Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Proboscis very narrow, long and straight. It is nearly twice the trunk diameter and has a very little median swelling. Ocular tubercle a low bump, eyes indistinct. Seventh palp segment very long, slender, eighth segment semi triangular, with ventral tubercle or extension, ninth subequal to eighth, tenth twice as long, both carried recurved dorsally. 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
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.
