Supplementary materials for the manuscript entitled: Mitochondrial Perspective on Species Identification and Delimitation for troglobitic Cicurina (Arachnida: Araneae: Hahniidae) from Central Texas

Central Texas is home to a diverse fauna of endemic species found in the karst areas along the Balcones Fault Line, the Edwards Aquifer region, and associated springs.  The fauna occurring in Bexar County experience especially high anthropogenic pressure due to urban sprawl and suburban development in and around San Antonio, one of the largest cities in the United States.  Among local fauna are numerous troglobitic spider species of the genus Cicurina Menge, 1871 (subgenus Cicurella Chamberlin and Ivie, 1940). Many species of this genus are thought to have small distributions and are often represented in museums and datasets by very few specimens.  Species taxonomy for this group has been defined primarily by differences in the reproductive anatomy of adult females, which are rare in comparison to the number of immature individuals found in the wild.  Prior studies have shown that non-morphologically identifiable immature specimens, in conjunction with adult morphology, aid in illuminat...

德克萨斯州中部的巴尔科恩斯断层线（Balcones Fault Line）沿线喀斯特区域、爱德华兹含水层（Edwards Aquifer）片区及相关联的泉域中，栖息着多样的特有动物类群。贝萨尔县（Bexar County）内的动物类群面临尤为严峻的人为干扰压力，这源于美国最大城市之一圣安东尼奥（San Antonio）城区及其近郊的城市无序扩张与郊区开发活动。本地动物类群中包含隶属于西寇蛛属（Cicurina Menge, 1871）拟寇蛛亚属（Cicurella Chamberlin and Ivie, 1940）的众多洞穴蜘蛛物种。该属的多数物种被认为分布范围狭窄，且在博物馆馆藏与各类数据集里仅留存少量标本。该类群的物种分类学界定主要依据成年雌性个体的生殖解剖结构差异，但野生环境中发现的成年雌性个体数量远少于未成熟个体。既往研究表明，无法通过形态学特征识别的未成熟标本，结合成年个体形态学信息，有助于阐明……（原文未完结）
