Palaemon styliferus [Status Unaccepted]   H. Milne Edwards,  1840 (Prawn)
Organism information awaits expert curation
Class: Malacostraca

Rostrum long, reaching beyond apex of antennal scale; proximal portion strongly elevated dorsally forming a prominent basal crest which bears 5 to 7 teeth; slender in front of the crest and upturned; usually unarmed for the greater of its length, but near the tip as a rule, provided with 1 to 3 small widely separated teeth; lower margin with 6 to 10 teeth. Antennal spine small and inconspicuous and the branchiostegal much larger, above which is a finely cut groove. The greatest breadth of the cornea about equal to the length of the eye-stalk. A small ocellus visible partly jointed to the cornea. Basal segement of antennular peduncle with a small spine on the lower surface. Outer border sinous in front of the short spine representing the lateral process, and terminates in a tooth which extends but little beyond the level of the protruding setose antero-external margin of the segment. The second segment, measured mid-dorsally is a little more than half the length of the third. Total length of the shorter branch of outer antennular flagellum is about equal to that of peduncle. Antennal scale broad and 3 times as long as wide; the rather sharply rounded distal end of lamella extending much further beyond the spine at the outer margin. Mandibular palp 3 segmented; third maxilllipeds reaching about to the end of antennal peduncle; the antepenultimate segment less expanded distally and the exopod reaching to its anterior quarter. First peraeiopods reach almost to the end of antennal scale. The merus and carpus about equal; chela barely 3/5 the length of carpus. Ischium, merus, carpus and pal decreases successively in length in most individuals, but in very large males the carpus sometimes equal to, or a little longer than the merus; carpus always shorter than chela. Last 3 pairs of legs slender and usually bear short setae on the posterior margin of the ischium, merus and propodus.
Abdomen smoothly rounded above in small example, but in those of large size, sometimes a blunt and inconspicuous dorsal ridge extending from the middle of 3rd somite to the end of the 6th. Sixth somite, dorsally less than half the length of carapce. Telson reaches to about 3/4 the length of outer uropod; it bears 2 pairs of minute spinules in its distal half. The apex in large specimens is simply pointed, without trace of lateral spinules; in smaller, but still adult specimens 2 pairs of very small spinules may be found not reaching the tip. Outer uropod is narrow, about 3 times as long as broad. Young prawns are with shorter rostrum.
