Abstract

Three new species of the genus Solenysa Simon, 1894 are recorded and described from Western Japan, all based on both sexes. Of these, two species are endemic to the Ryukyu Archipelago: S.shimatchu Ballarin & Eguchi, sp. nov. from Amami-Ōshima Island, and S.yambaruensis Ballarin & Eguchi, sp. nov. from Okinawa Honto and Kume-jima Islands. These species represent the first record of the genus Solenysa for the Central Ryukyus and belong to a newly defined species group. Another new species, S.bilamellata Ballarin & Eguchi, sp. nov. is recorded from eastern Kyushu in mainland Japan and belongs to the mellotteei group. The phylogenetic positions of the new species are discussed based on morphological and molecular data. New records, remarks, and photos of genitalia of other poorly known Solenysa species from surrounding areas (Taiwan, Kyushu, Shikoku, and western Honshu) are provided to facilitate future identifications.

蜘蛛属Review， 1894年在日本西部和琉球中部，附有三新种的描述（蜘蛛目，蜘蛛科）。

1894年在日本西部记录和描述了三种新属，均基于两性。其中两种是琉球群岛特有的：来自奄美-Ōshima岛的S.shimatchu Ballarin & Eguchi, sp. 11 .和来自冲绳本户岛和久米岛的S.yambaruensis Ballarin & Eguchi, sp. 11 .。这些物种代表了中琉球岛螺线绳属的首次记录，属于一个新定义的物种群。另一新种，S.bilamellata Ballarin & Eguchi, sp. nov，记录于日本大陆九州东部，属于mellotteei组。根据形态学和分子数据，讨论了新种的系统发育位置。本文提供了周边地区（台湾、九州、四国和本州西部）其他不为人知的Solenysa种的生殖器官的新记录、注释和照片，以方便今后的鉴定。
