Fig. 19. Paramisophria japonica, female. A, Genital double-somite, ventral view; B, Antennary exopod; C, First and second praecoxal 

 endites of maxilla; D, Fourth and fifth endopod segments of maxilliped; E, Sixth endopod segment of maxilliped. Scales in mm. 



lose setae; basal spine (Fig. 20D) naked. Maxilliped with 

 same setal formula as P. japonica. 



Leg 5 (Fig. 20E): coxae and intercoxal sclerite clearly 

 separate; setation and spinulation as in P. japonica; endopod 

 completely fused to basis; exopod almost completely fused to 

 basis with fine suture visible; first and second exopod seg- 

 ments fused with suture clearly visible on posterior surface; 

 second and third exopod segments completely fused. 



Remarks. Re-examination of the holotype and paratype 

 revealed the following: (1) since the antennules of both types 

 are missing (the proximal half remains on one side only), we 

 were unable to check the fusion and armature patterns; (2) 

 the terminal segment of the antennary exopod has only 2 

 developed setae plus 1 minute seta although 3 developed 

 setae were shown in the original description (Campaner, 

 1977); (3) the dorsalmost tooth on the mandibular gnatho- 

 base is bicuspid although it was originally drawn as monocus- 

 pid (Campaner, 1977); (4) the terminal segment of the 

 mandibular exopod has 2 relatively well developed setae (one 

 about 25% shorter than the other); (5) the setae on the 

 mandibular endopod are missing but there are 2 scars visible, 

 of different sizes, which suggests 2 unequal setae; (6) the 

 coxal epipodite of the maxillule of the holotype is damaged: 5 

 long setae are present, then a gap due to damage, then a short 

 seta; although the gap does not show clean scars where setae 

 were broken off, the gap is only big enough for 2 setae - 

 giving a total of 8 setae as in the paratype; (7) the first to sixth 



endopodal segments of the maxilliped bearing 1 , 4, 4, 3, 3 and 

 4 setae, respectively; (8) no seta originating from the poste- 

 rior surface of the first exopodal segment of leg 4.
