From editor or global species database
Type locality Off the mouth of La Plata River, Argentina, Atlantic Ocean (-48°, -65°). The type locality was stated by Kinberg as being 'off the mouth of La Plata River', but the provided geocoordinates place the site farther southwards, in the vicinity of Cabo Blanco. [details]
Depth range Apparently collected swimming near the surface of the water: "ubi summam aquam fucumque natantem habitat" (Kinberg, 1867: 345).
Distribution South Atlantic Ocean: off Argentina.
Etymology Not stated in the original description. The specific epithet natans is a Latin participle meaning 'swimming' or 'floating',...

Etymology Not stated in the original description. The specific epithet natans is a Latin participle meaning 'swimming' or 'floating', and refers presumably to the habitat where the specimen was found, apparently swimming near the surface of the water: "ubi summam aquam fucumque natantem habitat" (Kinberg, 1867: 345).

Taxonomy Thelepus natans was considered to be a junior synonym of other species in two occasions. First, it was questionably referred to Thelepus comatus (Grube, 1859) by Hessle (1917: 216), who compared the poorly preserved holotype of the first ("Wie gewöhnlich ist doch Kinbergs Originalexemplar allzu schlecht erhalten um eine sichere Identifizierung zu gestatten") with a specimen collected by Dusén in Chile and identified by Hessle as belonging to Thelepus comatus. However, apparently Hessle did not revise the type material of Thelepus comatus. Later, Glasby & Hutchings (1987) revised Dusén's Chilean specimen and referred it to a new species, Thelepus ambitus, while Thelepus natans was referred to Thelepus plagiostoma (Schmarda, 1861) (type locality: New Zealand), with base on the comparison of the type of the first with South African specimens identified as the later. Finally, Hutchings & Smith (1997) redescribed Thelepus plagiostoma with base on topotype material, designated a neotype and relocated the species in its original genus, Terebella. The species was restricted to New Zealand and nearby waters, and while the redescription included Leprea haplochaeta Ehlers, 1904 as a new synonymy, Thelepus natans was not included in the synoynmy list. Thus, apparently the species was removed from synonymy and becomes valid again. [details]
