Key to Recent genera of Calappidae in 

 the western Atlantic Ocean 



1. Chelae essentially symmetrical, no unusually 

 enlarged teeth or protuberances, Subfamily 



Matutinae 2 



Chelae dissimilar, major chela with large tooth 

 on dactyl and pair of protuberances on pro- 

 podus. Subfamily Calappinae 3 



2. Carapace considerably broader than long, 



regularly convex above 



Hepatus Latreille 1802 



Carapace nearly as long as broad, dorsal 

 surface uneven Osachila Stimpson 1871 



3. Posterolateral region of carapace not ex- 

 panded into dentate, winglike projection. . . .4 

 Posterolateral region of carapace expanded 

 into dentate, winglike projection 5 



4. Merus of cheliped bispinous on distal outer 

 surface, with lower spine strong and greatly 



extended laterally 



Acanthocarpus Stimpson 1871 



Merus of cheliped not bispinous on distal outer 

 surface, carapace subcircular, small spine at 

 lateral angle Cycloes De Haan 1837

Pereopod 5 with row of spines on flexor sur- 

 face of ischium-merus

6. Greatest span of winglike posterolateral pro- 

 jections less than maximal span between 

 anterolateral margins; outer proximolateral 

 corner of palm bearing short, flattened, 



smoothly crested ridge 



Cyclozodion new genus 



Greatest span of winglike posterolateral pro- 

 jections exceeding maximal span between 

 anterolateral margins; outer proximolateral 

 corner of palm bearing flattened acute spine
