| Summary: | Acryptolaria minuta Watson, 2003 (Figs 1D, 3 E–F, 5G) Acryptolaria minuta Watson, 2003: 163–164, fig. 13A–C; Peña Cantero et al., 2007: 256–258, figs 11, 16C; Peña Cantero & Vervoort, 2010: 302–304, figs 18, 30. Material examined. Eltanin : 27/1852, several fragments and stems up to 15 mm high, on bryozoans (mounted on two microslides). Description. Branches and stems roughly straight. Hydrothecae alternate in two planes making a very obtuse angle. Hydrotheca tubular, free part cylindrical; diameter slightly decreasing basally at adnate part. Hydrotheca curved outwards; sometimes quite strongly. Hydrotheca adnate to internode for around two thirds of its adcauline length. Adcauline wall convex; much more at free part. Abcauline wall concave at distal half; practically straight at basal half. Hydrothecal aperture circular, directed up- and outwards, sometimes almost parallel to long axis of branch. Rim even, without renovations. Measurements (in µm). Hydrothecae: abcauline wall 690–810, free part of ... : Published as part of Peña Cantero, Álvaro L., 2020, Species of Acryptolaria Norman, 1875 (Cnidaria: Hydrozoa) collected by US Antarctic and sub-Antarctic expeditions, pp. 277-294 in Zootaxa 4767 (2) on page 288, DOI: 10.11646/zootaxa.4767.2.4, http://zenodo.org/record/3771174 ... |
