摘要

描述了产自塔吉克斯坦东部帕米尔山脉的新单型属Pamirosagen.该新属代表了主要属于奥斯特罗拉亚科的 Artoriinae Framenau, 2007 在中亚的首次记录。该属与所有已知的 Artoriinae 属以及所有其他狼蛛属都不同，它具有独特的螺旋状栓皮和附肢，附肢上有其他狼蛛所没有的螺旋状膜质交配导管。该新物种是在海拔 4700 米的石缝中采集到的。与所有其他栖息在石质山麓的古北界狼蛛不同，Pamirosagen.nov.的腿Ⅰ上有四对或更多的腹部胫棘，而Pamirosagen.nov.只有三对。本文提供了该新种的描述、数字、诊断及其栖息地照片。此外，还讨论了亚洲鳞居蜥科的分布情况。

Pamirosa gen. nov., unexpected record of Artoriinae (Araneae, Lycosidae) from the rooftop of Pamir, Central Asia

A new monotypic genus, Pamirosagen. nov. with the type species P. kudratbekovisp. nov. (♂♀), is described from Pamir Mountains in eastern Tajikistan. The new genus represents the first record of the mainly Austrolasian subfamily Artoriinae Framenau, 2007 in Central Asia. It differs from all known genera of Artoriinae, as well as from all other lycosids, by having a unique spiraled embolus and epigyne with screw-shaped membranous copulatory ducts unknown in other wolf spiders. The new species was collected among stone screes at an elevation of 4700 meters. Unlike all other Palaearctic lycosids inhabiting stony screes and possessing four or more pairs of ventral tibial spines on leg I, Pamirosagen. nov. has only three pairs. Description, figures, diagnosis of the new species, and a photograph of its habitat are provided. Additionally, the distribution of scree-dwelling Lycosidae in Asia is discussed.

期刊介绍： Zoosystematics and Evolution, formerly Mitteilungen aus dem Museum für Naturkunde in Berlin, is an international, open access, peer-reviewed life science journal devoted to whole-organism biology. It publishes original research and review articles in the field of Metazoan taxonomy, biosystematics, evolution, morphology, development and biogeography at all taxonomic levels. The journal''s scope encompasses primary information from collection-related research, taxonomic descriptions and discoveries, revisions, annotated type catalogues, aspects of the history of science, and contributions on new methods and principles of systematics. Articles whose main topic is ecology, functional anatomy, physiology, or ethology are only acceptable when of systematic or evolutionary relevance and perspective.
