Persephona mediterranea (Herbst, 1794)

First zoea. Carapace ( Fig. 2 A): Globose, small plumose setae present near base of dorsal spine. Dorsal, rostral and pair of lateral spines present. Eyes sessile.

Antennule ( Fig. 4 A): Uniramous, unsegmented, conical, 3 aesthetascs + 1 simple seta terminally.

Antenna ( Fig. 4 A): Present as small bud, about one-third as large as antennule.

Maxillule ( Figure 6 A): Coxal endite, 5 plumose setae. Basial endite, 3 plumose setae + 1 plumodenticulate seta and 1 simple seta may also be present. Endopod unsegmented, 4 simple setae terminally.

Maxilla ( Figure 7 A): Coxal endite bilobed, 2 + 3 plumose setae and microtrichia. Basial endite bilobed, 8 plumose setae (4 + 4) and microtrichia. Endopod, 4 plumose setae (2 + 2) and microtrichia. Scaphognathite, 4 marginal plumose setae, posterior part with strong apical process bearing many microtrichia.

First maxilliped ( Fig. 8 A): Coxa, without setae. Basis, 8 medial plumose setae (2 + 2 + 2 + 2) on the ventral side. Endopodite 5 -segmented, 2 + 2 +0+ 2 + 5 (one subterminal and four terminal) setae. Exopod 2 -segmented, 4 long plumose natatory setae terminally.

Second maxilliped ( Figure 9 A): Coxa without setae. Basis, 4 medial setae (1 + 1 + 1 + 1) on inner side. Endopod unsegmented, 3 setae. Exopod 2 -segmented, 4 long plumose natatory setae terminally.

Abdomen ( Fig. 3 A): 5 -segmented, pair of lateral knobs on posterior margin of second abdominal segment, and second pair in middle portion of third segment. Telson wider than long, convex lateral margins with small terminal spine. Posterior margin slightly concave, 3 pairs of plumose setae in central region.
