						Size moderately small, leg spans to about 5 - 7 cm.  Trunk, lateral processes, and legs covered variously with long and short setae and some covered with pile of short setae.  The long setae rarely have tiny lateral setules as occur in some similar species.  Lateral processes well separated. Neck posterior widest, tapering toward anterior.  Proboscis and abdomen moderately long, without setae.  Chelae fingers long, cutting (inner) edge touching when closed. Movable finger without proximal setose pad (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.
