New Pamphiliids with Varying Venations from Lower Cretaceous Yixian Formation of Northeast China (Hymenoptera, Pamphiliidae)
One new genus and three new species of Pamphiliidae, <i>Dolicholyda obtusata</i> gen. et sp. nov., <i>Dolicholyda confluens</i> sp. nov., and <i>Dolicholyda angusta</i> sp. nov. are described and illustrated. All of them were collected from the Lower Cretaceous Yi...

| description | One new genus and three new species of Pamphiliidae, <i>Dolicholyda obtusata</i> gen. et sp. nov., <i>Dolicholyda confluens</i> sp. nov., and <i>Dolicholyda angusta</i> sp. nov. are described and illustrated. All of them were collected from the Lower Cretaceous Yixian Formation in Duolun County, Inner Mongolia, China. The new genus is established based on the following characters: body surface without punctations; forewing with pterostigma lanceolate and sclerotized around the margins; angle between 1-M and 1-Cu nearly 90°; cell 1mcu long and obviously longer than length of pterostigma. In most cases, the ap-Cu is present, and its length varied. Additionally, we revise the diagnostic characteristics of Juralydinae based on the new specimens. New findings enhance our understanding of the wing venation characteristics of fossil pamphiliids and expand the diversity of Pamphiliidae in the Mesozoic. |
