Summary: | Oswaldella incognita Peña Cantero, Svoboda & Vervoort, 1997 (Figs 8, 16 H, 17H, 19H) Material examined. New Zealand Antarctic Expedition TAN0402: Stn 241 , Tangaroa , 4 March 2004, 66°54'77''– 66°55'01''S, 163°13'65''– 163°13'69''E (off Buckle Island, Balleny Islands), 70– 78 m. Description. Monosiphonic, unbranched stems, up to 130 mm high, divided into internodes. Angle between cauline apophyses and stem ca. 45°. Cauline apophyses with two axillary nematophores, each emerging through simple perisarc hole (Fig. 8 B–C). Hydrocladia bifurcated (Fig. 8 A). First hydrocladial internode with two similar prongs (Fig. 8 A). Mesial inferior nematophore emerging from strongly marked swelling at proximal third of internode (Fig. 8 D–E); with large, claw-shaped nematoteca (Fig. 8 D–F). Hydrotheca elongate, situated on middle or distal half of internode (Fig. 8 D–E). Abcauline wall straight or slightly convex (Fig. 8 D). Hydrothecal aperture circular, roughly perpendicular to long axis of internode (Fig. 8 A, D). Gonothecae fusiform, with subterminal aperture. Published as part of Molinero, A. González & Peña Cantero, A. L., 2015, SEM study of species of Oswaldella Stechow, 1919 (Cnidaria, Hydrozoa, Kirchenpaueriidae), with an annotated checklist of the species of the genus, pp. 401-441 in Zootaxa 4052 (4) on page 412, DOI:10.11646/zootaxa.4052.4.1, http://zenodo.org/record/245887 |
