Remarks on
Scolelepis
(
Scolelepis
)
globosa
Wu & Chen, 1964
Scolelepis
(
Scolelepis
)
globosa
Wu & Chen, 1964
was originally described as
Scolelepis
(
Nerinides
)
globosa
Wu & Chen, 1964
, based on material from the intertidal flat around Zhoushan archipelago in the East
China
Sea. After that, there were no additional reports of the species. According to the original description, the species is characterized by globular expansions at the bases of the palps. It also can be clearly separated from other Chinese
Scolelepis
species by the combination of the characters of the presence of tridentate hooded hooks and occipital tentacle. Therefore, we consider it to be a valid species, but unfortunately neither the
type
materials nor other representative samples are available for examination.
Although the validity of
Scolelepis
(
Scolelepis
)
globosa
Wu & Chen, 1964
is certain, the subgeneric arrangement of the species is confusing.
Wu & Chen (1964)
placed the species in the subgenus
Nerinides
without any detailed explanation. The original description of the species lacks the morphological characters of the neuropodial postsetal lamellae in the posterior part of body, which is the most important taxonomic character for the subgenus
Nerinides
according to
Pettibone (1963)
. Detailed information on the shapes of the neuropodial postsetal lamellae in this species is obviously needed.
The concept of the division of the genus
Scolelepis
into the subgenera
Scolelepis
and
Parascolelepis
has been followed by various subsequent authors (e.g.,
Imajima 1992
;
Blake 1996
;
Delgado-Blas 2006
). The former is characterized by having uni-, bi- or tridentate hooded hooks, while the latter has multidentate hooded hooks. In order to avoid confusion,
Scolelepis
(
Nerinides
)
globosa
Wu & Chen, 1964
should be cited as
Scolelepis
(
Scolelepis
)
globosa
Wu & Chen,
1964
in subsequent studies.
