Morphology of the aedeagus and vagina of and its closely related species were investigated. The internal sac of bears hand saw-like spines, which are arranged in a row. Healing wounds were found on the vagina of this species, whose females were collected in the field during a reproductive season. However, the number of the wounds is low in comparison to the number of the spines. In addition, males of bear one spinous sclerite on the internal sac, but the female of this species show no wounds on the vagina. The vaginal wall is thicker in and in comparison to other studied species, whose males bear no spinous sclerite. This thickening in is hypothesized that they prevent damaging their own internal sac during everting and withdrawing the internal sac with the spines.
对[物种名称]及其近缘物种的阳茎和阴道形态进行了研究。[物种名称]的内囊有手锯状的刺，呈一排排列。在该物种的阴道上发现有愈合的伤口，其雌性个体是在繁殖季节于野外采集的。然而，与刺的数量相比，伤口数量较少。此外，[物种名称]的雄性在内囊上有一个具刺的硬化体，但该物种的雌性阴道上没有伤口。与其他研究物种相比，[物种名称]和[物种名称]的阴道壁更厚，其他物种的雄性没有具刺的硬化体。推测[物种名称]阴道壁增厚是为了在通过刺外翻和缩回内囊时防止损伤自身的内囊。
