Child, C.A. 1998. (Ref. 9)
Size / Weight / Age
Demersal; depth range 1373 - 1640 m (Ref. 9)
Climate / Range
Southwest Pacific: New Zealand.
Trunk and neck long, slender, glabrous, lateral processes well separated, less than twice as long as their diameters. Ocular tubercle a small blind cone at extreme anterior of cephalic segment before the long neck, lateral sensory papillae prominent. Oviger bases partly hidden in dorsal view by first lateral processes. Abdomen a short cylinder rounded at tip. Chelifores large, scapes almost as long as proboscis in ventral view, with few short setae, movable finger twice length of immovable finger, both with several low crenulations as teeth. Palps shorter than proboscis, first two segments short, distal two longer, subequal, with few setae, most longer than segment diameters. Oviger typical, fifth segment with small apophysis with 1 - 2short setae. Strigilis with many denticulate spines, terminal claw slender, about half length of terminal segment. Legs slender, very long with few short setae. Second tibiae the longest segments. Tarsus very short, with one major sole spine, several setae. Propodus long, straight, with three major heel spines, 10 - 12 smaller sole spines, and rather short claw auxiliary claws almost as long as main claw (Ref. 9).
Depth based on occurrence record; to be replaced with better reference. 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).
