Lysiosquillina maculata ( Fabricius, 1793)

Squilla maculata Fabricius, 1793: 511 . Type locality: Indonesia.

Lysiosquilla maculata – Manning 1978a: 3-7, figs 1-3, 9. Lysiosquilla sp. 2 – Michel 1970b: 57, 58, fig. 2D, F, fig. 3A, B, tab. 1.

MATERIAL EXAMINED. — Eiao, stn CP1158, 7°58.7’S, 140°43.9’E, 109-110 m, 23.VIII.1997, 1 late pelagic larva, tl 30. — Stn CP1159, 7°50.3’S, 140°43.7’E, 145 m, 23.VIII.1997, 1 late pelagic larva, tl 33 ( MNHN). — Nuku Hiva, stn DW1279, 7°59.4’S, 140°42.2’E, 23-70 m, 06.IX.1997, 1 juvenile tl 29 ( MNHN), 1 tl 210 ( USNM 6593).

DISTRIBUTION. — Widely distributed in the Indo- West Pacific from the western Indian Ocean to the central Pacific. Manning (1978a) previously reported L. maculata from the Marquesas.

MEASUREMENTS. — Male (n = 2) tl 29-210, late pelagic larvae (n = 2) tl 30-33.

REMARKS

The male juvenile agrees well with adults in most characters including broad antennal scales, nine or 10 teeth on the dactylus of the raptorial claw, a blunt sternal keel on TS8, a carinate rostral plate and colour pattern, including the dark apex on the uropodal endopod. The juvenile differs from adults in that the dorsal processes on the antennular somite are directed anterolaterally (as in adult Lysiosquilla sulcirostris Kemp, 1911 ) instead of anteriorly and the mandibular palp is 1- instead of 3-segmented. The late pelagic larva agrees well with the account and figures of larvae attributed to L. maculata by Michel (1970b). Lysiosquillina sulcata also occurs in French Polynesia (Steger & Benis-Steger 1988), and it is possible that in postlarvae and juveniles, the morphology of the rostral plate, diagnostic for L. sulcata , could resemble juvenile L. maculata ; L. maculata differs, however, in bearing a dark instead of light apex on the uropodal endopod.
