Oviger terminal segment with enlarged distal denticulate spine forming subchela with moderately long curved terminal claw. Femora the longest major leg segments. Tarsus slightly longer than propodus, claw long, variable, sometimes longer than propodus (Ref. 9).

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.
