The Cerapus View in CoL Clade

Cerapinae Smith, 1880: 276.

Cerapiinae Budnikova, 1989: 55.

Diagnosis. Antenna 1: slightly more robust than antenna 2. Antenna 2: peduncle elongate, slender. Mandible: palp large, 3-articulate. Gnathopod 1: subchelate in male and female. Gnathopod 2: carpochelate (rarely subchelate) in male, subchelate in female. Peraeopods 3 and 4: basis inflated, glandular; dactylus not styliform. Peraeopods 5 to 7: distal articles reversed so that dactyli are directed posteriorly; dactyli modified with accessory spines (occasionally unmodified). Peraeopod 5: coxa enlarged, broad and long anteriorly with small posterior lobe (usually much larger in female), with or without fringe of long setae; merus short, broad, anterior margin produced to nearly or completely over reach carpus, posterior margin produced into a large setose lobe; carpus short, reniform with posterior lobe covered in minute denticles; propodus inserts into concave margin of carpus. Peraeopods 6 and 7: similar to each other; peraeopod 7 slightly longer than peraeopod 6, both longer than peraeopod 5. Urosomites: free. Pleopods: decreasing in size from pleopod 1 to 3 (occasionally not modified). Pleopods 2 and 3: reduced inner ramus (occasionally pleopod 3 uniramous or absent). Uropod 1: biramous with a corona of spines at distoventral end of peduncle. Uropods 2 and 3: uniramous with reduced or rudimentary ramus. Telson: short, notched to deeply cleft, each lobe with a dorsal field of recurved spines.
