Abstract

Allochthonius (Urochthonius) yoshizawaisp. nov., found in Hiura-do Cave, a limestone cave located in the municipality of Kumakogen, Ehime Prefecture, Japan, is described. It can be distinguished from the consubgeneric species mainly by the carapacal chaetotaxy (6–2, 18), by the presence of 6 setae on the cheliceral palm, by the rallum with 11 blades, by the presence of 8 clavate coxal blades on coxae I, and by the decreased number and distinct shape of the chelal teeth. A redescription of the subgenus Urochthonius, and keys to the subgenera of Allochthonius and to the species and subspecies of Urochthonius are also provided, as well as some ecological remarks, a brief discussion on troglomorphisms for the subgenus, and potential threats for this species.

日本拟蝎亚属(拟蝎科，拟虎蝎科)一新种

异齿龙（Urochthonius）Yoshizawasp。11月，在日本爱媛县久马根市的一个石灰岩洞穴Hiura do洞穴中发现。它与同属物种的区别主要是：背甲毛状体（6-2，18），螯掌上有6个刚毛，有11个叶片的平行体，第一节有8个棍棒状的舵手叶片，以及螯齿数量减少和形状不同。文中还对乌罗希通亚属进行了重新描述，并对其亚属、种和亚种进行了检索，同时还对一些生态学问题进行了评述，简要讨论了该亚属的同源性，以及对该物种的潜在威胁。

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.
