脉翅目一新种,Sopogramma liisp。十一月本文对此进行了描述和说明。该新种主要根据其肱回静脉、翅基部中后支之间存在的基底细胞等,归属于Kalligrammatidae的SophogrammaRen。该新种与所有其他Sophogramma种的区别在于翅脉的差异。这个保存异常完好的标本是从位于辽宁省西部北票市附近的黄板鸡沟义县组中发现的。属诊断已根据该新种中显示的新特征进行了修正。根据对Kalligrammatidae所有属和种的产地、分布和地质年代的总结,我们认为Kalligrammatids可能起源于东亚,特别是中国。简要讨论了机翼色素沉着的功能。
A new species of Neuroptera,Sophogramma liisp. nov. is described and illustrated in this paper. This new species is assigned toSophogrammaRen of Kalligrammatidae, mainly based on its humeral recurrent veins, the basal cell present between posterior branch of media at base of wing, etc. The new species is distinguished from all otherSophogrammaspecies on the difference of wing venation. This exceptionally well-preserved specimen is recovered from the Yixian Formation, Huangbanjigou, located near Beipiao City, in western Liaoning Province. The genus diagnosis has been emended based on new characters shown in this new species. Based on a summary of localities, distribution and geological ages of all genera and species of the Kalligrammatidae, we suggest that Kalligrammatids might have originated in Eastern Asia, especially in China. Function of the wing pigmentation is discussed briefly.
