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).

Life cycle and mating behavior
Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | 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.
