Among the eight extant genera of primitively segmented spiders, family Liphistiidae, two are confined to East Asian islands, Kishida, 1923 and Haupt, 1983. In this paper, a taxonomic revision of the genus (Heptathelinae) from Kyushu and Ryukyu archipelago, Japan is provided. This study follows a multi-tier species delimitation strategy within an integrative taxonomic framework that is presented in a parallel paper, in which diagnosable lineages are considered as valid species. There, the initial hypothesis of species diversity (19) based on classical morphological diagnoses is tested with multiple species delimitation methods aimed at resolving conflict in data. This revision follows those analyses that converge on the species diversity of 20, which includes a pair of cryptic species that would have been undetected with morphology alone. After this revision, eight previously described species remain valid, two junior synonyms are proposed, and 12 new species are described based on diagnostic evidence. To ease identification and to hint at putative evolutionary units, is divided into three groups. The Kyushu group contains Haupt, 1983, Ono, 1998, (Kishida, 1920), and Ono, 1998; the Amami group contains Haupt, 1983, Ono, 1996, , , and ; and the Okinawa group contains Haupt, 1983, , , , , , , , , and Tanikawa & Miyashita, 2014 is not assigned to a species group. A combination of diagnostic tools augments the morphological diagnoses that, in isolation, would be prone to error in morphologically challenging groups of organisms.
在原始分节蜘蛛的八个现存属中,六疣蛛科有两个属局限于东亚岛屿(岸田,1923年;豪普特,1983年)。本文对来自日本九州和琉球群岛的(七纺蛛亚科)属进行了分类修订。本研究遵循了在一篇平行论文中提出的综合分类框架内的多层次物种界定策略,其中可诊断的谱系被视为有效物种。在那里,基于经典形态学诊断的物种多样性初始假设(19种)通过多种物种界定方法进行检验,旨在解决数据冲突。本次修订遵循那些收敛于20种物种多样性的分析结果,其中包括一对仅靠形态学无法检测到的隐存种。经过本次修订,八个先前描述的物种仍然有效,提出了两个次异名,并根据诊断证据描述了12个新物种。为便于识别并暗示假定的进化单元,被分为三组。九州组包含豪普特于1983年描述的、小野于1998年描述的、(岸田,1920年)以及小野于1998年描述的;奄美组包含豪普特于1983年描述的、小野于1996年描述的、、、以及;冲绳组包含豪普特于1983年描述的、、、、、、、、、以及。2014年谷川和田下描述的未被归入任何物种组。多种诊断工具的结合增强了形态学诊断,单独的形态学诊断在形态学上具有挑战性的生物类群中容易出错。
