P 3 (Fig. 32 A): coxa bare; basis with one outer seta; exp three-segmented (Fig. 36 E); exp – 1 and exp – 2, each with one outer spine; exp – 3 with four spines and one minute seta; enp two-segmented; enp – 1, short, bare; and enp – 2 with three setae. P 4 (Fig. 32 B): coxa bare, basis with one outer seta; exp three-segmented; exp – 1 and exp – 2 each with one outer spine; exp – 3 with four spines and one minute seta; enp two-segmented; enp – 1, short, bare; enp – 2 with one inner pinnate, two apical setae, and outer strong pinnate seta. Armature formulae as follows: P 5 (Fig. 29 A): basal part with one outer bare seta; endopodal lobes not fused medially, connected by an intercoxal sclerite, with five pinnate setae; exp defined at base, with six pinnate setae. P 6 (Fig. 29 B): P 6 vestigial, represented by a small bump bearing two setae. Male. Total body (Fig. 33 A): length from anterior margin of rostrum to posterior margin of caudal rami 1,000 μm, maximum width 165 μm measured at end of cephalothorax. General body shape, ornamentation, and sensilla pattern as in female except for genital double somite; sexual dimorphism in A 1, P 3, P 4, P 5, and P 6. A 1 (Fig. 33 B – D): six segmented, robust, subchirocer; seg – 2 with small blunt process in middle; seg – 4 swollen, with two pad-like processes near anterior margin and two blunt processes: 1 – [1], 2 – [10], 3 – [8], 4 – [12 + (1 + ae)], 5 – [1], 6 – [10], apical ae absent, but two apical setae fused at base. P 2 (Fig. 35 A): similar to the one of female, except for one outer seta on basis shorter than females and innermost seta on enp – 2 longer than females. P 3 (Fig. 35 B): exp same as female; enp developed, three-segmented; enp – 1 short, bare; enp – 2 with long apophysis that apparently tri-segmented apically; and enp – 3 with one bare and two pinnate setae. P 4 (Fig. 35 C): similar to the one of female, except for enp – 2 with one apical (more robust than female), one bare, and two pinnate setae. P 5 (Fig. 34 A): benp represented by a small protrusion with two pinnate setae; exp defined at base with five setae. P 6 (Fig. 34 B): asymmetrical, with functional right member articulating at base and closing off genital aperture, and left member fused at base to genital somite; each P 6 with one bare and one pinnate seta. Caudal rami (Fig. 34 C, D): general shape same as in female; inner lamella ornamented with ten teeth.	en	Back, Jinwook, Bang, Hyun Woo (2026): A new genus of Orthopsyllidae Huys, 1990 (Copepoda, Harpacticoida) from the Pacific Ocean.
