Ocular tubercle well developed with large anterior pair of eyes, posterior pair either inconspicuous or lacking. With two of above males , anterior pair of eyes quite conspicuous but slightly pigmented, smaller posterior pair of eyes present but very inconspicuous, apparently unpigmented. Lateral processes well separated in quite slender species. Terminal palp segment shorter than penultimate segment. Oviger claw short, without teeth, no longer than distal denticulate spines of terminal segment. Spines with either two or three lateral lobes. Propodus shorter than slender tarsus with terminal claw little more than half length of propodus. Male cement gland apertures several inconspicuous ventral pores on femorae (Ref. 2157, p. 7).

Biology     Glossary (e.g. epibenthic)

Bathyal to abyssal (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).
