Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Integument strongly reticulate; trunk segments 1 - 3 with well-defined, rounded processes. Oviger male only, 7 segmented. Propodus approximately equal to length of femur. Tibia 2 shorter than wide. Propodal sole spines cleft at apex, loosely arranged in narrow field along length of propodal sole. Auxiliary claws absent (Ref. 860).

Life cycle and mating behavior
Maturity | Reproduction | Spawning | 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.
