Eudendrium cf. scotti Puce, Cerrano & Bavestrello, 2002 View in CoL

(fig. 7E–G)

Eudendrium scotti Puce, Cerrano & Bavestrello, 2002: 370 View in CoL , figs 4–5.

Material examined. Stn. CFA — 14.iii.2006, 10– 30 m, S88: a small, sterile colony, epizoic on Sertularella polyzonias ( MHNG INVE 53320 ) . Stn. PAB — 10.iii. 2006, 20 m, S85a: several hydranths, without gonophores, epizoic on Symplectoscyphus subdichotomus ( MHNG INVE 53299 ) . Stn. CPA — 09.iii. 2005, 15 m, S170: a small, sterile colony, epizoic on Symplectoscyphus subdichotomus ( MHNG INVE 53501 ) .

Type locality. Tethys Bay (Terra Nova Bay), Antarctica .

Description. Colonies generally small (less than 1 cm high), delicate, composed of single pedicellate hydranths or erect and few branched stems, arising from a creeping stolon. Perisarc thin and transparent or slightly brown basally, annulated at base of side branches (2–7 annuli), smooth elsewhere. Hydranths urnshaped, with 14–20 filiform tentacles. Gonophores not seen. Cnidome:

a) small microbasic euryteles on tentacles, undischarged (6.9–7.2) x (3.3–3.6) µm, discharged (6.9–7.2) x (3.6–3.9) µm;

b) large macrobasic euryteles on hydranth body, hypostome, fewer in the coenosarc, undischarged (21.0– 22.3) x (10.2–10.8) µm.

Remarks. The identification of this hydroid is somewhat uncertain because gonophores are lacking. Neverthless, the present material agrees well with the description and illustrations of E. scotti by Puce et al. (2002) from Antarctica, who also described the gonophores of this species.

World distribution. Reported only from the Antarctic ( Puce et al., 2002).

Records from Chile. The present records are situated roughly between 48°50' S and 50°30' S. This is the first records of the species for Chile .
