文章题目一种新化石--短毛细鳞蛇Tenuosmylus brevineurus gen.ET sp.11月，采自内蒙古道虎沟村中侏罗世地层露头，中国。根据该亚科的11个特征，该新属被归入Gumillinae。文中还讨论了该亚科5个属的隶属关系。我们的结果支持这样的观点，即Epiosmylinae是Gumillinae的初级异名，基于前翅脉序的相似性，很可能是古代osmylinae的遗迹。MP2和Cu2脉具有复杂的分支，通常存在于灭绝的以及一些现存的亚科中(孔虫亚科、孔虫亚科、狭孔虫亚科)。给出了区分Gumillinae内6个已知属的检索表。
A new fossil lacewing, Tenuosmylus brevineurus gen. et sp. nov., was collected from an outcrop of Middle Jurassic strata in the village of Daohugou, Inner Mongolia, China. The new genus is assigned to Gumillinae based on eleven defining characteristics of the subfamily. The affiliation of Tenuosmylus including other five genera of the subfamily is discussed. Our result supports the opinion that Epiosmylinae was a junior synonym of Gumillinae, which is likely a relic of ancient osmylids based on similarity of forewing venation. Veins Mp2 and Cu2 have complicated branches that are generally present in extinct as well as some extant subfamilies (Poriminae, Eidoporisminae, Stenosmylinae). A key is given to differentiate six known genera within Gumillinae.
