Description
Carapace (Fig. 8a) with frontal margin slightly oblique; anterior spine not reaching sinus level between rostrum and supraocular spine; posterior branchial margin with five spines; no scale-like or short stria on intestinal region. Second pleomere (Fig. 8a) with two spines on each side of anterior transverse stria. Sternal plastron (Fig. 8b) with few striae on fourth sternite; anterior margin of fourth sternite contiguous to median part of posterior margin of third sternite. Eyes (Fig. 8a) large. Basal segment of antennular peduncle (Fig. 8c) with terminal spines subequal. First segment of antennal peduncle (Fig. 8d) bearing distomesial spine almost reaching distal margin of third segment; second segment bearing small mesial spine and prominent distomesial spine overreaching distal margin of fourth segment. Merus of third maxilliped (Fig. 8e) bearing distinct distal spine on extensor margin; flexor margin with three spines. First pereopod (Fig. 8f) with fingers as long as palm, each bearing proximal spines fairly dorsal, and between subterminal and basal spines. Flexor margin of dactylus in second pereopod (Fig. 8g) bearing corneous spines in proximal two thirds and unarmed on distal portion.
Coloration
Generally orange red; chelipeds with whitish lateral margins and reddish mesial margins; ambulatory legs with slight reddish brown and white bands (Fig. 11g).
Distribution
Korea, Japan, East China Sea, Taiwan, Philippines, and Indonesia; depth 22-732 m (Stimpson 1858, Miyake and Baba 1967, Macpherson and Baba 1993, Wu et al. 1998, Komai et al. 2002, Baba et al. 2009).
Remarks
M. japonica is easily distinguished from its two Korean congeners, as it has two spines on each side of anterior ridge of the second pleomere and few striae on the fourth and fifth thoracic sternites. Macpherson and Baba (1993) clarified the taxonomy of M. japonica designating a neotype, as previous records of this species comprised incorrect identifications. Although Kim (1973) recorded M. japonica from Korea, it is difficult to fully assess the identity of the materials used by this author without reexamining them. Thus, Kim’s (1973) record is questionably included in the synonymy. Nevertheless, the present study confirms the occurrence of M. japonica in Korea. This species is widely distributed in Korean waters from Busan to western Jeju Island.
