Abstract

Rhithrogeniella Ulmer 1939 is treated here as a subgenus of the genus Ecdyonurus Eaton 1868 (s. l.). The subgeneric name Rhithrogeniella is a senior synonym of Afghanurus Demoulin 1964 syn. n., Paracinygmula Bajkova 1975 syn. n. and Nixe Flowers 1980 syn. n. Additional description of Ecdyonurus (Rhithrogeniella) ornatus (Ulmer 1939) is given based on imagines and subimagines of both sexes reared from larvae in India and Thailand; lectotype of this species name is designated. Synonymy of E. (Rh.) ornatus and E. (Rh.) tonkinensis Soldán & Braasch 1986 is established (syn. n.). Male and female imagines and subimagines of an unnamed species of Rhithrogeniella are reported from India.

摘要

本文将 Ulmer 1939 年的 Rhithrogeniella 作为 Ecdyonurus Eaton 1868（s.l.）属的一个亚属来处理。亚属名 Rhithrogeniella 是 Afghanurus Demoulin 1964 syn. n.、Paracinygmula Bajkova 1975 syn. n.和 Nixe Flowers 1980 syn. n.的同义词。根据在印度和泰国饲养的幼虫发育的两性成虫和若虫，对 Ecdyonurus（Rhithrogeniella）ornatus（Ulmer 1939）进行了额外的描述；指定了该种名的模式标本。还确定了 E.（Rh.）ornatus 和 E.（Rh.）tonkinensis Soldán & Braasch 1986 的同义关系（syn. n.）。报道了来自印度的一种未命名的 Rhithrogeniella 物种的雄性和雌性成虫和若虫。
