Huge species with short legs. Proboscis much like preceding species, Colossendeis microsetosa Hilton, in length, swellings, and slight distal downcurve. Species blind, ocular tubercle a low broad mound with slight depression at midpoint. Lateral sensory papillae not evident. Abdomen slightly longer than distal rim of first coxae, fourth legs and carried below horizontal. Oviger terminal claw broad, not as long as segment diameter. Distal palp 5 segments of different lengths in relation to each other with seventh the longest, sixth next shorter, and eighth, ninth, and tenth each successively shorter. Legs slender and short in comparison with others of genus. Tarsus about 1.4 times longer than slender propodus. Terminal claw about 0.25 times propodal length. Both tarsus and propodus glabrous (Ref. 2153, p. 28).
Abyssal (Ref. 19).
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.
