One specimen (
ECOSUR
), slightly bent ventrally, collected during night dive,
26 Aug. 2019
, J. Xie, coll. (body grayish, dorsal pigmentation includes a blackish middorsal 8-shaped band, anterior region wider than posterior one, waist very thin, surrounded by two curved bands (parenthesis-like), and lateral bands running from the posterior third along anterior parapodial surfaces, and a shorter interramal blackish spot; dorsal cirri blackish; branchiae grayish, with stems black along their lower half; caruncle with median ridge blackish;
70 mm
long,
11 mm
wide, 33 chaetigers).
Diagnosis
.
Chloeia
with bipinnate branchiae from chaetiger 4, progressively smaller posteriorly; middorsal spots band-shaped, constricted medially, separated into two spots in median segments; prenotopodial dark band narrow; harpoon notochaetae without spurs; neurochaetae spurred and furcates.
Remarks
.
Chloeia bimaculata
Wang, Zhang, Xie & Qiu, 2019
resembles
C. amphora
Horst, 1910
described from
Indonesia
, because it has dorsal spots varying from an amphora like spot along chaetigers 3–7, although in following segments spots have a median constriction or waist, becoming thinner along median and posterior chaetigers, and in some only two larger spots remain, hence the specific name.
Wang
et al.
(2019)
made no comparison with any other species, but these two species differ in the
type
of spots, and also in some chaetal features. Thus, in
C. bimaculata
anterior notochaetae are spurred, pale, and harpoon notochaetae are smooth, or have a tiny spur, whereas in
C. amphora
anterior notochaetae are furcates with golden tines, and most harpoon notochaetae have a well-developed spur.
Distribution
. Only known from
Hong Kong
shallow water sediments.
