Paranthura urodentata sp. nov.

( Figure 40)

Type material. HOLOTYPE: USNM 253180 , non-ovigerous m 8.1 mm, sta K-SEY-16, algal turf on boulders, Anse aÁ la Mouche, Mahe Is., Seychelles, 2±5 m, 1 May 1984 . PARATYPES: USNM 253181 , one non-ovigerous m 6.5 mm, same data as holotype . USNM 253182 , two juveniles, sta K-SEY-23, algal turf on reef crest, Anse Marie Louise , Mahe Is., Seychelles, 0.5 m, 25 February 1989 .

Diagnosis. Female: Telson evenly elongate±ovate, widest at midlength, with cluster of setae on posterior margin. Antennular ¯agellum of six articles. Pereopod 1, propodal palm convex with low proximal lobe, bearing subpalmar row of about 28 setae on mesial surface. Pereopods 2 and 3, propodus slightly expanded, with eight sensory setae on faintly convex palm. Posterior pereopods with anterior margin of carpus slightly shorter than posterior; propodus bearing ®ve sensory setae and several fringed scales on posterior margin. Pleopod 1, endopod about 0.6 times length of exopod, distal half narrow, bearing four distal plumose marginal setae. Uropodal exopod about 2.7 times longer than greatest width, apically acute, lateral margin dentate, with clumps of setae between teeth; endopod subcircular.

Male: Antennular ¯agellum of six articles, aesthetascs present on 2±6.

Remarks. The combination of a subcircular uropodal endopod and an elongate± ovate uropodal exopod bearing about 12 teeth on the lateral margin, separate this from all previously described species.
