利用X射线显微计算机断层扫描、光学显微镜和扫描电子显微镜，详细描述了两种mantophasmatodean物种，Karoophasma biedouwense和Viridiphasma clanwilleyense的雌性内部生殖解剖。我们确定了成对的卵巢包含panoistic卵巢管，受精囊周围的上皮细胞的腺结构，以及受精囊管周围的肌肉细胞。管状附腺，这是目前在许多昆虫，是失踪的整个女性生殖道的heelwalkers。因此，我们认为，包括在上皮细胞的腹侧生殖室的heelwalkers产生的分泌物用于建设卵荚中的鸡蛋和沙子粘在一起。这两个物种的调查不同的卵巢的数量，每个卵巢和受精囊的形状。这项研究增加了对mantophasmatodean内生殖器的稀缺信息，并为进一步研究足跟步行者的生殖行为提供了基础。
The female internal reproductive anatomy of two mantophasmatodean species, Karoophasma biedouwense and Viridiphasma clanwilliamense, is described in detail using X-ray micro-computed tomography, light microscopy, and scanning electron microscopy. We identified paired ovaries containing panoistic ovarioles, a spermatheca surrounded by an epithelium of glandular structure, together with a spermathecal duct surrounded by muscle cells. Tubular accessory glands, which are present in many insects, are missing throughout the female genital tract of heelwalkers. Therefore, we suggest that the gland cells included in the epithelium of the ventral genital chamber of heelwalkers produce the secretions used for building egg pods in which eggs and sand are glued together. The two species investigated differ in the number of ovarioles per ovary and in the shape of their spermatheca. This investigation adds to the scarce information on mantophasmatodean internal genitalia and provides a basis for further research on reproductive behavior in heelwalkers.
