The taxonomic framework of the Haploporidae is evaluated and the relationships within the Haploporinae are assessed for the first time at the generic level using molecular data. Partial 28S and complete ITS2 rDNA sequences from representatives of six of the nine recognised genera within the Haploporinae were analysed together with published sequences. Molecular analyses revealed: (i) a close relationship between the Atractotrematidae and the Haploporidae; (ii) strong support for the monophyly of the Haploporinae, Dicrogaster and Saccocoelium, and the position of Ragaia within the Haploporinae; (iii) evidence for rejection of the synonymy of Saccocoelioides and Lecithobotrys and the validity of the Dicrogasterinae; and (iv) support for the distinct status of Saccocoelium in relation to Haploporus. Forticulcitinae subf. n. was erected for Forticulcita; this resolved Saccocoelioides and, by extension the Chalcinotrematinae, as sister groups to the Haploporinae.

Poprvé byla řešena taxonomie haploporidů uvnitř Haploporinae pomocí molekulárních dat. Poprvé byly analyzovány částečné 28S a úplné ITS2 rDNA sekvence šesti z devíti zástupců platných rodů Haploporinae. Z molekulární analýzy vyplynulo: (i) blízký vztah mezi Atractotrematidae a Haploporidae, (ii) silná podporu monofylie Haploporinae, Dicrogaster a Saccocoelium a postavení Ragaia v rámci Haploporinae, (iii) důkaz pro zamítnutí synonymizace Saccocoelioides a Lecithobotrys a platnost Dicrogasterinae a (iv) podpora pro odlišné postavení Saccocoelium ve vztahu k Haploporus. Forticulcitinae subf. n. byl navržen pro Forticulcita, rozšíření Saccocoelioides a potažmo Chalcinotrematinae, jako sesterské skupiny Haploporinae.
