Abstract

The Pterostichus macrogenys species group is an endemic subterranean Japanese carabid lineage that shows marked regional differentiation, but unresolved taxonomic issues remain, even at the species level. Based on morphological examinations of the genital structures of newly collected specimens and an external morphometric analysis of all the species concerned, P. falcispinus Sasakawa, 2005 syn. nov. is synonymized with P. asahinus Habu & Baba, 1960, and P. awashimaensissp. nov. is described from Awashima Island, a small island off the coast of Honshu. Based on external morphometrics, P. awashimaensis was determined to be most similar to P. yahikosanus Sasakawa, 2009, but its external and genital features differ distinctly from the latter species and it is thought to be more ancestral.

通过外部形态计量学分析和比较生殖器形态揭示了地下甲（鞘翅目，甲科）大翅目物种群中两个物种的身份

大翅目物种群是日本特有的地下甲壳类动物谱系，显示出明显的区域分化，但尚未解决的分类学问题仍然存在，即使是在物种层面。基于对新采集标本生殖器结构的形态学检查和对所有相关物种的外部形态计量学分析，镰刀菌Sasakawa，2005 syn。nov.与P.asahinus-Habu&Baba，1960和P.awashimaensisp同义。nov.是在淡岛描述的，淡岛是本州海岸外的一个小岛。根据外部形态计量学，awashimaensis被确定为与yahikosanus Sasakawa P.2009最相似，但其外部和生殖器特征与后一物种有明显差异，并且被认为更具祖先性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
