Maturiteit: Lm ?  range ? - ? cm
Trunk robust, lateral processes short, little longer than diameters, separated by less than diameters, with few short posterodistal setae. Ocular tubercle very low, eyes filling most of tubercle. Proboscis short, cylindrical, oral surface rounded. Abdomen moderately short, erect. Chelifore scapes robust, slightly curved, chelae palms robust, fingers shorter than palm, with small short teeth. Palps quite short, second segment only about 3 times longer than its width, distal segments each shorter. Legs moderately long, with many short setae and spines, few longer than segment diameters. Tarsus almost as long as propodus. Propodus with 5 larger sole spines, several smaller distal spines. Auxiliary claws little less than half main claw length. Appendages show much variability (Ref. 2153, p. 20).

Levenscyclus en paargedrag
Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven
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.
