Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Male unknown. Female: Trunk compact, fully segmented, glabrous; lateral processes separated by half their diameters or less, only little longer than their width. Cephalic segment very broad anteriorly at chelifore insertion; ocular tubercle low, rounded; eyes prominent. Proboscis very broad, short, swollen distally, with many short distal setae. Abdomen long, carried horizontally. Chelifores very large; scapes 2-segmented; chelae large; palms short; fingers very long, carried anaxially on palms, without teeth. Palp buds oval, I-segmented.

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.
