The abruptly angulate temples of Angucharcotes are unique in Phloeocharinae. Our discovery of Phloeocharinae from mid-Cretaceous highlights the antiquity of this subfamily.

缅甸北部白垩纪中期琥珀中的Phloeocharinae的最早化石记录(鞘翅目:Staphylinidae)

最早的Phloeocharinae化石记录,Angucharcotes thayerae gen。等人。据报道,产自白垩纪中期缅甸琥珀。AngucharcotesPhloeocharis相关和Charhyphus相关谱系具有共同的特征(例如,具有中位纵向隆突的中腹,太阳穴相对较长,基底节肢节未扩张,前胸和鞘翅边缘具圆齿/锯齿,中壳相连)。Angucharcotes突然成角的寺庙在Phloeocharinae中是独一无二的。我们从白垩纪中期发现的 Phloeocharinae 突出了这个亚科的古代。
