Bimeria tenella Fraser, 1925

? Bimeria tenella Fraser, 1925: 168, figs. 3Α, B.

Garveia tenella .— Cairns et al., 1991: 14.

Type material. CAS-IZ 21 800.00: USA, California, San Francisco Estuary, San Francisco Bay, Southampton Lt. N 10° E, Blunt Point N 65° W, Alcatraz Light S 28° W, 12 August 1912, 22.5 fm (41 m), specimen count 1, coll. USFCS Albatross; 10% formalin.

Type locality. USA, California: San Francisco Bay, several locations near the entrance (close to Southampton Light, Angel Island, and Alcatraz Island), 16–40 m (Fraser 1925).

Current status. Species inquirenda (WoRMS).

Remarks. Type material of Bimeria tenella exists at CAS (CAS-IZ 2 1800.00). Listed there as a syntype, the specimen count is given as “1”. No other type material is known to exist, and the CAS collection may prove to be a holotype by monotypy. The single lot of B. tenella in the Fraser Hydroid Collection at the RBCM (BCPM 976- 00177-001: Cartago Bay) is non-type material. That sample was collected from Isla Isabela, Galápagos Islands, Ecuador, during the 1934 Allan Hancock Pacific Expedition (Fraser 1938a).

Only infertile material of Bimeria tenella was available to Fraser (1925) in describing the species. His hydroid, likely a bougainvilliid, lacked a perisarcal sheath around the bases of the tentacles and is not referable to Bimeria Wright, 1859 . The species was included in Garveia Wright, 1859 by Cairns et al. (1991, 2002). Garveia tenella is listed in WoRMS as a taxon inquirenda.
