Palaemonella crosnieri Bruce, 1978

Palaemonella crosnieri Bruce, 1978: 210 , figs. 2–4; 2007: 122. — Li, 2000: 101, fig. 108; 2008a: 217. — Li and Bruce, 2006: 656 .

Material examined. St 17, 10/11/2009, 11h–14h, North reef, 12°34'49.93"S, 45° 5'52.62"E, coll. KUW fieldwork, scuba diving 22 m, sediment suction pump, 1 male (LC 2.5 mm), (both second pereiopods lost, distal half of telson lost, rostral formula: 1+5/2) MNHN-Na 17558; St 23, 13/11/09, 11h–13h, Choizil pass "Patate à Teddy", 12°40'56.91"S, 44°57'51.63"E, coll. KUW fieldwork, scuba diving 15–30 m, collapsed edge reef, 1 male (LC 2.5 mm), (rostral formula: 1+6/2), MNHN-Na 17570.

Distribution. Type locality Iles Glorieuses. Also known from Kenya, Australia (Western Australia), Loyalty Islands, Polynesia, Marquesas Islands.

Remarks. The specimens with their rostral formulae 1+5/2 and 1+6/2 seem closer to Palaemonella disalvoi Fransen, 1987 , not 1+7/3 as in the type of P. crosnieri . However, their other characteristics agree with the description and illustrations of Bruce (1978), and the type locality of P. crosnieri is Iles Glorieuses, 20m, and known also from Loyalty Islands, 2–40m ( Li and Bruce, 2006), West Australia (Bruce, 1992, 2007), Marquesas Is., Polynesia ( Li, 2008a), its range is much wider than that of P. disalvoi , which is known only from its type locality Easter Island at 36 m (or 15–60m, DiSalvo et al., 1988). We herewith tentatively treat this specimens as P. cro s n ie r i, although their rostral formulae do not agree with the type. The species was not previously recorded from Mayotte. The specimen of MNHN-Na 17558 was collected together with 1 female of Cuapetes ensifrons (Dana, 1852) (MNHN-Na 17557) at Station 17.
