Zusammenfassung:A detailed comparative anatomy of the monotypic genus Wuconchona Kang from Hubei Province, China is presented. The data are used for a phylogenetic analysis involving the ten known genera of Triculinae: Triculini sensu Davis 1979. A new tribe, Pachydrobiini is named in which Wuconchona is classified, thus dividing the Triculini sensu Davis 1979 into the Triculini (Tricula, Delavaya, Fenouilia, Lacunopsis) and the Pachydrobiini (Halewisia, Neotricula, Pachydrobia, Robertsiella, Jinghongia, Wuconchona). Jinghongia Davis gen. nov. is described for a species previously classified as Neotricula. An important aspect of the evolution in this clade is the parallel loss in several lineages of the normal seminal receptacle and the replacement of the seminal receptacle with derived structures. The solution in the Triculini is different from those in the Pachydrobiini. The known capability of each clade to transmit a species of Schistosoma is presented.
