North Pacific: Alaska, Japan, Russian Federation and Bering sea (Ref. 2153). Subtropical to Boreal.
Trunk circular in dorsal outline, lateral processes separated by tiny intervals, armed with paired low dorsodistal tubercles bearing setae. Ocular tubercle twice taller than its diameter, eyes prominent. Proboscis typical. Abdomen long, extending to distal tip of second coxae, fourth leg pair. Chelifore scapes moderately long, slender, equal to first and second palp segments in length. Palp second segment equal in length to fourth, otherwise typical. Oviger seventh segment with many lateral setae longer than segment diameter. Legs moderately long, armed with many tiny short ventral setae and fewer longer dorsal setae. Propodus fairly short, armed with 3 to 4 heel spines and 10- I2 shorter sole spines, auxiliary claws about 0.6 length of main claw (Ref. 2153, p. 3).
Shelf (Ref. 19). Members of the class Pycnogonida are gonochoric and sexually dimorphic. During copulation, male usually suspends itself beneath the female. Fertilization occurs as the eggs leave the female's ovigers. Males brood the egg masses until they hatch. Life cycle: Eggs hatch into protonymphon larva then to adults (Ref. 833).
