Trunk: fully segmented with long neck and closely spaced lateral processes. Tall dorsomedian trunk tubercles have 2 to 3 long lateral setae, ocular tubercle at extreme anterior of segment is tall slender cone without eyes, with pair of long setae flanking posterior base. Anterior of cephalic segment flaring, with low tubercles each having short seta which match dorsodistal rims of lateral processes. Some short setae on anterior and posterior of each lateral process. Proboscis: large, ovoid, without constrictions. Abdomen: moderately long, distally swollen, bearing 2 to short dorsal setae. Chelifores: very short, scapes 2 segmented, first segment extremely short, hidden by cephalic segment hood, both armed with several long setae. Chelae: atrophied, tiny slender cones with lateral stub representing movable finger. Palps: typical, 9 segmented. Ovigers: Ammothella-like, with non-functioning strigilis having 2 to 3 slender denticulate spines. Terminal: segment not longer than wide. Legs: long, slender, with many long lateral and dorsal setae. Propodus: slender, well curved, with 3 larger heel spines and many smaller sole spines. Claw: quite long, strongly curved, auxiliaries very short. Male cement gland tube: not within conical tubercle, situated at about 0.6 length of femur dorsum, angled distally (Ref. 9).

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.
