Ovigers large, segments 3-6 with many lateral setae, seventh with lateral bulge having many setae, strigilis segments small. Legs with many short dorsal spines, low dorsolateral tubercles on the first and third coxae, moderately long sex pore spur on posterior 4 second coxae, and modest dorsodistal tubercle on each femur.

Biology     Glossary (e.g. epibenthic)

Coastal to shelf (Ref. 19). 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).
