Abstract

The cave-dwelling fauna of Zagros region (Northern Iran) has been insuf ciently studied. Most of the known cave-specialized species (15 out of 21) belong to the genus Schiödte, 1849, yet species composition of this genus is not resolved. In this research, we studied specimens from two recently sampled caves, Shoei and Darvish-Olya Caves, from Kurdistan Province in Iran. The specimens belong to a single, yet undescribed species, which can be diagnosed using mitochondrial (COI) and nuclear sequences (28S rDNA gene sequences) as well as several morphological traits. Based on combined evidence from morphology and molecular characters, we described and named new species, sp. nov.. The newly described species is phylogenetically nested within the clade comprising Iranian species. We provide a new and revised identification key for from the Middle East region.

摘要

扎格罗斯地区(伊朗北部)的洞穴动物群尚未得到充分研究。大多数已知的洞穴特化物种(21种中的15种)属于1849年的Schiödte属,但该属的物种组成尚未确定。在本研究中,我们研究了来自伊朗库尔德斯坦省最近采样的两个洞穴——Shoei洞穴和Darvish - Olya洞穴的标本。这些标本属于一个尚未描述的单一物种,可以通过线粒体(COI)和核序列(28S rDNA基因序列)以及几个形态特征进行诊断。基于形态学和分子特征的综合证据,我们描述并命名了新物种,即sp. nov.。新描述的物种在系统发育上嵌套在包含伊朗物种的进化枝内。我们为中东地区的提供了一个新的修订鉴定检索表。
