Leptodius sanguineus (H. Milne Edwards, 1834)

(Figs. 28–30)

Zoea I. Size (mean ± sd): CW = 0.68 ± 0.01 mm; CL = 0.56 ± 0.03 mm; TT = 1.4 ± 0.03.

Cephalothorax (Figs. 28a). Dorsal spine long, spinulated, straight, curved distally; rostral spine straight, equal in length of protopod of antenna, shorter than dorsal spine; lateral spines straight; one pair of posterodorsal setae; eyes sessile.

Antennule (Fig. 28b). Uniramous, endopod absent; exopod unsegmented with 4 broad aesthetascs, one terminal seta.

Antenna (Fig 28c). Protopodal process distally multispinulate, equal in length of rostral spine; endopod bud present; exopod small, robust, 13% length of protopod with one terminal seta.

Maxillule (Fig. 29a). Coxal endite with 7 plumodenticulate setae; basial endite with 5 (3 cuspidate, 2 plumodenticulate) setae; endopod 2-segmented, proximal segment with one simple seta, distal segment with 2+4 setae; exopod setae absent.

Maxilla (Fig. 29b). Coxal endite bilobed with 4+4 plumodenticulate setae; basial endite with 5+4 setae; endopod unsegmented, bilobed with 3+5 plumodenticulate setae; exopod (scaphognathite) margin with 4 plumose setae; one stout distal process.

First maxilliped (Fig. 29c). Basial endite with 10 medial simple setae arranged 2+2+3+3; endopod 5-segmented with 3,2,1,2,5 setae respectively; exopod 2-segmented, distal segment with 4 terminal plumose natatory setae.

Second maxilliped (Fig. 29d). Basial endite with 4 medial simple setae arranged 1+1+1+1; endopod 3-segmented with 1,1,2+3setae. Exopod 2-segmented, distal segment with 4 terminal plumose natatory setae.

Pleon (Fig. 30a). Five somites; somite 2 with one pair of dorsolateral processes directed anteriorly; somite 3 with one pair of dorsolateral processes directed posteriorly; somites 1 and 2 with rounded posterolateral process; somites 3–5 with short posterolateral spinous processes; somite 1 without setae; somites 2–5 each with one pair of posterodorsal setae.

Telson (Fig. 30b). Each fork gradually curved distally with 2 lateral and 1 medial spines; inner margin with 3 pairs of stout spinulate setae.
