REMARKS

The colour pattern of the present specimens generally agrees well with holotype of R. komaii . The paired dark “eye spots” on the carapace, however, are surrounded by irregular white patches, most of which unite to form a continuous white ring. In one specimen ( Fig. 6A ), the pattern of white patches approaches Borradaile’s (1898) figure for R. oxyrhyncha ( Borradaile, 1898) , whereas in another from the same locality (CP1264, female postlarva), the pattern of white patches is less irregular but most unite to form a near continuous white ring, closely resembling the holotype of R. komaii from New Caledonia. In the present specimens, as in the holotype of R. komaii , the general body colour pattern is darkly mottled with transverse rows of pale diffuse spots on each thoracic and abdominal somite, TS6 and 8 bear a dark patch at the base of each pereiopod and TS7 bears at most a faint trace of pigment at the base of the pereiopods.

The postlarvae of R. komaii closely resemble those of Pseudosquilla oculata (based on accounts in Bigelow [1931] and Manning [1977]) and are difficult to distinguish. Aside from colour pattern, the present specimens differ from accounts of post-larval P. oculata in bearing posterolateral spines on AS 4-5 instead of AS 5 only, and the margins of the rostral plate are slightly concave, rather than convex as figured by Manning (1977) for P. oculata from the eastern Atlantic. The large size of postlarval R. komaii suggests that this species settles at a considerably larger size than do R. ornata (Miers, 1880) , R. hieroglyphica ( Manning, 1972) and P. ciliata ( Bigelow 1931; Manning 1972, 1977) in which postlarvae are reported at less than tl 25.
