;
Polymnia

Type
species
:
Amphitrite nesidensis
delle
Chiaje, 1828
, by subsequent designation.
Diagnosis:
Branchiae on segments 2–4; eyespots sometimes present; lateral lappets on segments 2–3 or 2–4; ventral shields from segment 2; nephridial papillae from segment 2 or 3, continuous or discontinuous, along 3–9 segments; 17 pairs of notopodia from segment 4, notochaeta smooth, bilimbate; neuropodia from segment 5, uncini avicular in single rows on segments 5–9 or 10; in double rows, arranged face to face, until segment 20; thereafter in single rows.
Remarks
: The name
Eupolymnia
Verrill, 1900
, is considered
nomen protectum
and the names
Amphitritoides
Costa, 1862
and
Pallonia
Costa, 1862
are considered
nomen oblitum
, according to the
ICZN (1999)
, articles 23.9.1 and 23.9.2.
Holthe (1986b)
recognized 18 species, but a recent study of species and diagnostic characters by
Capa and Hutchings (2006)
reported 20 species, of which only
E. crassicornis
(
Schmarda, 1861
)
, from
Bermuda
, has been described from the Grand
Caribbean
region.
Terebella turgidula
Ehlers, 1887
, from Florida, has been synonymized with
E. crassicornis
, (
Augener, 1925
;
Hartman, 1938
;
Rullier, 1974
;
Holthe, 1986b
). Nevertheless, the number of pairs of notopodia and the shape of chaeta and uncini are different in both species, which suggests
T. turgidula
does not belong to
Eupolymnia
. On the other hand,
Treadwell (1924)
mentioned that
Terebella magnifica
Webster, 1884
, from
Bermuda
, belongs to
Eupolymnia
as defined by
Verrill (1900)
. Hence,
E. magnifica
(
Webster, 1884
)
is listed by
Perkins and Savage (1975)
and by Salazar- Vallejo (1996) for the Grand
Caribbean
region, according to previous reports.
Type
material of
E. magnifica
has been compared with non-type material of
E. nebulosa
(
Montagu, 1818
)
but from the
type
locality (
England
), and it was found that both species differ mainly in the shape of uncini along the body. Thus, a revision of the genus is needed to clarify the distribution of some species and the relationships between them.
E. rullieri
sp. nov.
, is described from Mexican
Caribbean
. Consequently, the genus is represented in the region by three species described.
