FF1E9C42FF81C144FF1AFE6FFDA07E68.taxon	discussion	Remarks. Kussakin (1962) suggested that the genus Caecijaera could be divided into two groups: the Caecijaera group with 6 - articled antennula, greatly reduced mandibular molar process, and not coiled appendix masculina (incl. C. horvathi, C. cojimarensis, and C. kussakini); and the Caecijaeralla group with 5 - articled antennula, welldeveloped mandibular molar process, and long and coiled appendix masculina (incl. C. borealis, C. derjugini, and C. mirabilis) (Kussakin 1962; Cooke 1977; Svavarsson 1982; Malyutina 1994; Wilson & Wägele 1994; Ortiz 2020). According to this criterion, the new species can be nested within the Caecijaera group (Menzies 1951 a; Kussakin 1962; Malyutina 1994; Ortiz 2020). However, the new species differs from other members of the Caecijaera group by having large simple setae near the midline of the posterior tergite margins of pereonites 4 – 7 (vs. lacking large simple setae in pereonite VII), and proximolaterally angled pleotelson (vs. proximolaterally rounded) (Menzies 1951 a; Malyutina 1994; Ortiz 2020). The indistinct distolateral lobes of pleopod Ⅰ in males is a key to distinguishing the new species from the Hawaiian materials of C. horvathi (vs. long distolateral lobes).	en	Kim, Sung Hoon, Kim, Jong Guk, Yoon, Seong Myeong (2022): Description of two new janirid isopods (Isopoda, Asellota, Janiridae) from Korean waters.

FF1E9C42FF84C14AFF1AFF54FCAF7CE0.taxon	discussion	Remarks. According to the criterion mentioned in the introduction, Janiralata truncata sp. nov. can be assigned into the fourth group based on the presence of plumose setae on the exopod of pleopod III (Wilson & Wägele 1994). Within group D which includes eleven species, the new species mostly resembles three species, J. chuni Thielemann, 1910, J. davisi Menzies, 1951, and J. shiinoi Kussakin, 1962, in lacking posterolateral points and distal concavity (Thielemann 1910; Menzies 1951 b; Wilson & Wägele 1994; Shimomura 2006). However, the former can be easily distinguished from the latter species by the following characteristics: (1) coxal plates of pereonites 2 – 4 are visible dorsally (vs. invisible dorsally); (2) the distal region of the pleotelson is truncated and slightly concave (vs. not truncated and convex); (3) the carpus of pereopod Ⅰ has 14 robust setae (vs. six in J. chuni and eight in J. shiinoi); (4) pleopod Ⅰ has a pair of small rounded projections distally (vs. lacking in J. chuni and J. shiinoi); (5) female pleopod II is concave distally (vs. rounded in J. shiinoi); and (6) the exopod of pleopod III has fewer plumose setae (two plumose setae in the new species vs. five in J. davisi, eleven in J. chuni, and 16 in J. shiinoi) (Thielemann 1910; Menzies 1951 b; Kussakin 1962; Shimomura 2006). Additionally, the new species is similar to J. kurilensis Kussakin, 1962, J. koreaensis, and J. sagamiensis in habitus and morphology of details. However, the new species is easily distinguishable from all the latter species in terms of the Cephalothorax lacking rostrum (vs. having rostrum in J. kurilensis), the distal region of pleotelson (truncated in the new species vs. concave in J. kurilensis vs. rounded in J. koreaensis and J. sagamiensis), and the exopod of pleopod III having plumose setae (vs. lacking plumose setae in the latter species) (Kussakin 1962, 1988; Jang 1991; Shimomura 2006).	en	Kim, Sung Hoon, Kim, Jong Guk, Yoon, Seong Myeong (2022): Description of two new janirid isopods (Isopoda, Asellota, Janiridae) from Korean waters.
