记述了采自西伯利亚北方Yantardakh地区晚白垩世（Santonian）泰梅尔琥珀中的Prosienina sphinga sp. nov.。根据下颚须、后翅脉M和横脉1 r-m的特征状态以及胫骨假距的缺失，初步将该新种归属于白垩纪的该属。然而，肋空间的结构和后翅的RP分支表明它可能属于一个新的，密切相关的属。这第二个物种在当地的发现可能表明，西西里德通常是北方西伯利亚的Santonian河岸生物群落的成员。(C)2016爱思唯尔有限公司版权所有
Prosisyrina sphinga sp. nov. (Neuroptera: Sisyridae) is described from Upper Cretaceous (Santonian) Taimyr amber of northern Siberia (Yantardakh locality). The new species is preliminary assigned to this Cretaceous genus, mainly based on character states of the maxillary palpus and the hind wing vein M and crossvein 1r-m, and the presumable absence of tibial false spurs. However, the structure of the costal space and the RP branching in the hind wing indicate that it may belong to a new, closely related genus. The discovery of this second species from the locality might suggest that sisyrids were usual members of the Santonian riparian biocenoses of northern Siberia. (C) 2016 Elsevier Ltd.
