Trunk moderately slender, with 2 extremely tall median tubercles, each bearing row of sharp spines mostly on posterior surface. Ocular tubercle only twice as long as diameter, much shorter than median tubercles. Lateral processes long, separated by their diameters, with spinose dorsodistal tubercles and shorter laterodistal tubercles. Proboscis cylindrical, tapering distally. Abdomen long, with ventrodistal bend, bearing 2 short proximal tubercles, 2 long dorsomedian tubercles, and 2 long dorsodistal tubercles, each bearing lateral and distal spines. Chelifore scapes 1 segmented, long, with several setose, short distal tubercles; chelae tiny, vestigial. Oviger segment 4 long, slender; strigilis weak, terminal segment tiny, with 3 broad spines. Legs with extremely long, spinose dorsal and lateral tubercles; propodus straight, with slight heel bearing 2 spines (Ref. 2115, p. 28).

Life cycle and mating behavior
परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | 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.
