توصيف مختصر ريخت شناسي
Tiny, leg span only 0.45 cm. Trunk: Unsegmented, circular in dorsal outline, lateral processes contiguous, without tubercles or adornment. Anterior of cephalic segment only extending little beyond circle of lateral processes. Ocular tubercle: Broad and tall, capped with narrow spike-like tubercle at apex, anterior pair of eyes slightly larger than posterior pair, only slightly pigment. Abdomen: Arise well anterior to midline of third lateral process, erect, not extending posterior to tips of fourth lateral processes, with four short distal setae. Proboscis: narrow, broad flat lips. Chelifore: Single segment short, blunt, extending about as far as second palp segment, with three distal setae. Palp: five-segmented, with single seta on second segment, several on third, three on fourth and s tuft of setae longer than segment diameter ventrally and distally on fifth segment. Third segment longest, fourth only slightly longer than its diameter, fifth 0.6 as long as third. Oviger: Second, third, and fourth segments subequal in length, fifth longest, curved, with several distal setae. Sixth armed with one or two ectal setae and strong recurved spine proximally, seventh with ectodistal row of three setae as long as segment diameter, eighth and ninth with five and two setae respectively in same place. Endal spines: Tenth with tiny spines having distal denticulations. Oviger: Without seventh segment apophysis. Leg: typical, robust, with few short and long setae, none as long as segment diameter. First coxae with bifid anterolateral tubercles bearing setae. All coxae with few short ventral setae. First and second tibiae with dorsal swellings bearing setae. Femoral: cement gland tube very short, tapering, placed dorsodistally. Tarsus: very short, bearing three ventral spines. Propodus: Robust, slightly curved, low heel armed with 3 broad spines, sole with eight or nine short seta. Claw: Short, broad, less than half propodal length, auxiliaries slender, about 0.36 main claw length. Female paratype slightly larger in all measurements except oviger (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.
