description: Dugastella valentina
Zoea I
Duration of stage: 1–2 days
Size: tl= 2.45 ± 0.05 mm; cl = 0.80 ± 0.02 mm; cw= 0.69 ± 0.05 mm.
Carapace (Figs. 1A, D). Rostrum triangular, very short, acute straight and directed somewhat downwards. Eyes large and sessile.
Antennule (Fig. 2A). Peduncle 3-segmented with a long plumose seta on distal segment. Endopod absent. Exopod unsegmented, broad, with 3 terminal aesthetacs and 2 setae.
Antenna (Fig. 2D). Protopod unsegmented. Endopod long 5-segmented and without setae. Exopod with 11 plumose setae on distal margin.
Mandible (Fig. 3A). Molar process with 6–8 marginal teeth, lacinia mobilis as 1 curved spine. Incisor process with 3 small teeth.
Maxillule (Fig. 3D). Coxal endite with 5 spines (processes). Basal endite with 3 subterminal, and 5–6 terminal spines (processes). Endopod with 2 terminal and 1 subterminal setae.
Maxilla (Fig. 3G). Coxal endite bilobed, proximal lobe with 10–11 setae, distal lobe with 1 terminal and 2 subterminal plumose setae. Basal endite bilobed, both with 1 terminal and 1 subterminal setae. Endopod with 1 terminal and 1 subterminal setae. Exopod (scaphognatite) with 10 plumose setae on anterior and lateral margin and a long distal stout setose process.
First Maxilliped (Fig. 4A). Biramous. Coxa with 3 setae, 2 simple and 1 plumose. Basis with 4–5 small terminal simple setae. Endopod 4-segmented with 0, 1, 0, 5 setae respectively. Setae plumose on distal segment. The exopod is longer than the endopod with 4 long terminal and 2 short subterminal plumose setae.
Second Maxilliped (Fig. 4D). Biramous. Coxa with 2 simple setae. Basis with 2 sparsely setose setae. Endopod 5-segmented longer that the exopod, isquium and merus both with 1 simple seta, carpus without setae, propodus with 2 distal simple setae and dactylus with a long spinulated and serrate seta, and 1 subterminal and 2 terminal setae. Exopod with 4 long terminal and 2 short subterminal plumose setae.
Third Maxilliped (Fig. 4G). Biramous. Coxa with a elongated bud (epipodite). Basis with 1 simple seta. Endopod 5-segmented longer that the exopod, isquium with 1 simple seta, merus and carpus without setae, propodus with 2 distal simple setae and dactylus with a long spinulated and serrate seta, and 1 subterminal and 2 terminal setae. Exopod with 4 long terminal and 2 short subterminal plumose setae.
Pereiopods (Figs. 5A–E). Uniramous, well developed. Cheliped and second pereiopod slightly segmented and pereiopods third to fifth clearly segmented. Elongated buds (epipodite) on coxa. Terminal segment of cheliped and second pereiopod slightly quelated.
Abdomen (Figs. 1A, D). Six-segmented, distal segment fused with telson.
Pleopods (Fig. 6D). Biramous. On abdominal segments 1 to 5; exopod and endopod as well developed buds.
Telson (Fig.6A). Diverging posteriorly, indented at median line on posterior margin. Bearing 2 pair of simple setae on lateral margin, 7+7 plumose setae on posterolateral and posterior margin (2 innermost pair smaller), and 2 pair of simple setae on postero-dorsal margin.
