| Summary: | Sertularella affinicostata , sp. nov. Figs 7a–e, 8 Sertularella costata .— Calder et al ., 2003: 1190, fig. 14a, b [not Sertularella costata Leloup, 1940]. Type locality. Ecuador: Galapagos Islands, Darwin Island, within SCUBA depth, on barnacle cluster (Calder et al . 2003, as Sertularella costata ). Etymology. The specific name is derived from the Latin adjective affinis (akin to) and the name costata , given its resemblance to Sertularella costata . Voucher material. HOLOTYPE: Ecuador: Galapagos Islands, Isla Darwin, SCUBA depth, on barnacle cluster, 26 January 1999, one colony, 1.5 mm high, with gonothecae, coll. K. Collins, ROMIZ B3339. PARATYPES: Ecuador: Galapagos Islands, Cousin Rock, 10 m, on sponge, 17 June 2001, one colony, 5.2 mm high, without gonothecae, coll. D. Calder, ROMIZ B3409.— Ecuador: Galapagos Islands, Marchena Island, Punta Espejo, ca. 8 m, 18 June 2001, four colonies, to 5 mm high, without gonothecae, coll. L.

OTHER MATERIAL: Ecuador: Galapagos Islands, Wolf Island, 6 m, on algae, November 1992, two colonies, to 0.55 mm high, without gonothecae, coll. P. Humann, ROMIZ B3315.— Ecuador: Galapagos Islands, Wolf Island, on stolon of Aglaophenia sp., 25 January 1999, one colony, 1.1 mm high, without gonothecae, coll. J. Mallinson, ROMIZ B3318. Description. Holotype colony unbranched, diminutive, with cauli reaching 1.5 mm high, arising from a hydrorhiza overgrowing cluster of small barnacles. Paratype colonies unbranched to occasionally with a branch or two, with cauli reaching 5.2 mm high, overgrowing a sponge. Basal stolons without internal pegs, diameter 59–83 µm; cauli mostly erect, caulus bearing a maximum of three hydrothecae in holotype, occasionally with a single hydrotheca borne on a short internode in parts of colony, paratypes with as many as 13 cauline hydrothecae (ROMIZ B3418). Hydrocaulus monosiphonic, nearly straight to ... |
