Diagnosis: A species of the aesopius species group. The only species so far described with a simple ambulatory dactyl and ambulatory propods with long distoventral spines..
Description. The specimen now lacks both second pereiopods and three ambulatory pereiopods. The rostrum (Fig. B) is strongly arched, reaching to the middle of the distal segment of the antennular peduncle, about 0.9 of the CL, elevated at about 15°, with a dentition of 8/2, the two distal ventral teeth being quite small.. The carapace (Fig. A) has an epigastric spine well removed from the posterior rostral tooth. The third abdominal tergite (Fig. A) is not produced or carinate; the sixth abdominal segment and caudal fan are detached. The cornea (Fig. C) is globular, about 0.23 of CL, with a distinct accessory pigment spot. The third ambulatory pereiopod has the semi-detached dactyl (Fig. E) slender, about 6.0 times longer than the basal width, with a distinctly demarkated unguis about 0.4 of the corpus length, without distoventral accessory tooth; propod (Fig. D) slender with single long preterminal distal ventral spine, about 1.3 times width of distal propod, propod about 4.5 times longer than dactyl, 13.0 times longer than distal width, with single long preterminal distoventral spine and longer distal ventral spine, about 0.6 of dactyl length, with two more proximal ventral spines, most proximal spine small, more distal spines longer, broken.
Colouration ( Fig. 14D). (From colour photo). The freshly caught specimen is a pallid translucent whitish colour, dorsal carapace with yellowish tinge, with a small reddish patch on the third abdominal tergite, the proximal parts of the caudal fan a more rusty red, with the distal two thirds of the telson white, and the distal ends of the uropods also reddish. The rostrum, scaphocerite, antennal peduncle and appendages are transpar- ent, cornea white, first and second pereiopods with fingers, distal carpus and merus violet, palm and proximal carpus of first pereiopod greenish, palm of second pereiopod white, ambulatory propod distally violet.
Remarks. The single specimen ( Fig. 9) agrees well with the original description by Kubo (1951) and also with the illustrations of Li et al. (2005), particularly with reference to the absence of a distinct dorsal carina on the third abdominal somite ( Fig. 9A) and the long distal ventral spines on the ambulatory propod ( Fig. 9D), with the single distalmost spine being rather preterminal (see Li, et al, 2005, fig. 33c).
Distribution. Not previously reported from Australian waters. Type locality, Sagami Bay, Japan, and also reported from the South China Sea.
