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.
