Macrostomidae Axia Notes

From Schärer et al. 2011 (citation): "Papi (citation), based on a detailed study of the female antrum, moved Macrostomum gieysztori to the genus Promacrostomum, which is characterized by two female genital openings (citation). Finally, Ferguson (citation) moved the species to the new genus, Axia, to distinguish it from Promacrostomum paradoxum An-der-Lan 1939 (citation), which has a connection between the female antrum and the gut, a feature that is absent in this species. Given that our specimen clusters well within the genus Macrostomum, we suggest that the old name Macrostomum gieysztori be reinstated. Moreover, we note that the genus name Axia has been occupied by a genus of Lepidoptera since 1821 (citation).
