Proboscis long, 8 to 9 times its maximum diameter, swollen at midpoint, which is widest area, and is straight, linear, or with a slight dorsal curve distally. Curve variable and usually not conspicuous. Distal 3 palp segments together no longer than next proximal or 7th segment, and 6th segment only about 0.75 as long as 7th. Terminal palp segment longer than penultimate 2 which are subequal in length. Tarsus varies from 2.5 to almost 3 times longer than slender tapered propodus. Claw relatively short at about 0.33 of propodal length. Species blind with low, anterior-pointing conical ocular tubercle (Ref. 2157, p. 11).
Abyssal (Ref. 169).
Life cycle and mating behavior
половая зрелость | размножение | нерест | Eggs | Fecundity | 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.
