Kankana manampoka n. gen., n. sp. (Monogenea, Polystomatidae), is described from the urinary bladder of the narrow-mouthed frog Platypelis pollicaris. This is the first record of a polystome from the Microhylidae and the third polystome genus from Madagascar, next to Metapolystoma and Madapolystoma. The extensive uterus and presence of hamuli resemble Metapolystoma but the vitellarium confined to the lateral fields in Kankana is different. Madapolystoma also has an extensive uterus but contain only up to 32 advanced developed larvae. Based on the extensive uterus filling the body proper and the vitellarium confined to two lateral fields posterior in the body this new polystome resembles Eupolystoma known from Africa and India. However, unlike Eupolystoma, the gonads are in the middle of the body, vaginae are lacking and a pair of hamuli is present. A molecular phylogenetic analysis of concatenated 18S and 28S ribosomal RNA gene sequences supplemented by genetic distances inferred from 28S and COI sequences showed that this new genus is more related to Madapolystoma, a genus only reported from Madagascar, than to Eupolystoma known from Africa and India and Metapolystoma known from Africa and Madagascar.
卡坎纳蛙吸虫新属新种（复殖吸虫纲，多口科），是在窄口蛙 Platypelis pollicaris 的膀胱中发现的。这是来自姬蛙科的多口吸虫的首次记录，也是马达加斯加的第三个多口吸虫属，仅次于后多口吸虫属和马达加斯加多口吸虫属。其广泛分布的子宫和小钩的存在类似于后多口吸虫属，但卡坎纳蛙吸虫的卵黄腺局限于身体两侧区域，这一点有所不同。马达加斯加多口吸虫属也有广泛分布的子宫，但最多仅含有32个发育成熟的幼虫。基于充满整个身体的广泛分布的子宫以及局限于身体后部两侧区域的卵黄腺，这种新的多口吸虫类似于已知来自非洲和印度的真多口吸虫属。然而，与真多口吸虫属不同的是，其生殖腺位于身体中部，没有阴道，且有一对小钩。对串联的18S和28S核糖体RNA基因序列进行的分子系统发育分析，并辅以从28S和细胞色素氧化酶亚基I（COI）序列推断出的遗传距离，结果表明，这个新属与仅在马达加斯加有报道的马达加斯加多口吸虫属的关系，比与已知来自非洲和印度的真多口吸虫属以及已知来自非洲和马达加斯加的后多口吸虫属的关系更为密切。
