Short description Morphology

Small; leg span 1.05 cm. Trunk: suture lines complete for first and second segments, lacking between third and fourth segments. Lateral processes: robust. Longer than their maximum diameters, separated by half their diameters or less, armed dorsodistally with low rounded tubercle slightly longer than wide on each, flanked by two or three short setae. Neck: Long, constricted posterior to ocular tubercle, "glabrous. Ocular tubercle: twice as long as wide, constricted and rounded apical. Eyes: Large, at tubercle midpoint. Darkly pigmented. Abdomen: moderately long, tapering to rounded tip, armed with two laterodistal setae. Proboscis: Slender, cylindrical over most of length, constricted proximally and distally, lips flat. Chelifores: Long, scapes cylindrical, armed with few lateral, ventral and distal setae. Chela: Long, fingers slightly shorter than palm. Palm: with several distal setae, movable finger well curved, with two proximal setae, immovable finger less curved, with one proximal seta. Fingers: Overlap at tips when closed, without teeth. Oviger: 6 segmented, third segment longest, with proximal constriction, second segment 0.6 as long as third, both armed with few lateral setae. Terminal two segments subequal to length of fourth. Fifth and tiny sixth segments armed with dense setae, some as long as segment diameters. Legs: long, slender, setose. Second coxae of posterior four legs with long ventrodistal spur with apical sex pore, almost as long as segment diameter, with few ventral and distal setae. Femur: Longest segment; with four long dorsodistal setae, shorter than segment diameter. Cement gland: With short tube, equal in length to 0.25 of segment diameter. Second tibia slightly shorter than first, both armed with long dorsodistal seta. Tarsus: short, without ventral spine. Propodus: With large heel bearing two short spines and four distal setae. Sole: With seven or eight low broad spines, two long distal setae and very short lamina. Claw: Well curved, about 0.6 as long as propodus, auxiliaries tiny (Ref. 6).

Life cycle and mating behavior Maturity | Reproduction | Spawning | 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.
