BCPM 976-00818-002: Japan, Sagami Bay, Arasaki, 70-80 m, 0 4 August 1931, one part of a colony, 1.7 cmhigh, in excellent condition, with gonothecae; slide.

Typelocality. Japan: Sagami Bay, near Hayama, 70-80 m( Fraser 1935b). Current status.Valid, but see Remarks below.
Remarks.These hydroids, sent to Fraser (1935b)for identification from the collection of Emperor Hirohito, are from Sagami Bay, Japan. Although only one of the samples listed above at the RBCM is marked “ type” (BCPM 976-00818-001), both are taken here to represent syntypematerial (see ICZN Art. 72.4.7) and are likely from the same collection. No name-bearing typewas designated by Fraser in the original account of the species, and none has subsequently been made to our knowledge. While Fraser labelled a fluid specimen (BCPM 976-00818-001) as the “ type”, it comprises fragments of one or more colonies, and is included here as a paralectotype. A single colony fragment apparently from the same sample on a microscope slide (BCPM 976-00818-002), in excellent condition and with gonothecae, is designated here as the lectotype. Severaldozen records of Antennella paucinoda, from Sagami Bay, Japan, also exist in the Emperor Shōwa Hydroid Collectionat the NMNS. Threeof them are from the same locality as those at the RBCM(NSMT-HyR 147, NSMT-HyR 148, NSMT-HyR 149). Hirohito (1995)noted the resemblance of A. paucinodato several other species of AntennellaAllman, 1877, but treated it as distinct. The validity of the species has been questioned in several subsequent works. Authors including Schuchert (1997)and Vervoort & Watson (2003)included it in the synonymy of A. secundaria( Gmelin, 1791). In more recent accounts ( Schuchert 2015; WoRMS), A. paucinodais listed as a synonym of A. quadriaurita Ritchie, 1909, a species it more closely resembles in having two lateral nematothecae of unequal size on either side of each hydrotheca. Given the present irresolution of its relationships, together with its Japanese typelocality and the remote South Atlantic typelocality of A. quadriaurita(Gough Island), we follow Hirohito in recognizing it as valid. The species is common in Sagami Bay ( Hirohito 1995).
