Halicornaria sinuosa Fraser, 1925: 171, figs. 7Α–C. Gymnangium sinuosum.— Vervoort, 1968: 114.
Syntypes.CAS-IZ 0 21 804.00: USA, Florida, USS Fish HawkSta. 7511, Gulf Stream off Cape Florida, 2 1/ 8 miles( 3.4 km) SSE of Fowey Rocks Lighthouse, 45 fm ( 82 m), 25 May 1903, labelled “ syntype”; 10% formalin. BCPM 976-00861-001: USA, Florida, Gulf Stream off Cape Florida, 45 fm ( 82 m), several colony fragments, up to 5.9 cmhigh, in fair condition, without gonophores, labelled "co-type”; 60% IPA. BCPM 976-00861-002: USA, Florida, Gulf Stream off Cape Florida, 45 fm ( 82 m), one colony fragment, 1.5 cmhigh, in good condition, without gonophores; slide. Lectotype, by present designation.BCPM 976-00861-002: USA, Florida, Gulf Stream off Cape Florida, 45 fm ( 82 m), one colony fragment, 1.5 cmhigh, in good condition, without gonophores; slide. Paralectotypes.CAS-IZ 0 21804.00: USA, Florida, USS Fish hawkSta. 7511, Gulf Stream off Cape Florida, 2 1/ 8 miles( 3.4 km) SSE of “Fovey Rock Light” (=Fowey Rocks Light), 45 fm ( 82 m), 25 May 1903, numerous colony fragments, in poor condition, with Aglaophenia rigida(= A. trifidaAgassiz, 1862), labelled “ syntype”; 10% formalin. BCPM 976-00861-001: USA, Florida, Gulf Stream off Cape Florida, 45 fm ( 82 m), several colony fragments, up to 5.9 cmhigh, in fair condition, without gonophores, labelled "co-type”; 60% IPA.
Typelocality. USA, Florida: Gulf Stream off Cape Florida, 2 1/ 8 miles( 3.4 km) SSE of Fowey Rock Light, 45 fm ( 82 m) ( Fraser 1925). Current status.Valid, as Gymnangium sinuosum( Fraser, 1925).
Remarks.In describing Halicornaria sinuosa, no name-bearing typewas fixed by Fraser (1925). However, syntypematerial of Halicornaria sinuosawas located at both the CAS (CAS-IZ 0 21804.00) and the RBCM (BCPM 976-00861-001, BCPM 976-00861-002). The material at CAS is fragmentary and in poor condition. We therefore designate the best available syntypematerial as the lectotype(BCPM 976-00861-002). The species, now assigned to genus Gymnangium Hincks 1874as G. sinuosum, is regarded as valid ( Cairns et al. 2002; Calder & Cairns 2009; WoRMS). The synonymy of this species has been listed elsewhere, along with redescriptions, additional illustrations, and taxonomic remarks ( Bogle 1975; Calder 1997; Ansín Agís et al. 2001).
