中文摘要：

回顾近年来所发现的与我国三叶虫有关的11个晚出同名属及其替代名的研究现状,详细报导最近新发现的37个晚出同名三叶虫属中的13个属及其替代名。这些属涉及到寒武纪,奧陶纪,志留纪和泥盆纪的三叶虫。此外,河南龙Honania Young,1979（模式种H.complicidentata Young,1979）是产于河南济源晚二叠世爬行类锯齿龙科的一个属,由于晚于三叶虫河南虫HonaniaLee in Luet al.,1963（模式种H.lata Lee in Luet al.,1963）所建,成为无效属名,建议将河南龙的属名更名为钟键龙（新属）Zhongjiania gen.nov.。

英文摘要：

Recently 37 junior homonyms of trilobite ge-nera have been found （zdikmen,2006,2009）,of which 13 trilobite genera have been recorded in China,e. g.,Acanthocephalus Qiu in Qiu et al.,1983,Aethia Qian and Zhou,1984,Ariaspis Wolfart,1974,Cavia Sun,1994,Coronaspis Wu,1990,Drepanura Bergeron,1899,Haasia Yuan,1988,Hospes Stubblefield in Stubblefield and Bulman,1927,Lobopyge Pribyl and Erben,1952,Madygenia Petrunina in Repina et al.,1975,Mareda Kobayashi,1942,Pionaspis Zhang in Qiu et al.,1983,Pseudophalacroma Pokrovskaya,1958. The senior homonym of Acanthocephalus Qiu in Qiu et al.,1983 is Acanthocephalus Koelreuter,1771,with A. anguillae （Mller） as the type species,therefore,the replacement name for the Acanthocephalus Qiu in Qiu et al.,1983 is Proacanthocephalus zdikmen,2008. The genus Aethia Qian and Zhou,1984 is preoccupied by Aethia Merrem,1788,with A. cristatella （Pallas,1769） as the type species. The replacement name for Aethia Qian and Zhou,1984 is Paleoaethia zdikmen,2008. The senior homonym of Ariaspis Wolfart,1974 is Ariaspis Denison,1963,with Ariaspis ornata Denison,1963 as the type species. The replacement name for the Aria-spis Wolfart,1974 is Karslanus zdikmen,2009. It occurs in central Afganistan and in Hubei and southeastern Sichuan,South China. The senior homonym of Cavia Sun,1994 is Cavia Pallas,1766,with C. porcellus （Linnaeus,1758） as the type species,however invalid name Cavia Sun,1994 and their replacement name Sunocavia zdikmen,2009 are considered as synonymous with Haniwa Kobayashi,1933. Coronaspis Wu,1990 is preoccupied by Coronaspis MacGillivray,1921,with Chionaspis coronifera Green,1905 as the type species. Coronaspis Wu,1990 was suppressed as a junior synonym of Coronocephalus Grabau,1924 （Lin,2008）,however it differs from the Coronocephalus Grabau,1924 mainly in having a much higher elevated posteriorly located palpebral lobe,the presence of narrower pygidiual border and wider pleural field of pygidium,therefore the repalcement name Wuoaspis zdikmen
