The present paper includes a morphological, ecological and biological updating of the three gorgonian associated species
of
Haplosyllis
(Polychaeta, Syllidae) known to date:
H. chamaeleon
(symbiont with
Paramuricea clavata
in the
Mediterranean),
H. anthogorgicola
(symbiont with
Anthogorgia bocki
in the Japanese seas) and
H. villogorgicola
,
a new species living symbiotically with
Villogorgia bebrycoides
which is only known from Tenerife (Canary Islands,
Eastern Central Atlantic). The new species is described on the basis of ecological, morphological, morphometric and
statistical analysis of relevant characteristics. Each host colony harboured about 15 pale-yellowish worms, whose
cryptic colouration mimicked that of the host. They occurred either on the host branches or partly hidden inside cavities
formed by the fusion of two branches. The new species is characterized by the presence of simple chaetae with
clearly bidentate tips all along the body, the presence of gland pore aggregates distributed in two lateral rows and
two ventral patches on each palp and the absence of ciliary tufts on the pharyngeal papillae.
H. villogorgicola
sp.
nov.
is closely related to
H. chamaeleon
. Thus, it is compared with two populations of this species collected in the
north-west and south-west Mediterranean. Stolons of
H. chamaeleon
are re-described as tetracerous and a peculiar
posterior end regeneration process occurring in adult worms during the stolon formation is described.
H. anthogorgicola
is also re-described, with particular emphasis on its appendage and chaetal arrangements. The
main features of the three associations are discussed in light of the current knowledge on symbiotic polychaetes, particularly
cnidarian-associated syllids. © 2002 The Linnean Society of London,
