H. ten Hove, 18 Jun 1983. Diagnosis. Calcareous part of operculum variable in shape, from almost simple plate with two dorsal knobs only to conical or even a diabolo; never with spines. Peduncular wings either with 4–6 digitate processes or simple narrow without such processes (exceptionally with 2 fingerlike processes). Tube one to three longitudinal keels flanked by rows of foramina (pits). Remarks. The occurrence of the temperate/subtropical Atlantic/Mediterranean species Spirobranchus polytrema (Philippi, 1844) in the tropical Indo-West Pacific is rather doubtful (discussions in Imajima (1977: 106) and Pillai (2009: 153)). Likely this material will prove to be genetically different, therefore, we prefer to indicate this taxon with Sp. cf. polytrema. Records of Spirobranchus cf. polytrema from the Indo-West Pacific include two morphotypes, type A and type B (Imajima 1977; also in Fiege & Sun 1999), differing in the distal calcareous opercular cone, peduncular wings with or without digitate processes and expression of longitudinal rows of foramina in the tube. Our material resembles type B in the shape of peduncular wings and tube. However, Straughan’s material (of Temporaria oligotrema) mostly is conform Imajima’s type A, with many foramina (contrary to the name which suggests few; in fact the tube is indistinguishable from that of Spirobranchus minutus Rioja, 1941), as well as Hartmann-Schröder’s (1979) from Western Australia, Pillai’s (1971) material from Sri Lanka and that of Sun & Yang (2001 a) from the South China Sea. Under the Caribbean name Sp. cf. polycerus the latter authors describe a form with intermediate characters between Types A and B. Some of Straughan’s material identified as oligotrema and restudied by one of us (HtH, between 1983 and 2005, unpublished) probably belongs to Sp. corrugatus or even juvenile corniculatus or tetraceros. A complete revision is badly needed but falls out of the scope of this paper. The specific name polytrema is a noun in apposition and need not get the same ending as the generic name (contrary to Pillai 2009), see Article 34.2. 1 of ICZN (1999). Distribution. The nominal species is quite common in the Mediterranean, Atlantic; however, records from the Indo-West Pacific form probably a complex of species by themselves.
