Persephona lichtensteinii Leach, 1817

First zoea. Carapace ( Fig. 2 B): Dorsal, rostral and pair of curved lateral (about half size of rostral) spines present. Eyes sessile.

Antennule ( Fig. 4 B): Uniramous, unsegmented, conical, 3 aesthetascs + 1 simple seta terminally. Aesthetascs variable in size, approximately 2.5, 2 and 1.5 times size of antennules.

Antenna ( Fig. 4 B): Present as small bud, about half size of antennules, 1 small simple seta.

Maxillule ( Fig. 6 B): Coxal endite, 4 plumodenticulate setae, 3 plumose setae. Basial endite, 3 plumodenticulate setae + 1 simple seta; 1 small simple seta may also be present. Endopod unsegmented, 4 plumose setae terminally.

Maxilla ( Fig. 7 B): Coxal endite bilobed, 4 + 4 plumodenticulate setae and microtrichia. Basial endite bilobed, 9 plumodenticulate setae (5 + 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 B): Coxa, without setae. Basis, 8 medial simple setae (2 + 2 + 2 + 2) on 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 ( Fig. 9 B): Coxa without setae. Basis, 4 medial setae (1 + 1 + 1 + 1) on the inner side. Endopod unsegmented, 4 setae. Exopod 2 -segmented, 4 long plumose natatory setae terminally.

Abdomen ( Fig. 3 B): 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, lateral margins convex, with small terminal spine. Posterior margin slightly concave, 3 pairs of plumose setae positioned in central region.
