There are two similar but clearly distinct and easily distinguishable Diphasia species in the NE Atlantic
Diphasia alata Hincks (1855) and
Diphasia margareta (Hassal, 1841).

The situation of Diphasia pinastrum (Cuvier, 1830) [= S. pinaster Ellis & Solander, 1786] is debatable.
Although Ellis & Solander (1786) depict hydrothecae with a sharp kink - typical for D. alata - two other details strongly argue in favour that Ellis and Solander had rather Diphasia margareta and not D. alata:
- the gonothecae are much too big for D. alata: the latter species as very small gonothecae (max 0.7 mm), not much larger than the hydrotheca. This is well illustrated in Hincks (1868: pl 48 fig. 2a) and has been checked for several other samples. The gonothecae of D. margareta are 2- 4 mm in length (comp. data in Cornelius 1979)
- the spacing of the hydrothecal pairs is too wide for D. alata: the latter species has a very tight spacing of the hydrothecal pairs, while they are much wider spaced in D. margareta.

Cornelius (1995b: 35) has concluded otherwise, but he was perhaps mislead by the schematic drawings of the hydrothecae in Ellis & Solander (1786).
For the sake of nomenclatural stability, it is thus best to continue the use as given in Cornelius (1995b) and use the names Diphasia alata Hincks (1855) and Diphasia margareta (Hassal, 1841), while Sertularia pinaster Ellis & Solander, 1786 should be regarded as a questionable synonym of Diphasia margareta.
