Proboscis very long, swollen proximal to including midpoint, extremely slender (pipette-like) distal to swelling, upturned toward tip. Lateral processes short, well separated. Palps moderately short, little longer than proboscis, distal three segments subequal. Legs very slender, distal segments small, tarsus longer by 1.5 times than short propodus, claw tiny (Ref. 9); Proboscis very slender, medially swollen, tapering distally, slightly upturned (with variation in the low angle of upturn) and much longer than trunk. Palp segment 5 much longer than segment 3, sixth and seventh are subequal, distal 3 much shorter than sixth or seventh and subequal to each other. Legs very slender, tarsus about 1.4 to 2.0 times longer than propodus, terminal claw about half as long as propodus (Ref. 2153).
Bathyal to abyssal (Ref. 19).
生命週期和交配行為

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.
