Short description Μορφολογία
Moderately small, leg span about 15 mm.

Neck extending very little anterior to proboscis insertion, ocular tubercle low, at extreme anterior of neck, eyes well defined. Proboscis long, slender, about length of first two trunk segments, bottle-shaped, with long distal bottle neck, tapering at mouth. Abdomen moderately long, extending just beyond first coxae of fourth leg pair. Chelifores slender, short, only about half proboscis length, chelae tiny, with functional fingers. Palps lacking. Ovigers of 6 segments, Anoplodatylus-like, with few short setae. Legs of moderate length, with few short setae. Male femoral cement gland with row of minute pores along dorsal surface. Tarsus very short, propodus robust, with one conspicuous heel spine, few tiny sole spines, robust claw very curved distally, auxiliaries lacking.

Life cycle and mating behavior Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | 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.
