Stem resting on short apophysis. First two cauline internodes with two nematothecae, third internode longer and provided with six nematothecae (Fig. 9A). Remaining stem divided by alternating oblique and transverse nodes into an alternate series of hydrothecate/ahydrothecate internodes (Fig. 9B–D). Ahydrothecate internodes typically with three medial nematothecae (Fig. 9C), although internodes with only one also present (Fig. 9B). Hydrothecate internodes with one hydrotheca and four nematothecae: two flanking hydrothecal aperture on long pedicels (Fig. 9E) (frequently one without pedicel), one nematotheca at axil between adcauline hydrothecal wall and internode (Fig. 9D) and a mesial infrathecal nematotheca not ... : 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 20-23, DOI: 10.11646/zootaxa.4347.1.1, http://zenodo.org/record/1044772 ...
