Short description Morphology

Trunk fully segmented. Lateral processes separated by their diameters or slightly more, glabrous. Neck moderately short; large oviger implants at posterior, touching first lateral processes. Ocular tubercle as low rounded bump, without eyes; sensory papillae prominent. Proboscis long; slightly swollen cylinder just distal to midpoint; lips flat. Abdomen short, not as long as first coxae; distally downcurved to be almost vertical at tip, glabrous. Chelifores massive, glabrous, cylindrical scapes slightly longer than proboscis. Chelae curved inward; palms cylindrical, shorter than slender fingers. Movable finger with about 70 long and short teeth; slightly longer than immovable finger with 63 - 64 teeth uneven sizes. Palps slender; third segment only little shorter than second; fourth and fifth with 3 short distal setae; oviger of fourth segment curved, with small low lateral tubercle at about 0.3 its length; fifth segment longest, straight. Strigilis segments each successively smaller, armed with denticulate spines in the formula 15: 12: 10: 9; with a straight terminal claw the same length or slightly longer than the terminal segment, armed with 13 long slender teeth. Denticulate spines long, with 4 lateral lobes on each side. Legs long, glabrous; second tibiae the longest segment. Propodus only slightly longer than tarsus; both slightly curved, unarmed. Claw straight; about 0.75 length of tarsus.

Biology     Glossary (e.g. epibenthic)

Large conspicuous species. 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 (Ref. 833).
