Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 0.7 cm LS male/unsexed; (Ref. 6)
Small; leg span 0.65 cm. Trunk: first two segmentation sutures complete, suture lacking between third and fourth segments. Lateral processes: separated by their diameters or less, armed with single dorsodistal seta each. Neck: Very short. Ocular tubercle: broad, only slightly taller than wide, apex a rounded cone, eyes large, darkly pigmented. Abdomen: fairly short, erect, with five or 6 laterodistal setae. Proboscis: short, inflated proximally, lips flat, with low bulges. Chelifores: Short, scapes slender, armed with dorsodistal seta each. Chela: Slender, fingers as long or slightly longer than palm, carried obliquely. Palm: With seta at finger insertion. Movable finger: Well curved distally, overlapping immovable finger, straight with slight distal curve. Both fingers armed with three sharply pointed teeth. Oviger: 6 segmented; third segment longest, with proximal constriction, second and fourth subequal, 0.6 as long as third, armed with several lateral and distal short setae. Fifth segment almost as long as fourth, armed with seven recurved setae. Terminal segment: conical, inflated, almost half length of fifth, armed on endal surface with four recurved setae. Legs: Slender, armed with few setae and long dorsodistal spine on major segments. Second coxae almost twice length of first, third only slightly longer than first Femur almost cylindrical, with slight bulge over cement gland placed slightly proximal to middorsum. Cement gland a single oval cribriform pore. Femur: Longest segment with second tibia slightly longer than first. Tarsus: Semi triangular, short, without ventral spine. Propodus: robust, slightly curved, with low heel bearing three short spines and several setae, sole without spines, few setae, and lamina along entire surface; first leg pair longer than posterior pairs, armed with longer, less-curved claw having narrow sickle-shaped cross section and blunt tip. Claws: Posterior leg pairs shorter more curved, almost round in cross section, with sharp tip. All claws with tiny basal auxiliaries (Ref. 6).
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.
