BA5587CEC134FFB813620109BD8FB6B6.taxon	discussion	Remarks. Elaphognathia sugashimaensis was described by Nunomura (1981) based on the specimens collected from the Sugashima, Ise Bay, Japan. This species was redescribed by Muller (1989), who provided a more detailed morphological description of the cephalon, and the species has been previously reported from Japan only. Elaphognathia sugashimaensis is similar to E. lucanoides (Monod, 1926) in external features. Howev­ er, E. sugashimaensis differs from E. lucanoides in having a less excavated cephalon and more robust mandible (Muller, 1989). This species is also similar to E. discolor. However, E. sugashimaensis differs from E. discolor in having 3 ­ articled pylopod (2 ­ articled pylopod in E. discolor). In general, the illustrations and descriptions of E. sugashimaensis specimens from South Korea agreed well with the illustrations and original description of Nunomura (1981) and redescription of Muller (1989). Habitat. This species was found on the surface of an ascidian, Pyura sacciformis, at the type locality. The specimens were collected from the sandy bottom with seaweeds at a depth of 3 ­ 5 m.

BA5587CEC137FFB9130C0010BB76B2DF.taxon	discussion	Remarks. Metacirolana shijikiensis was described by Nunomura (2008) based on the specimens collected from the Mouth of Shijiki Bay, off Ehonohana, Japan. This species has been previously reported from Japan only. Metacirolana shijikiensis is similar to M. chemola Schotte & Kensley, 2005 in external features. However, M. chemola differs from M. shijikiensis in having two short, stout spine­like setae and simple setae on lateral margin on uropodal exopod and one stout spine­like seta and long simple setae on lateral margin on uropodal endopod (uropodal exopod and endopod with no spine­like setae, but marginal setae in M. shijikiensis). This species is also similar to M. agaricicola Kensley, 1984. Howev­ er, M. shijikiensis differs from M. agaricicola in having a convex posterior margin on pleonite 5 (trilobed margin on pleonite 5 in M. agaricicola). In the original description, the third article of the maxillipedal palp is not expanded and similar length to other articles. We believe that the description of the maxillipedal palp was inaccurate, because all species of the genus Metacirolana have an expanded article 3 on the maxillipedal palp as a generic characteristic (Brusca et al., 1995). In general, the illustrations and description of M. shijikiensis specimens from South Korea agreed well with the illustrations and original description of Nunomura (2008). Habitat. There is no information on the habitat at the type locality. The specimens were collected from the sandy bottom with seaweeds at a depth of 3 ­ 5 m. World distribution. Japan (Nunomura, 2008), Korea.
