DIAGNOSIS 6 1.6 mm, 9 1.5 mm. Pereopod 1 d, palm of carpus with two 

 strong outer teeth and one short inner tooth; propodus reaching back to 

 proximal half of carpus, tapering distally; dactylus obsolete. Pleopod 1 S , 

 outer distal lobe acute, reaching well beyond inner lobe. Pleotelsonic margins 

 very faintly serrate. Uropod about 0.7 times length of pleotelson.

DIAGNOSIS S 2.3 mm. Very similar to C. algicola. Pereopod 1 S, carpus 

 with two strong basally broad distal teeth; propodus extending back to merus 

 in adult S, widening to broadly rounded distal margin; dactylus minute. 

 Pleopod 1 d, outer distal lobe narrowly acute, reaching well beyond inner 

 rounded lobe. Uropod about 1.5 times pleotelson length.

Family Joeropsidae Nordenstam, 1933 



DIAGNOSIS Cephalon free, with distinct rostrum. Molar process of mand- 

 ible reduced. Maxillipedal palp articles all of similar width. Antenna short, 

 peduncle dilated, flagellum reduced. Pereonites similar, wider than long. 

 Pereopods similar, biunguiculate. Uropods having short squat sympod and 

 very reduced rami; inserted into submedian posterior notches of pleotelson. 



Joeropsis Koehler, 1885 



DIAGNOSIS Dorsolateral eyes present. Antennule, basal article widest and 

 longest, often with transparent distal dentition. Antenna, peduncular articles 

 3-5 somewhat dilated, article 2 often with fringe of transparent scales; 

 flagellum of about six articles, together shorter than peduncle article 5. Per- 

 eonites similar, generally subequal in length and width. Pleotelson of single 

 shield-shaped segment. Uropodal sympod usually with mesiodistal angle 

 acute; rami reduced.
