ABSTRACT

The nomenclature of Scymnus quadrillum Motschulsky 1858 (nec Redtenbacher 1843), S. latemaculatus Motschulsky 1858, and Scymnus (Clitostethus) fumatus Sicard 1929, all originally described from Ceylon, is discussed and clarified. Based on examination of material at the Natural History Museum, London, identified by comparison with Motschulsky’s lectotypes, Scymnus (Pullus) coccivora Ayyar, 1925, an economically important species widely distributed in the Indian region, is found to be conspecific with S. quadrillum. As S. quadrillum is a junior primary homonym of S. quadrillum Redtenbacher, 1843, S. coccivora, the next seniormost available name, should be applied for this species. Scymnus latemaculatus Motschulsky, 1858 is the correct name of the species commonly and widely distributed in the Oriental region, Middle East and Africa and identified as S. quadrillum auctt., Scymnus (Pullus) taiwanus Ohta, and Scymnus (Pullus) belophallus Capra by various authors. Scymnus (Pullus) elegans v. clathratus Sicard, 1929, currently regarded as a synonym of S. coccivora, is conspecific and synonymous with S. latemaculatus (syn. nov.) and is removed from synonymy with S. coccivora. A lectotype is designated for S. latemaculatus. Scymnus (Clitostethus) fumatus Sicard, 1929 is transferred to Axinoscymnus Sasaji (comb. nov.), briefly redescribed and illustrated.

摘要

讨论并阐明了最初由锡兰描述的四眼Sc麦草（Symymus quadrillum Motschulsky 1858）（nec Redtenbacher 1843），S。Latemaculatus Motschulsky 1858和Scymnus（Clitostethus）fumatus Sicard 1929的命名法。基于在自然历史博物馆，伦敦，与天牛的选模式比较确定的材料检查，Scymnus（Pullus）coccivora Ayyar，1925年，在经济上重要的物种广泛分布在印度地区，被认为是同种与S. quadrillum。由于S.quadrillum是S. quadrillum Redtenbacher，1843，S. coccivora，未来seniormost可用名称，应适用于这一物种。Scymnus latemaculatus Motschulsky，1858年是该物种的正确名称，该物种在东方地区，中东和非洲普遍且广泛分布，并被各种物种标识为S. quadrillum auctt。，Symymus（Pluus）taiwanus Ohta和Scymnus（Pulus）belophallus Capra。作者。Scymnus（Pullus）elegans诉clathratus Sicard，1929年，目前被认为是S. coccivora，是同种的，并用同义S. latemaculatus（顺式。11月的），并从与同义除去S. coccivora。为S. latemaculatus指定一个选型。Scymnus（Clitostethus）fumatus Sicard，1929年被转让给Axinoscymnus Sasaji（梳子。nov。），简要地进行了重新描述和说明。
