Cauline main tube with strong septae. Stem provided with alternate short apophyses giving rise to hydrocladia. Each apophysis with two basal nematothecae (Fig. 7B). Stem with one or two nematothecae between apophyses. Hydrocladia unbranched and alternately arranged in two planes (angle up to 90°). Hydrocladial internodes with strong septae (Fig. 7C–D). Each internode with a hydrotheca and three sessile nematothecae (Fig. 7C–E): one mesial nematotheca adnate to abcauline hydrothecal wall, ... : Published as part of Peña Cantero, Álvaro L. & Horton, Tammy, 2017, Benthic hydroids (Cnidaria, Hydrozoa) from bathyal and abyssal depths of the Northeast Atlantic held in the modern Discovery Collections, pp. 1-30 in Zootaxa 4347 (1) on pages 16-20, DOI: 10.11646/zootaxa.4347.1.1, http://zenodo.org/record/1044772 ... |
