Terebellidae (Polychaeta: Terebellida) from the Grand Caribbean region 2320 Author Londoño-Mesa, Mario H. text Zootaxa 2009 2009-12-22 2320 1 1 93 https://biotaxa.org/Zootaxa/article/view/zootaxa.2320.1.1 journal article 10.11646/zootaxa.2320.1.1 1175­5334 5316176 Eupolymnia Verrill, 1900 Verrill, 1900:660 (syn.).— Hessle, 1917:174 , Text-Fig. 41 (as Polymnia ).— Hartmann-Schröder, 1996:509 .— Capa & Hutchings, 2006:4 . Synonyms: Amphitritoides Costa, 1862 nomen oblitum ; Pallonia Costa, 1862 nomen oblitum ; Polymnia Malmgren, 1867 (preoccupied by a bird genus). Type species : Amphitrite nesidensis delle Chiaje, 1828 , by subsequent designation. Diagnosis: Branchiae on segments 2–4; eyespots sometimes present; lateral lappets on segments 2–3 or 2–4; ventral shields from segment 2; nephridial papillae from segment 2 or 3, continuous or discontinuous, along 3–9 segments; 17 pairs of notopodia from segment 4, notochaeta smooth, bilimbate; neuropodia from segment 5, uncini avicular in single rows on segments 5–9 or 10; in double rows, arranged face to face, until segment 20; thereafter in single rows. Remarks : The name Eupolymnia Verrill, 1900 , is considered nomen protectum and the names Amphitritoides Costa, 1862 and Pallonia Costa, 1862 are considered nomen oblitum , according to the ICZN (1999) , articles 23.9.1 and 23.9.2. Holthe (1986b) recognized 18 species, but a recent study of species and diagnostic characters by Capa and Hutchings (2006) reported 20 species, of which only E. crassicornis ( Schmarda, 1861 ) , from Bermuda , has been described from the Grand Caribbean region. Terebella turgidula Ehlers, 1887 , from Florida, has been synonymized with E. crassicornis , ( Augener, 1925 ; Hartman, 1938 ; Rullier, 1974 ; Holthe, 1986b ). Nevertheless, the number of pairs of notopodia and the shape of chaeta and uncini are different in both species, which suggests T. turgidula does not belong to Eupolymnia . On the other hand, Treadwell (1924) mentioned that Terebella magnifica Webster, 1884 , from Bermuda , belongs to Eupolymnia as defined by Verrill (1900) . Hence, E. magnifica ( Webster, 1884 ) is listed by Perkins and Savage (1975) and by Salazar- Vallejo (1996) for the Grand Caribbean region, according to previous reports. Type material of E. magnifica has been compared with non-type material of E. nebulosa ( Montagu, 1818 ) but from the type locality ( England ), and it was found that both species differ mainly in the shape of uncini along the body. Thus, a revision of the genus is needed to clarify the distribution of some species and the relationships between them. E. rullieri sp. nov. , is described from Mexican Caribbean . Consequently, the genus is represented in the region by three species described.
