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： Subterranean Biology is an international journal published by Pensoft on behalf of the International Society for Subterranean Biology [SIBIOS-ISSB] for the publication of original and significant contributions on all aspects of subterranean life. The Journal will consider original scientific papers dealing with any aspect of subterranean ecosystems and their components focusing on biology, ecology, evolution and conservation. Reviews and Commentaries: The journal welcomes review articles on aspects of subterranean biology. They should be submitted in the same way as research articles but use a simple layout with no more than three levels of headings. Commentaries on previous matter published in the journal may be also considered. Both reviews and commentaries will be reviewed. Book Reviews: Reviews of books, symposia volumes and conferences pertinent to the journal are welcome. The journal publishes electronic versions of the articles when these are ready to publish, without delays that might be caused by completion of an issue. These electronic versions are not "pre-prints" but final and immutable (Version of Record), hence available for the purposes of biological nomenclature. The date indicated on the electronic version is to be considered the actual publication date.
