Material examined. Zoea I (Fig. 1; Fig. 3A; table 1) from RA (N = 20) (catalogue number 15723): Carapace length (CL) = 0.71 ± 0.05 mm; Carapace width (CW) = 0.61 ± 0.03 mm; Rostro-dorsal Length (RDL) =1.4 ± 0.06 mm and, FN (N= 20): CL = 0.73 ± 0.05 mm; CW = 0.58 ± 0.05 mm; RDL =1.5 ± 0.09).
Table modified from Cuesta et al. 2007, * include distance between tips of lateral spines
Carapace (Fig. 1; 3A): Globose, ventral and posterior margin smooth, with a pair of posterodorsal simple seta. Dorsal, rostral and lateral spines present, dorsal spine longer than rostral spine, lateral spines well developed and deflected ventrally. Sessile eyes.
Antennule (Fig. 2A; 3B. 1): Primary flagellum unsegmented with 2 long and 2 shorter and thinner terminal aesthetascs, and 1 simple shorter seta; accessory flagellum absent.
Antenna (Fig. 2B; 3B. 2): Biflagellate; protopod with 2 rows of well-developed spinules. Endopod absent. Exopod half the length of the protopod, with 1 long and 1shorter terminal setae, and 4 minute terminal spines).
Mandibles: Endopod palp absent.
Maxillule (Fig. 2C; 3C): Coxal endite with 6 plumose setae. Basial endite with 5 plumose setae, and 1 distal tooth. Endopod 2-segmented, proximal segment with 1 seta, distal segment with 5 setae (2 terminal, 2 subterminal and lateral bud with apical long seta).
Maxilla (Fig. 2D; 3D): Coxal endite bilobed with 5 + 4 setae; microtrichia on lateral margins. Basial endite bilobed, with 5 + 4 setae; microtrichia on lateral margins. Endopod unsegmented with 2 terminal and 2 subterminal setae; microtrichia on lateral margins exopod (scaphognathite) with 4 plumose setae; margins of terminal process with microtrichia on distal half.
First maxilliped (Fig. 2E; 3E): Coxa with 1 setae. Basis with 10 setae arranged 2+2+3+3. Endopod 5-segmented with 2, 2, 1, 2, 5 (2 terminal, 2 subterminal and 1 lateral setae). Exopod unsegmented, with 4 terminal plumo-natatory setae.
Second maxilliped (Fig. 2F; 3F): Coxa without setae. Basis with 4 setae 1+1+1+1. Endopod 3-segmented with setae arranged, 1, 1, 6 (3 subterminal + 3 terminal). Exopod unsegmented, with 4 long plumo-natatory setae.
Third maxilliped: absent.
Pereiopods: absent.
Pleon (Fig. 2G; 3 G, H, I): Five pleonites. Pleonites 2-3 with a pair of dorsolateral process. Pleonites 2-5 with a pair of posterolateral setae (Fig. 3 I). A single mid-dorsal seta on first pleonite (Fig. 3 H): Pleopods absent
Telson (Fig. 2H; 3J): Bifurcated, posterior margin with 3 pairs of serrulate setae. A minute dorsal spine basally on each furcal arm (detail of Fig. 2H; 3K).
