Summary: | Symplectanea bracteata Fraser, 1941b Symplectanea bracteata Fraser, 1941b: 78, pl. 13, figs. 1a, b. Monocoryne bracteata .— Rees, 1957b: 19, unnumbered figures. Syntypes. USNM 43450: USA, Alaska, Alexander Archipelago, Admiralty Island, Stephens Passage, Thistle Ledge, R / V Albatross Sta. 4253, 14 July 1903, Tanner beam trawl, 240–344 m, fragments of two polyps, labelled “ type ”; ethanol. Lectotype, by present designation. USNM 43450: USA, Alaska, Alexander Archipelago, Admiralty Island, Stephens Passage, Thistle Ledge, R / V Albatross Sta. 4253, 14 July 1903, Tanner beam trawl, 240–344 m, three fragments of one polyp, in fair condition, with gonophores, labelled “ type ”; ethanol. Paralectotype. USNM 1458906: USA, Alaska, Alexander Archipelago, Admiralty Island, Stephens Passage, Thistle Ledge, R / V Albatross Sta. 4253, 14 July 1903, Tanner beam trawl, 240–344 m, fragments of one polyp, in poor condition, with gonophores; ethanol. Type locality. USA, Alaska: Stephens Passage, Thistle Ledge, 131 fm (240 m) (Fraser 1941b). Current status. Valid, as Monocoryne bracteata (Fraser, 1941b). Remarks. Fraser’s (1941b) “ type ” of Symplectanea bracteata (USNM 43450) is currently recorded in the online NMNH database as syntype material with a specimen count of “1”. No other types of the species are known to exist. Fraser (1941b) clearly examined more than one polyp because his description of the species begins with the words “Solitary zooids grow from a broad base…” According to Rees (1957b), who examined the sample from the NMNH, “torn fragments of two solitary capitate hydroids” were present. Although the same material has been referred to as the holotype by both Stepanjants et al . (2003) and Brinckmann-Voss & Lindner (2008), these two polyps are indeed syntypes. Our examination revealed that both specimens are fragmented. Three parts of the larger polyp were matched and constitute what we designate here as the lectotype (USNM 43450). This polyp corresponds with the specimen illustrated in Fraser’s original ... |
