Mursia australiensis Campbell, 1971

(Fig. 1F)

Material examined. 1 juv. female (with colour image), 19.5 (14.0 without lateral spines) × 13.0 mm (ZRC 2020.0755), stn CP02, Sunda Strait, southwest of Rakata Island, 6°16.066′S 105°15.053′E – 6°14.668′S 105°15.256′E, 257–281 m, very muddy with some clay, 24 March 2018; 1 juv. female (with colour image), 17.5 (12.6 without lateral spines) × 11.6 mm (ZRC 2020.0756), stn CP34, western Java, south of Tanjung Boyongkareuceng, 7°44.464′S 107°39.018′E – 7°44.575′S 107°39.447′E, 243– 234 m, gravel with pieces of wood, 29 March 2018.

Remarks. Both specimens collected were small, immature females but their morphology matched most closely with the description of Mursia australiensis Campbell, 1971, particularly in the general outline and orientation of the carapace lateral spine which is directed laterally and slightly posteriorly, as well as in having three spines on the posterior margin of the cheliped merus, with the distalmost spine nearly as long as the lateral spine of the carapace. Furthermore, the Indonesian material also had a single fissure on the supraorbital margin, a V-shaped suborbital sinus, and a tridentate posterior carapace margin wherein the median tooth is smaller than the lateral teeth (cf. Campbell, 1971: fig. 1, pl. 2 figs. A, B; Galil, 1993: figs. 1d, 2g, h, 11). The live colouration of the specimens from Indonesia mostly agrees with published figures (Miyake, 1983: pl. 8 fig. 5; Galil, 1993: fig. 11) in the general colour pattern, particularly in having the large tubercles on the dorsal carapace surface basally cream or tan, and the smaller granules reddish-orange, although the inner surface of the cheliped palm has a much larger patch of reddish-orange (Fig. 1F). Mursia australiensis has been previously recorded from Cape Morton, Queensland, Australia (type locality) as well as from New Caledonia, and possibly Japan (Galil, 1993). This is the first record for this species in Indonesia.
