Remarks In material MNHN-IK-2015-426, the perisarc of the colony may be wavy to wrinkled in places, and the corrugations of the hydrothecae are more conspicuous, encompassing also their abaxial wall. The hydrothecae in sample MNHN-IK-2015-419 display seven internal projections of the perisarc: four latero-adaxial, of which the two adaxial-most are the most prominent, one large abaxial, and two smaller latero-abaxial (Fig. 14D). Its gonothecae are believed to be male, owing their shape and size (ca 1680 µm long and 505 µm wide, only one measured), compared to those from the holotype (see Galea 2016); they are given off laterally from the middle of the internode on side opposite to hydrotheca but, soon after, they are shifted on to the anterior/posterior side of the colony; club-shaped, with slightly undulated walls, aperture distal, rounded, small (ca 100 µm wide), borne on rather short and narrow neck region.

Schories, lot #05; 25.04.2007; colony composed of several profusely-branched, polysiphonic stems, up to 10 cm high, some bearing male gonothecae (holotype). – HRG-1178; Chile, Región de Aysén, Isla Waller, -46.7648° -75.2312°, 20 m, coll. HSFS, HF24, lot #128; 20.04.2015; three colonies with polysiphonic stems, 4.5, 5.8, and 7.0 cm high, the latter bearing a male gonotheca. Description: Colonies erect, up to 10 cm high, arising from creeping, branching stolon. Stems either mono- or polysiphonic. Basal part of monosiphonic stems of varied length, not constricted above origin from stolon, ahydrothecate, with smooth perisarc; remainder of stem composed of a succession of moderatelylong, slightly geniculate internodes delimited by rather indistinct, oblique nodes sloping in alternate directions. A hydrotheca, or a hydrotheca and a short, lateral apophysis immediately below its base, confined to the distal end of each internode. Branching pattern alternate and coplanar, with generally 3 hydrothecae between successive side branches, but possibly 1 to 9; up to 3rd order branching observed; branches with similar structure as the stem, though 1 st internode comparatively longer than subsequent ones. Hydrothecae tubular, distinctly curved outwards, adnate for about half their length to the corresponding internode; abaxial wall straight for 3/4th its length, conspicuously curved outwards below rim; free adaxial wall slightly convex, perisarc smooth to wavy, in the latter case provided with 2-3 indistinct undulations, more conspicuous proximally; hydrothecal aperture expanding just below rim; the latter provided with 4 acute cusps separated by moderately-deep, semi-circular embayments; operculum composed of 4 triangular flaps, with concentric, closely-set striae. Gonothecae arising from below the hydrothecal bases; male and female similar, though of slightly different size; broadly ovoid, with 6-7 transverse ribs, the 3-4 distalmost well-marked, becoming obsolete towards base; aperture mounted on short, terminal collar, truncate distally and provided with 4 blunt perisarc projections; female with acrocysts. Dimensions: See Table 7.

Main tube of the stem undivided, but equivalents of internodes with a lateral apophysis and a number of nematothecae above; apophyses alternate, coplanar, each with a mamelon, continued directly into a main hydrocladium; two accessory cladia, projecting outward and slightly upward, are given off laterally from below both sides of the mamelon; main hydrocladium divided into internodes with hydro- and nematothecae; accessory cladia shorter and thinner than main counterpart, generally composed of nematothecae-bearing internodes, occasionally with 1–2 intervening hydrothecate internodes distally. Hydrothecae cup-shaped, without associated nematothecae. Gonothecae unknown.</p> Etymology <p> From Ancient Greek ‘ <i>ἀΚτίς</i> ’, meaning ‘ray’, and Latin ‘ <i>plūma</i> ’, meaning ‘plume’, to describe the radiate appearance of this new hydroid genus. The gender is feminine.</p> Remarks <p>Based on morphological grounds alone, the absence of lateral nematothecae flanking the hydrotheca place this genus in the family Kirchenpaueriidae Stechow, 1921. This allocation should be regarded as provisional, pending the collection of additional material suitable for molecular studies, expected to clarify unambiguously its systematic position.</p> <p> In having hydrocladia provided with two accessory appendages, the colonies of this so far monotypic genus somehow resemble macroscopically <i>Oswaldella</i> Stechow, 1919, but in the latter, the hydrocladia branch dichotomously at the level of the proximalmost internode, the original cladium not extending beyond this internode (Peña Cantero <i>et al</i>. 1997).</p>Published as part of <i>Galea, Horia R. & Maggioni, Davide, 2020, Plumularioid hydroids (Cnidaria: Hydrozoa) from off New Caledonia collected during KANACONO and KANADEEP expeditions of the French Tropical Deep-Sea Benthos Program, pp. 1-58 in European Journal of Taxonomy 708</i> on page 8, DOI: 10.5852/ejt.2020.708, <a href="http://zenodo.org/record/4011061">http://zenodo.org/record/4011061</a>
