Material

MALAYSIA: MSL BRY017a, Kuah jetty, Langkawi, fouling mussel shell attached to rope hanging from jetty.

Description

Colony encrusting, multiserial, becoming multilamellar through frontal budding. Basal autozooids ( Fig. 10B View Fig ) subhexagonal, 0.38–0.53 mm long by 0.20–0.28 mm wide; frontally budded autozooids ( Fig. 10C View Fig ) irregularly shaped, about 0.34 mm long by 0.28 mm wide; zooidal boundaries marked by fine fissures; frontal shield gently convex, smooth when first formed, becoming pustulose, peripheral ring of large subcircular areolar pores; orifice generally inclined distally, about 0.15 mm long by 0.13 mm wide, with a distinct rounded sinus ( Fig. 10D View Fig ), a pair of condyles present in proximal part of anter; two short, widely separated oral spines with closed ends can occur ( Fig. 10D View Fig ); ovicell hood-like ( Fig. 10E View Fig ), broad, about 0.10 mm long by 0.20 mm wide, surface with pustules, non-porous.Adventitious avicularia located suborally ( Fig. 10 View Fig D–E), slightly eccentric to median axis, frontal plane almost perpendicular to surface of autozooid, small; rostrum rounded, tip dentate; cross-bar calcified. Interzooidal avicularia ( Fig. 10F View Fig ) distributed irregularly among frontally budded autozooids, variable in size, up to 0.32 mm long by 0.15 mm wide, distal end slightly raised; rostrum spatulate, rounded, distally dentate; cross-bar calcified, some with small lingulum; opesia semielliptical, wider than long.

Remarks

Malaysian specimens of Celleporaria aperta clearly show the dentate distal tips of the avicularian rostra ( Fig. 10F View Fig ), like those depicted by Hincks (1882: pl. 5, fig. 3), but not apparent in all material attributed to the species by subsequent authors. Hincks (1882: 126) gave the provenance of his material as “ Singapore or Philippines ” and the species is regarded as widespread in the tropical and subtropical Indo-Pacific ( Gordon et al. 2007).
