Mauritiorchestia fayetta sp. nov.</p> <p>Included species. Mauritiorchestia is currently monotypic.</p> <p>Category. Mascupod.</p> <p>Ecological type. Sand-hopper.</p> <p>Etymology. A compound noun derived from the name of the country and the name of a related genus.</p> <p>Diagnostic description (male).</p> <p>Head. Antenna 1 short, not reaching midpoint of peduncular article 5 of antenna 2. Antenna 2 peduncular articles incrassate. Mandible left lacinia mobilis 5-cuspidate. Maxilla 1 palp absent. Labium without inner lobes. Maxilliped palp article 2 with distomedial lobe; article 4 fused with article 3.</p> <p>Pereon. Gnathopod 1 sexually dimorphic; subchelate; coxa much smaller that coxa 2; posterior margin of carpus and propodus each with lobe covered in palmate setae; propodus anterior margin with 4 groups of robust setae, ‘subtriangular’ with well-developed posterodistal lobe, palm transverse; dactylus simplidactylate. Gnathopod 2 sexually dimorphic; subchelate; propodus palm acute, rounded distally and sinuous, with small to large midpalmar sinus, without proximal sinus, without large distal sinus, without proximal spine or thumb defining palm; without large projection near dactylar hinge; dactylus not modified distally, blunt, fitting into sulcus internally. Pereopods 3–5 cuspidactylate, 6–7 simplidactylate. Pereopod 4 significantly shorter than pereopod 3; carpus significantly shorter than that of pereopod 3; dactylus amplidactylate, thickened proximally with notch midway along posterior margin. Pereopod 6 subequal in length to pereopod 7; not sexually dimorphic; basis moderately expanded; male merus expanded, carpus not expanded. Pereopod 7 not sexually dimorphic; basis broadly expanded, posterior margin smooth or minutely serrate margin without setae, posterodistal lobe present, rounded, produced downwards almost to merus; merus expanded distally, subtriangular, anterior margin slightly straight; carpus expanded, subrectangular, slightly shorter than propodus; propodus slender.</p> <p>Pleon. Pleopods 1–3 all well-developed. Uropod 1 peduncle distolateral robust seta absent; exopod without marginal robust setae; endopod with marginal robust setae in 1 row. Uropod 2 exopod without marginal robust setae; endopod with marginal robust setae in 1 row. Uropod 3 ramus subequal in length to peduncle. Telson completely cleft, with 6 robust setae per lobe.</p> <p>Remarks. Mauritiorchestia is a distinctive Indian Ocean genus. Based on an incrassate second antenna, gnathopod 1 with palmate lobes on the carpus and propodus and uropod 1 exopod without marginal robust setae, it is most similar to the north-western Pacific genus Sinorchestia Miyamoto &amp; Morino, 1999 and the wide-ranging genus Platorchestia Bousfield, 1982. Sinorchestia differs significantly from Mauritiorchestia in having a ventral plate on the third peduncular article of antenna 2, a parachelate first gnathopod and a large posteroproximal sinus on the dactylus of gnathopod 2. Platorchestia differs from Mauritiorchestia mainly in having a cuspidactylate first gnathopod and the exopod of uropod 2 with marginal robust setae in one row.</p> <p>Distribution. Mauritius, Western Indian Ocean.</p></div> 	http://treatment.plazi.org/id/03AD87EFF21BC21CFF72FB0EFD60806E	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.
