摘要

The systematic status of geographical variants of Arcuphantes hibanus Saito, 1992 belonging to the A. longiscapus species group, indigenous to western Honshu and Shikoku, Japan, was evaluated using morphological and molecular data. Two species, A. enmusubi Ihara, Nakano and Tomikawa, sp. nov. and A. occidentalis Ihara, Nakano and Tomikawa, sp. nov., are described, and A. hibanus is redescribed with redefinition of its taxonomic status. These three species are diagnosed by the characteristics of paracymbium, pseudolamella, and epigynal basal part. Phylogenetic trees obtained with mitochondrial cytochrome c oxidase subunit I and 16S rRNA markers showed that the variants are mutually genetically highly diverged. However, the mtDNA phylogenies failed to recover the monophyly of A. hibanus redefined herein. Contrary to the mtDNA phylogenetic analyses, a neighbor-network analysis of nuclear internal transcribed spacer 1 sequences of A. hibanus, A. enmusubi and A. occidentalis spiders showed that each of them forms a cluster. The results of mitochondrial and nuclear DNA analyses in each of the three species are briefly discussed, along with their taxonomic identities.

Hibanus被重新定义了其分类地位。这三种物种被帕拉基铵，假瘤率和外膜基底部分的特征诊断出来。用线粒体细胞色素C氧化酶I和16S rRNA标记获得的系统发育树表明该变体具有相互遗传高度分散。然而，MTDNA文学未能在本文重新定义的HIBANU中未能恢复。与MTDNA系统发育分析相反，核内部转录间隔物1序列的邻网络分析A. Hibanus，A. Enmusubi和A. occidentalis蜘蛛表明它们中的每一个都形成群集。简要讨论了三种种类中的每一个的线粒体和核DNA分析结果以及其分类物理标识。
