Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Trunk: circular in dorsal outline, segmentation lines lacking first or second segments divided by line. Trunk and appendage spines with bifurcate tips, some trifurcate. Lateral processes: smooth, with small setae, touching for their lengths. Ocular tubercle: short, eyes prominent. Palp: distal 3 segments carried anaxially on extended 5th segment. Oviger strigilis: with setae but with small denticulate spines. Coxa: 2 distally swollen in females, with ventrodistal spur in males. Major leg: segments with longer than dorsal and lateral spines and few short setae. Tarsus: typical, very short, well curved, with 4, 5, or 6 larger heel spines, 8-10 small sole spines, claw and auxiliaries typical, robust (Ref. 9).
New Zealand and Sub Antarctic Islands, from 0 to 50 m. The Mahai Peninsula, shallow waters of South Island and its offshore island; endemic (Ref. 9).
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.
