The order Raphidioptera, particularly the family Raphidiidae, is a rare insect group from China. In the present paper, Xanthostigma xanthostigma(Schummel, 1832) of Raphidiidae is newly recorded in China. The Chinese species of the genus Xanthostigma are redescribed and illustrated, with updated information of their geographical distributions.
The family Dipteromantispidae, previously with only two genera and three species, is one of the enigmatic groups of the Cretaceous Neuroptera by the mantispid-like appearance combined with strongly reduced hind wings specialized into a haltere-like structure. A new genus and species of Dipteromantispidae, namely Halteriomantispa grimaldii gen. et sp. nov., is herein described based on an exquisitely preserved specimen from the mid-Cretaceous amber of northern Myanmar. It represents the first record of Dipteromantispidae from the amber deposit of mid-Cretaceous(Albian-Cenomanian) of Myanmar. A brief discussion on the homology of forewing venations and female genital sclerites of Dipteromantispidae is given.
