توصيف مختصر ريخت شناسي
Small; leg span 0.88 cm. Trunk: compact, fully segmented. Lateral processes: only as long as their diameter, separated by half their diameters, glabrous. Neck: short, only as long as width of oviger tubercles. Crop: Anterior to neck wider than trunk, with setae over insertion of chelifore. Ocular tubercle: Slender, slightly less than twice as tall as wide, with two lateral short slender tubercles at apex. Eyes large, filling most of ocular tubercle, darkly pigmented. Abdomen: Short, little longer than ocular tubercle, armed with two distal setae. All anterior appendages: large. Proboscis: massive, inflated at midlength, tapering distally to rounded lips.
Chelifores: very large, scapes robust, straight, armed with dorsal and lateral setae as long as or longer than segment diameter. Chelae: huge, palm globular, greatly inflated, armed with many short setae. Fingers: shorter than palm, set obliquely to palm, very slightly curved with tips not overlapping, without setae, both with closely set bicuspid teeth, anterior cusps longer than posterior points, with 10 or 11 teeth on movable finger, 13 on immovable finger. Palps: trunk, second segment longest, third only 0.6 length of second, terminal segment 0.6 length of third, and fourth slightly shorter than terminal segment. Second segment armed distally with fringe of short setae, fourth with ventrodistal fringe, and terminal two segments with dense ventral and lateral setae, some longer than twice segment diameter. Oviger: segment five the longest segment, slightly inflated distally, without an apophysis, armed ectally and laterally with many setae longer than segment diameter. Segment six slight longer than four, six and strigilis armed with lateral and ectal setae similar to fifth segment. Strigilis: segments small, subequal in length, armed with endal denticulate spines in the formula 10:9:9:10, with a terminal claw almost as long as last segment, very slightly curved, armed with tiny proximal fringe or lamina, without teeth. Legs: slender, second tibia longest major segment, femur slightly longer than first tibia, armed with few long dorsodistal setae and short setae increasing in number distally on leg. Femur: inflated over proximal half, thin-walled. Tarsus: very short, armed with one ventral spine and few dorsal and ventral setae. Propodus; Short, slightly curved, without marked heel, armed with six large heel spines in two rows and six or seven smaller sole spines with flanking rows of short setae. Setae: distally, some longer than propodal diameter. Claw: less than half propodal length, auxiliaries 0.75 as long as main claw, all three with endal proximal row of tiny spinules (Ref. 6).
Life cycle and mating behavior بلوغ | تولید مثل | تخم ریزی | 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.
