Abstract

A new species found in northern Thailand and northern India, Waynokiops pentacanthus sp. n., is described based on eggs, larvae, subimagines and imagines of both sexes associated by rearing. A new species from southern India, Waynokiops palifer sp. n. is described based on a mature larva with female subimago and eggs extracted from this larva. All larvae of both species were collected in rivers running in mountain areas. Formerly, the genus Waynokiops Hill et al. 2010 included a single species W. dentatogriphus Hill et al. 2010 known from a few larvae collected in lakes of North America and unknown before 2007. Based on the fact that two newly discovered species of Waynokiops have an Oriental distribution, an assumption is expressed, that W. dentatogriphus is also originally distributed somewhere in the Oriental Region, from where it was introduced into North America. Winged stages are described for Waynokiops for the first time, allowing a more complete generic diagnosis and a better understanding of its systematic position.

摘要

一种新的物种发现于泰国北部和印度北部，即 Waynokiops pentacanthus sp. n.，它是基于饲养时相关的卵、幼虫、亚成虫和两性成虫而描述的。另一种来自印度南部的新物种，即 Waynokiops palifer sp. n.，是基于从一条幼虫中提取的成熟幼虫、雌性亚成虫和卵而描述的。这两个物种的所有幼虫都是在山区河流中采集的。以前，Waynokiops 属 Hill et al. 2010 仅包括一个单一的物种 W. dentatogriphus Hill et al. 2010，已知来自北美的几个湖泊中的少数幼虫，在 2007 年之前不为人知。基于两个新发现的 Waynokiops 物种具有东方分布的事实，可以假设 W. dentatogriphus 最初也分布在东方地区的某个地方，它是从那里被引入北美的。本文首次对 Waynokiops 的有翅阶段进行了描述，这使得对其属的更完整的诊断和对其系统位置的更好理解成为可能。
