Abstract

Olindanymphes? headsi sp. nov. (Neuroptera: Nymphidae) is described from the late Aptian (Lower Cretaceous) Crato Formation of Brazil. Its hindwing is unique in the family by the presence of the few-pectinate both CuA and CuP, each with two to three branches. The few-pectinate CuA in the hindwing is a derived condition known only in three Early Cretaceous species, including the new species.

摘要

Olindanymphes? headsi sp. nov.(Neuroptera: Nymphidae)是从巴西晚白垩世(下白垩统)的 Crato 组中描述的。它的后翅因其 CuA 和 CuP 的少量栉状,每个都有两到三个分支而在科内独一无二。后翅的少量栉状 CuA 是一种衍生状态,仅在三个早白垩世物种中出现,包括新物种。
