Description
Styraconyx qivitoq Kristensen & Higgins, 1984
N= 13 specimens: 13 males occurrence: ANDEEP-SYSTCO; 1,927–1,960 m bsl.
Figs 10A–E; Supplementary Table 1.10
Short description
We observed only dwarf males (72–108 µm long) unique for this species. Ovoid primary clavae and long cephalic cirri present (Fig. 10A). Secondary clavae are present (Fig. 10B). Neck region with folded cuticle (Fig. 10C). All digits are covered with a cuticular hood. Peduncles are large (Fig. 10D). Inconspicuous tubular-shape male gonopore is present (Fig. 10E).
Remarks
All the described characters are species-specific and correspond well to the original description (Kristensen & Higgins, 1984), so the identification is sound.
