Mothocya bohlkeorum Williams and Williams, 1982 

 Figure 84B 



DIAGNOSIS Ovigcrous 9 7.6-8.5 mm, d 3.7 mm. Cephalon anteriorly nar- 

 rowed in dorsal view, ventrally flexed, broadly rounded; slighdy immersed in 

 pereonite 1. Pleotelson subrectangular. Uropods extending slightly beyond 

 posterior margin of pleotelson; exopod only slightly longer than endopod. $ 

 lateral lobes of pleopodal peduncles not developed. Endopods of pleopods 3- 

 5 with small proximomedial lobe. 



RECORDS Whitestar cardinalfish Apogon lachneri: Puerto Rico. Dusky car- 

 dinalfish Phaeoptyx pigmentaria: Bahamas. Freckled cardinalfish Phaeoptyx con- 

 klini: Florida Keys; Bahamas. Conchfish Astrapogon stellatus: Leeward 

 Islands. 



Mothocya nana (Schioedte and Meinert, 1884) 

 Figure 84A 



DIAGNOSIS Ovigerous $ 11.0-17.0 mm, 6 7.9-8.3 mm. Cephalon deeply 

 immersed in pereonite 1; rostrum anteroventrally narrowly rounded. Uropo- 

 dal exopod markedly longer than endopod. Pleotelson broad, with posterior 

 margin rounded sufficiently to give appearance of being subtriangular. 



RECORDS Halfbeak Hyporhamphus unifasciatus : Chesapeake Bay, Maryland; 

 Georgia; Florida; Colon, Panama. Halfbeak Hemiramphus bermudensis: 

 Bermuda. 



Nerocila Leach, 1818 



DIAGNOSIS Body generally more depressed than in most cymothoid genera, 

 rarely curved. Cephalon with anterior margin convex, narrowly rounded, or 

 concave; not, or only slightly, immersed in pereonite 1. Pereonite 1 anterior 

 margin Insinuate. Posterolateral angles of pereonites weakly to strongly pro- 

 duced, increasing in length posteriorly. Coxal plates prominent, usually al- 

 most reaching or extending to posterior margin of their respective pereonites. 

 Juveniles and 6 usually with spines on posterior pereopods; 9 lacking these 

 spines. Pleon not immersed in pereonite 7. Pleonites subequal in length; 

 pleonites 1 and 2 usually produced posterolaterally. Pleopods typically with 

 small lamellar accessory gills; pleopods 3-5 folded into deep pockets or 

 pleats. Uropods usually extending beyond pleotelsonic apex.
