Pol 5322, stn.G 237, Patch Reef near Palfrey Island, 6 m, coll. G. Rouse & E. Kupriyanova, 30 Oct 2005. Diagnosis. Opercular plate mostly flat, sometimes conical; basally carrying 1 medio-ventral spine and 2 laterodorsal spines (“ tricornis ”); alternatively the medio-ventral spine appears as two fully separate spines which with the two latero-dorsal spines leads to 4 primary spines (“ tetraceros ”). All spines are at least split once, generally twice or three times resulting in 6–14 spine tips. Completely conical opercula just with 3 rudimentary spines or without. Peduncular wings with finger-like processes distally (rarely without). Remarks. We have refrained from giving an exhaustive list of synonyms and given some “trusted” Australian records only. This taxon is regarded to be a complex of species in recent years (e.g., Smith 1985: 51–61; Fiege & ten Hove 1999: 362; ten Hove & Kupriyanova 2009: 12, 98; Ben-Eliahu & ten Hove 2011: 91). Its synonymy is very complicated and far from settled. WoRMS (http://www.marinespecies.org/polychaeta/aphia.php?p=taxdetails &id= 131055)—based mainly on ten Hove (1970) as last revision and not fully taking into account Pillai (2009) — lists for this species 33 combinations (including spelling errors) of names, under essentially 8 generic and 17 specific names, as well as 4 more likely synonyms in the remarks. This does not even take into account the frequent misidentifications of Indo-West Pacific material ranging from Pomatoceros triqueter (Linnaeus, 1758) to Spirobranchus giganteus (Pallas, 1776). Ben-Eliahu & ten Hove (2011: 91) give an extensive discussion. The (certainly partly anthropogenic) distribution is very unlikely for a single species in our present view: circumtropical, Lessepsian migrant to the Levantine Mediterranean and in Australia down to subtropical/temperate New South Wales, moreover from intertidal rocks to endobiotic in corals. Indicative of the problems in this taxon is Dew’s (1959: 45–46) record. Following e.g., Fauvel (1933 a: 78–79, Gulf of Suez, Gulf of Aqaba) and Monro (1937: 317, Arabian Sea) she identified her material as Sp. giganteus. However, her figure 17 clearly belonged to Sp. tetraceros as well as her essentially NSW samples, while (part of) her material from Queensland belonged to what we presently would attribute to Sp. corniculatus (material largely restudied by HtH in 1970, 1986). Straughan (1967 a, b, c) attributed three different names to her material, but checking that ten Hove (1970: 47–49) could not find consistent agreement between morphology and attributed names. Distribution. Indo-West Pacific, including Australia (NSW, Qld, WA).
