The integumental surfaces of adult Schistosoma incognitum were studied by scanning electron microscopy. The anterior part of the male which bears oral and ventral suckers is spongy in appearance due to the presence of ridges, while the middle and posterior parts are covered with numerous bosses with variable numbers of spines. Surfaces between bosses possess tegumental papillae. Bosses disappear at the edge of the gynecophoral canal which is composed of ridges. They are replaced by variable forms of papillae. The lining of the gynecophoral canal is composed of ridges and papillae, free of spines, with small number of sensory bulbs. The female tegument is relatively smooth and appears to be pitted with minute spines around the oral and ventral suckers. The posterior end of the body, in the vicinity of the excretory pore, is composed of prominent anteriorly directed spines with trabeculae and sensory bulbs.
用扫描电子显微镜对未识别的成年血吸虫的体表进行了研究。雄虫前端有口吸盘和腹吸盘，由于有嵴，外观呈海绵状，而中部和后部则覆盖着许多有不同数量棘刺的瘤。瘤之间的表面有体表乳头。瘤在由嵴组成的抱雌沟边缘消失，取而代之的是各种形式的乳头。抱雌沟的内壁由嵴和乳头组成，无棘刺，有少量感觉球。雌虫体表相对光滑，在口吸盘和腹吸盘周围似乎有微小的刺状凹坑。虫体后端在排泄孔附近，由向前突出的带有小梁和感觉球的棘刺组成。
