A new genus and new species of Nymphidae (Neuroptera) is described from the Ypresian Okanagan Highlands locality of Falkland, British Columbia, Canada: Epinesydrion falklandensisnew genus, new species. This is only the fourth known Cenozoic adult specimen, and all others are less complete. It is the second specimen from the Okanagan Highlands. Currently Nymphidae has two recognised subfamilies. All Cenozoic fossils are confident members of the Nymphinae, but the subfamily assignments of almost all Mesozoic genera are problematic. The Late Cretaceous Dactylomyius is the only genus that might belong to Myiodactylinae. The rest may belong to the undefined stem groups of the family or to the Nymphinae, with varying levels of probability. Mesonymphes sibirica is transferred to Nymphites Haase: N. sibiricus (Ponomarenko), new combination; Sialium minor to Spilonymphes Shi, Winterton, and Ren: Spilonymphes minor (Shi, Winterton, and Ren), new combination; “Mesonymphes” apicalis does not belong to Mesonymphes Carpenter and may not even belong to the Nymphidae. The fossil record of the family occurs across much of the globe, but today they are restricted to Australia, New Guinea, and possibly the Philippines. Modern Nymphinae is only found in Australia. This may result from a requirement of frost-free climates, which were more widespread in the past.

从加拿大不列颠哥伦比亚省福克兰的伊普尔人Okanagan高地地区描述了一种新的y科属和新种：Epinesydrion falklandensis新属，新种。这只是第四次已知的新生代成年标本，其他所有的都不太完整。这是来自Okanagan高地的第二个标本。目前，y科有两个公认的亚科。所有新生代化石都是are虫的有力成员，但是几乎所有中生代的亚科都存在问题。白垩纪晚期的Dactylomyius是唯一可能属于Miodactylylinae的属。其余的可能属于该家族未定义的茎类或若虫，具有不同的可能性。西伯利亚转移到Nymphites Haase：N. sibiricus（Ponomarenko），新的组合；Sialium轻微到Spilonymphes时，温特顿，和仁：Spilonymphes未成年人（施，温特顿，和仁），新组合; “ Mesonymphes ” apicalis不属于Mesonymphes木匠甚至可能不属于belong科。该家庭的化石记录遍及全球，但是今天，它们仅限于澳大利亚，新几内亚，甚至菲律宾。仅在澳大利亚发现了现代N虫。这可能是由于过去无霜气候的要求所致。
