Abstract

A new genus and species of Sisyridae, , is described from the Late Cretaceous (earliest Cenomanian/late Albian) Myanmar amber. It can be easily distinguished from other sisyrids genera by the configuration of wing venation such as forewing with four ra-rp crossveins, M forked distal to the separation of RP1, CuA pectinate and CuP simple; hind wing 1r-m long and sinuous. Besides, the newly documented spongillaflies bore distinct, irregularly distributed spots on the forewings.

摘要

一种新的毛翅目昆虫的属和种，被描述于白垩纪晚期（最早的赛诺曼阶/晚阿尔比阶）的缅甸琥珀中。它可以通过翅脉的形态与其他毛翅目昆虫属轻易区分开来，比如前翅有四条径横脉，M脉在RP1脉分离点的远侧分叉，CuA脉栉齿状且CuP脉单一；后翅1r-m脉长且弯曲。此外，新记录的水蛉在前翅上有明显的、分布不规则的斑点。
