Intestinal ciliates excreted in the feces of Asian elephants were surveyed. Fourteen species in the order Entodiniomorphida were detected. Nine Triplumaria species in the family Cycloposthiidae were found. Using the silver impregnation, two known species, T. antis and T. dvoinosi, were redescribed and six new species, T. sukuna n. sp., T. zuze n. sp., T. solea n. sp., T. suwako n. sp., T. fulgora n. sp., and T. harpagonis n. sp., were described. T. sukuna, T. zuze, T. solea, and T. suwako have the perivestibular polybrachykinety along the vestibular opening. The buccal infraciliary bands of T. suwako are similar to those of T. selenica found from elephants and the buccal infraciliary bands of T. sukuna, T. zuze, and T. solea are similar to those of T. grypoclunis described from rhinoceroses. T. antis, T. dvoinosi, T. fulgora, and T. harpagonis have the vestibular polybrachykinety extending down inside the vestibulum as found in rumen ciliates in the family Ophryoscolecidae. The caudalial ciliary zones of T. dvoinosi and T. fulgora were retractable as found in rumen ophryoscolecids. Raabena bella and Pseudoentodinium elephantis showed high composition values over 30%. Ciliate densities in the three fecal samples were 0.15, 1.09, and 2.07×10(4)/ml.
检测了亚洲象粪便中排出的肠道纤毛虫。共检测到 14 种纤毛目 Entodiniomorphida 目种类。在 Cycloposthiidae 科中发现了 9 种 Triplumaria 种。使用银浸染技术，重新描述了两种已知物种 T. antis 和 T. dvoinosi，并描述了 6 种新物种 T. sukuna n. sp.、T. zuze n. sp.、T. solea n. sp.、T. suwako n. sp.、T. fulgora n. sp. 和 T. harpagonis n. sp.。T. sukuna、T. zuze、T. solea 和 T. suwako 在前庭开口处具有前庭周多纤毛。T. suwako 的颊下纤毛带与从大象中发现的 T. selenica 的纤毛带相似，而 T. sukuna、T. zuze 和 T. solea 的颊下纤毛带与从犀牛中描述的 T. grypoclunis 的纤毛带相似。T. antis、T. dvoinosi、T. fulgora 和 T. harpagonis 的前庭周多纤毛延伸到前庭内部，就像在 Ophryoscolecidae 科的瘤胃纤毛虫中发现的那样。T. dvoinosi 和 T. fulgora 的尾翼纤毛带可缩回，就像在瘤胃 ophryoscolecids 中发现的那样。Raabena bella 和 Pseudoentodinium elephantis 的组成值均超过 30%。在这三个粪便样本中，纤毛虫密度分别为 0.15、1.09 和 2.07×10(4)/ml。
