Notes for Macrostomidae Macrostoma
Von Graff (1905) states on page 109 that according to Agassiz the genus Macrostoma was already given to a fish genus by Risso 1826.Notes for Macrostomidae Axia
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).Notes for Macrostomidae Inframacrostomum
The erection of the genus Inframacrostomum by Ferguson (1954) (citation), was immediately rejected by Papi (1959) (citation) and Ax (1959) (citation), and further supported by Schmidt & Sopott-Ehlers (1976) (citation), Faubel et al. (1994) (citation), Schärer et al. (2011) (citation), and Schockaert (citation). Since the name has still sometimes appeared, it was again clarified by Brand et al. (2022) (citation) that Inframacrostomum is a synonym of Macrostomum.Notes for Macrostomidae Archimacrostomum
The erection of the genus Archimacrostomum by Ferguson (1954) (citation), was immediately rejected by Papi (1959) (citation) and Ax (1959) (citation), and this rejection was further supported by Schmidt & Sopott-Ehlers (1976) (citation), Schärer et al. (2011) (citation), and Schockaert (citation). Since the name has still sometimes appeared, it was again clarified by Brand et al. (2022) (citation) that Archimacrostomum is a synonym of Macrostomum.Notes for Macrostomidae Promacrostomum
Based on phylogenomic analyses Brand et al. 2022 (citation) show i) that the type species of Promacrostomum falls into Macrostomum, and ii) that the presence of a second female genital opening has evolved multiple times in Macrostomum. Based on this Promacrostomum is a synonym of Macrostomum.Return to Macrostomidae Promacrostomum
