Fig. 5. Neocyclops (Protoneocyclops) mediterraneus (Kiefer, 1960), adult male. A, body, dorsal; B, detail of rostral plate; C, genital somite, ventral; D, 

 anal somite and caudal rami, dorsal; E, antennule; F, fifth leg. 



Geniculations between segments homologous with ancestral seg- 

 ments XV and XVI (10 and 1 1), and between XX and XXI (14 and 

 15). Segment 10 cup-shaped, forming sheath around proximal half 

 of segment 1 1 . Segmental fusion pattern and armature as follows: 

 segment 1 (corresponding to fused ancestral segments I to V), 8 setae 

 + 3 aesthetascs; segment 2 (partially fused ancestral segments VI and 

 VII), 4 setae; segment 3 (VIII), 2 setae; segment 4 (IX), 2 setae + 



aesthetasc; segments 5 to 8 (X to XIII), 2 setae each; segment 9 

 (XIV), 2 setae + aesthetasc; segments 10 and 11 (XV and XVI), 2 

 setae each; segment 12 (XVII), 2 setose spines; segment 13 (XVIII), 

 1 setose spine, 1 seta + aesthetasc; segment 14 (fused segments XIX 

 and XX), 1 modified flattened spine and 3 setae; segment 15 

 (partially fused segments XXI and XXII), 2 modified flattened 

 spines, 1 seta + aesthetasc; segment 16 (fused segments XXIII to
