摘要

shuvalikovi Simutnik gen.et sp.nov.是最小的Encyrtidae化石，根据始新世晚期Rovno琥珀的雌性标本进行了描述和说明。与之前描述的大多数始新世羽衣虫科一样，这个新分类单元与大多数现存羽衣虫的不同之处在于尾鳍的近尖位置、前翅相对较长的边缘静脉、明显肿胀但不是三角形的副体毛，以及标记边缘后静脉顶端的刚毛并不比该静脉上的其他刚毛长。这个新属的特征是有一个棘丝和一个远超过合序茎顶端的绒毛。这种性格状态的结合只有在现存的Encyrtinae的少数代表中才为人所知。新属，可能与现存的Aphycus Mayr属关系最密切，1876年。

Protaphycus shuvalikovi Simutnik gen. et sp. nov. (Chalcidoidea, Encyrtidae, Encyrtinae) from Rovno amber

Protaphycus shuvalikovi Simutnik gen. et sp. nov., the smallest fossil Encyrtidae, is described and illustrated based on female specimen from late Eocene Rovno amber. Like most previously described Eocene Encyrtidae, the new taxon differs from the majority of extant encyrtids by the subapical position of the cerci, the relatively long marginal vein of the forewing, a distinctly swollen but not triangular parastigma, and a seta marking the apex of the postmarginal vein is not any longer than others on this vein. The new genus is characterized by the presence of a filum spinosum and the hypopygium reaching way past the apex of syntergum. This combination of the character states is known only in a few representatives of extant Encyrtinae. The new genus, probably, most closely related to the extant genus Aphycus Mayr, 1876.
