Anuran filarial nematodes are restricted to two comparatively small subfamilies (Icosiellinae and Waltonellinae) of the filariae that currently comprise six genera and 41 recognised species. However, the life histories of only five anuran filarial nematodes, proposed as an ancestral group based on molecular phylogenetic studies, have been elucidated. Furthermore, data on the natural vectors (in situ) and parasite transmission is limited. In the current study we elucidate the life history of Neofoleyellides boerewors n. gen. n. sp. parasitising the guttural toad, Sclerophrys gutturalis and the mosquito vectors Uranotaenia (Pseudoficalbia) mashonaensis and Uranotaenia (Pseudoficalbia) montana. Additionally, we report on the unique host-seeking behaviour of the mosquito vectors which locate their toad hosts using their calls. The complex host-vector relationship and specialised host-seeking behaviour by these mosquitoes indicate biases towards host species and male toad infections.
无尾目丝虫仅局限于丝虫目两个相对较小的亚科（Icosiellinae 和 Waltonellinae），目前包括 6 个属和 41 个已确认的种。然而，只有五种无尾目丝虫的生活史得到了阐明，这些丝虫被提出作为基于分子系统发育研究的一个祖群。此外，关于自然传播媒介（原位）和寄生虫传播的数据是有限的。在本研究中，我们阐明了寄生在喉蛙（Sclerophrys gutturalis）身上的 Neofoleyellides boerewors n. gen. n. sp. 的生活史，以及蚊子传播媒介 Uranotaenia (Pseudoficalbia) mashonaensis 和 Uranotaenia (Pseudoficalbia) montana。此外，我们还报告了蚊子独特的宿主寻找行为，这些蚊子利用它们的叫声来定位它们的蛙类宿主。这些蚊子与宿主之间复杂的关系和特殊的宿主寻找行为表明，它们偏向于宿主物种和雄性蛙类感染。
