Host specimens were sampled in the middle course of the River Sanaga (Cameroon) from January to October 2014. Two new species, Protoancylodiscoides auratum n. sp. from Chrysichthys auratus and Protoancylodiscoides combesi n. sp. from C. auratus, Chrysichthys nigrodigitatus and Chrysichthys longidorsalis, are herein described. These new helminths differ from the congeneric species by the size of the haptoral sclerites, the male copulatory organ length, the diameter and morphology of the vagina. At this stage, the present study suggests that Protoancylodiscoides auratum is oioxenous, while P. combesi is stenoxenous. The two new Protoancylodiscoides species bring to three the number of those parasitizing C. auratus, and to four the number of those described from Chrysichthys spp.
2014年1月至10月期间，在喀麦隆萨纳加河中游采集宿主样本。本文描述了两个新物种，即来自金色非洲鲇的金色原锚盘吸虫新种以及来自金色非洲鲇、黑指非洲鲇和长背非洲鲇的孔贝原锚盘吸虫新种。这些新的蠕虫与同属物种的区别在于抱器硬片的大小、雄交配器的长度、阴道的直径和形态。现阶段，本研究表明金色原锚盘吸虫是单宿主性的，而孔贝原锚盘吸虫是狭宿主性的。这两个新的原锚盘吸虫物种使寄生于金色非洲鲇的该属物种数量增至3种，从非洲鲇属鱼类中描述的该属物种数量增至4种。
