Processa sulcata Hayashi, 1975: 134 , fig. 34.—Noël, 1986: 291, fig. 19.—Chace, 1997: 39.—Kim et al., 2011: 265, fig. 2.

Material examined. Australia: 1 female (pocl 2.4), FLMNH UF 25889, Great Barrier Reef, Heron Island, - 23.4284 151.9546, leg. J. Reimer, 25.11.2006 [AUST-6507, HI09-104].

Colour pattern. Semitransparent with patches of white chromatophores (some on internal organs), especially dense on and near tail fan, and patches of red chromatophores, mainly on carapace, third maxilliped, first pereiopods, bases of fifth pereiopods and pleopods, and tail fan ( Fig. 7 B).

Remarks. The single individual from Heron Island presents no special morphological features, fitting the diagnosis of P. s u lc a ta in Hayashi (1975).

Ecology. The ecology of P. s u l c a t a is poorly known, with the present record not alleviating this situation. Most of the literature records are from dredged material, with no information on bottom characteristics. Hayashi (1975) states that P. s u l c a t a was collected from “seaweed and sessile marine invertebrates, which get entangled in the gill nets used for fishing spiny lobsters”, and also indicates it to be present in seagrass beds. However, the species does appear to have a considerable depth range, 0–123 m (Chace, 1997).

Distribution. The species is widespread in the Indo-Pacific, with records from South Africa, Arabian Sea, Java, Vietnam, Japan (Hayashi 1975), Madagascar (Noël 1986), Hong Kong (Bruce 1990), Queensland (Davie 2002), the Persian Gulf ( De Grave 2007; De Grave & Ashelby 2011) and Korea (Kim et al. 2011). The inclusion of “South America ” in the distribution for P. s u l c a t a by Chace (1997) is considered a lapsus for South Africa.
