Remarks

There is some doubt regarding the correct date for the citation of this species. Past reviewers (Vosseler 1901; Shih 1969, 1971) have cited Guérin­Méneville, 1836a, and, although this is the correct date for the plates, the text was not completed until the end of 1843 (see remarks on P. atlantica). Phronima solitaria was not figured in any of the plates, and was only described on p. 21 of the text, which was not published until 1844! This should therefore be the date used when citing this species (e.g. Spamer & Bogan 1992, 1994). Incidentally, the reference given by Shih (1969) for the original description of this species refers to P. atlantica .

Phronima solitaria was considered a mere variety of P. atlantica by Vosseler (1901) but Shih (1969) elevated it again to specific status, a decision which is supported by the examination of the type.

The similarity of this species to P. sedentaria has already been discussed under that species.
