Proboscis with major distal swelling from midpoint to about halfway to tip. Each dorsomedian trunk swelling sometimes with conical projection. Oviger claw shorter than its segment diameter, with distal spine larger than others in opposition to claw. Tarsus sometimes equal to or sometimes slightly longer than propodus, both with tiny sole spines. Terminal claw very long, usually slightly shorter than propodus but sometimes as long as segment (Ref. 2153, p. 28).

Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | Eggs | Fecundity | Larvae
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.
