Proboscis half again as long as the trunk, generally inflated and slightly down curved over most of its length. Ocular tubercle taller than its diameter, eyes small. Palp seventh segment quite long, eighth very short, not as long as wide, with ventral projection, ninth and tenth segments longer, subequal, carried elevated but not recurved. Oviger claw only as long as segment diameter, opposed to enlarged distal denticulate spine, forming subchelate structure. Tarsus and propodus subequal in length, claw about 0.75 propodal length or more (Ref. 9).

Life cycle and mating behavior
পরিপক্কতা | প্রজনন | ডিম ছাড়া | Eggs | ডিম্বধারন ক্ষমতা | 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.
