Short description Morphology

This tiny species has a papillose integument an is otherwise quite tuberculate. There are three robust dorsomedian tubercles only slightly taller than their diameters. The lateral processes have low dorsodistal tubercles broader than tall and gradually decreasing in seize posteriorly. The ocular tubercles low, fairly broad, and has an anterior extension projecting about 0.3 of the proboscis length. The eyes are indistinct with very little pigment. The proboscis is typical. The abdomen is fairly long, extending to the distal rim of second coxae on the fourth leg pair. The palps are robust, 4 segmented, slightly longer than the proboscis, and the first or longest segment bears a dorsodistal tubercle slightly longer than its dorsal tubercle just proximal to the distal tip. Distal two segments no longer than their diameters, terminal segment only a tiny knob. The ovigers are typical, with curved terminal claw. Legs are robust, short, first coxae with low rounded tubercle each. Propodus well curved, main claw robust, with short auxiliary claws (Ref. 9).

Biology     Glossary (e.g. epibenthic)

Depth based on occurrence record; to be replaced with better reference. 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 (Ref. 833).
