Antennularia dissimilis Fraser, 1943a

Antennularia dissimilis Fraser, 1943a: 83 , pl. 19, figs. 15a, b.

Nemertesia dissimilis .— Ramil & Vervoort, 2006: 121.

Holotype. MCZ-IZ 9009: USA, Georgia, E of St. Andrew Sound, 30°58’N, 79°34’W, Harvard-Havana Expedition, R/V Atlantis Sta. 3781, 265-290 fm (485–530 m), 24 February 1940, one colony fragment, 4.4 cm high, in poor condition and with nearly all hydrocladia missing, without gonophores, labelled “ type ”; 70% ethanol.

Type locality. USA, Georgia: continental slope, 30°58’N, 79°34’W, 265-290 fm (485–530 m), R/V Atlantis Sta. 3781 ( Fraser 1943a).

Current status. Valid, as Nemertesia dissimilis ( Fraser, 1943a) .

Remarks. No type designation was provided by Fraser (1943a) in his original account of Antennularia dissimilis . Nevertheless, material of the species, labelled “ type ”, exists at the MCZ (MCZ-IZ 9009). Fraser’s description of A. dissimilis was based on a fragment of a single sterile colony. That specimen, the holotype by monotypy, is in poor condition. Few hydrocladia remain, and even then only the most proximal parts are present.

Subsequently referred to Nemertesia Lamouroux, 1812 by Ramil & Vervoort (2006), N. dissimilis is listed as valid in WoRMS. The species, from bathyal waters at the western edge of the Blake Plateau off southern Georgia, is known only from the type locality.
