Abstract
Twenty-two species of Lymaenon Walker (Hymenoptera: Mymaridae) from China are keyed; illustrations, taxonomic and other notes are also provided for some of these taxa. Six species are newly described: L. funiculus Aishan & Hu sp. n., L. ledongus Aishan & Hu sp. n., L. longitus Aishan & Hu sp. n., L. naiquanlini Aishan & Hu sp. n., L. radiculus Aishan & Hu sp. n., and L. zhui Aishan & Hu sp. n., all from the Oriental part of the country. Eleven species are newly recorded from China: L. bashai (Zeya), L. berijamus (Mani & Saraswat), L. breviterebratus (Subba Rao), L. delhiensis Narayanan & Subba Rao, L. katraps (Triapitsyn), L. kazak (Triapitsyn), L. krasavchik (Triapitsyn), L. longior (Soyka), L. narayani Subba Rao & Kaur, L. sundus (Zeya & Anwar), and L. tamilanus (Mani & Saraswat).
