缅甸白垩纪琥珀中冥蚁一新种(膜翅目:蚁科:冥蚁族)

A New Species of Hell Ants(Hymenoptera:Formicidae:Haidomyrmecini)from the Cretaceous Burmese Amber

本文描述白垩纪缅甸琥珀中舌冥蚁属Linguamyrmex Barden&Grimaldi一新种,犀舌冥蚁Linguamyrmex rhinocerus sp.nov.,对其形态进行了描述,并附特征图。犀舌冥蚁L.rhinocerus与舌冥蚁L.vladi近似,但该种唇基板长度较舌冥蚁L.vladi长。该种有着特化的"L"形上颚和突出成桨状的唇基,这种奇特的特征在现存蚂蚁类群中已经消失。模式标本保存在华南农业大学昆虫学系标本室。

In this paper a new species of the hell ant,e.g.,Linguamyrmex rhinocerus sp.nov.,from the Cretaceous amber in northern Burma is described and illustrated.The new species is similar to L.vladi,but the clypeal horn of L.rhinocerus is longer than that of L.vladi.Its mandible is L-shaped and clypeal horn is paddle-shaped.These unusual features are disappeared in the current ants.The type specimen is preserved in the Insect Collection in South China Agricultural University.
