Material examined. – 1 colony (1999.1043), Pulau Semakau , coll. S.L.M. Teo & T. H. Choong, 12 Jun.1995 ; 1 colony (1999.1054), Pulau Hantu , south-east side of Is., reef flat, coll. S.L.M. Teo & C.S.C. Lee, 8 Mar.1993 ; 1 colony ( ZRC 1999.1080 View Materials ), Pulau Hantu , south-east side of Is., coll. S.L.M. Teo, 16 Feb.1995 ; 1 colony ( ZMTAU Co 35104) [ ZRC 1999.2224 View Materials ], Pulau Hantu, 1–4 m, coll. Y. Benayahu, 15 Jul.1999 ; 1 colony ( ZRC 1999.2229 View Materials ), Pulau Hantu , 1–4 m, coll. Y. Benayahu, 9 Jul.1999 ; 1 colony (1999.2268), Pulau Satumu (Raffles Lighthouse), 3–6 m, coll. Y. Benayau, 15 Jul.1999 .

Remarks. – The discussed colonies from Singapore resemble

the holotype of S. acuta , except for ZRC 1999.2268, which shows certain differences. For comparison, both the colony and sclerites of ZRC 1999.2268 are presented here ( Figs. 1b View Fig , 5–7 View Fig View Fig View Fig ). The colony shape ( Fig. 1b View Fig ) corresponds to the description of the holotype (Manuputty & Ofwegen, 2007: Fig. 2a View Fig ). The sclerites of the polypary fit those of the holotype, including the polyp point ( Fig. 5a View Fig ) and crown ( Fig. 5b View Fig ), the clubs of the surface layer of the lobes ( Fig. 5c, d View Fig ) and its spindles ( Fig. 5e View Fig ) (see Manuputty & Ofwegen, 2007: Fig. 3 View Fig ). Similarly, the sclerites of the surface layer of the base, including the clubs ( Fig. 6a, b View Fig ) and spindles ( Fig. 6c View Fig ), correspond to the holotype (Manuputty & Ofwegen, 2007: Fig. 4 View Fig ). However, the spindles of the interior of the lobules of ZRC 1999.2268 are mostly branched ( Fig. 7a View Fig ), as opposed to those of the other examined colonies (see above) and the holotype (Manuputty & Ofwegen, 2007: Fig. 4c View Fig ). The tubercular ornamentation of the spindles of all the colonies corresponds to the holotype ( Fig. 7b, c, e, f View Fig ). Notably, even the spindles in the interior of the base of ZRC 1999.2268 occasionally feature a side branch ( Fig. 7d View Fig ). We consider the slender spindles of the holotype of S. acuta , which are up to 3.6 mm long, a diagnostic of the species. The spindles depicted in Fig. 7a View Fig , are indeed of this type, up to 4 mm long, yet branched. Such differences between the holotype of S. acuta and the discussed colony are considered to reflect intra-specific variation, as commonly found in other Sinularia species (e.g., Dautova et al., 2010).
