Larval description. – Carapace ( Figs. 21a, d View Fig ): dorsal spine long and curved distally; rostral spine shorter than dorsal spine, approximately equal in length to protopod of antenna, distally spinulate; lateral spines present and straight; 1 pair of posterodorsal setae; ventral margin without setae; eyes sessile.

Antennule ( Fig. 21b View Fig ): uniramous, endopod absent; exopod unsegmented with 2 broad, long, 2 shorter, slender terminal aesthetascs and 1 terminal seta.

Antenna ( Fig. 21c View Fig ): protopodal process distally multispinulate, approximately equal in length to rostral spine; endopod spine present; exopod small, ca. 7% length of protopod with 1 terminal setae.

Mandible: endopod palp absent.

Maxillule ( Fig. 22a View Fig ): epipod seta absent; coxal endite with 7 setae; basial endite with 5 setal processes and 2 small teeth; endopod 2-segmented, proximal segment with 1 seta; distal segment with 6 (2 subterminal, 4 terminal) setae; exopod seta absent.

Maxilla ( Fig. 22b View Fig ): coxal endite bilobed with 4+4 setae; basial endite bilobed with 5+4 setae; endopod bilobed, with 3+5 (2 subterminal, 3 terminal) setae; exopod (scaphognathite) margin with 4 setae and 1 long distal stout process.

First maxilliped ( Fig. 23a View Fig ): coxal segment with 1 seta; basis with 10 setae arranged 2,2,3,3; endopod 5-segmented with 3,2,1,2,5 (1 subterminal, 4 terminal) setae respectively; exopod 2-segmented, distal segment with 4 long terminal plumose natatory setae.

Second maxilliped ( Fig. 23b View Fig ): coxa without setae; basis with 4 setae arranged 1,1,1,1; endopod 3-segmented, with 1,1,5 (2 subterminal, 3 terminal) setae respectively; exopod 2-

segmented, distal segment with 4 long terminal plumose natatory setae.

Third maxilliped: absent.

Pereiopods: absent.

Abdomen ( Figs. 24a, b View Fig ): 5 somites; somite 2 with 1 pair of dorsolateral processes directed anteriorly; somite 3 with 1 pair of dorsolateral processes directed ventrally; somites 1- 2 with rounded posterolateral processes and 3-5 with long posterolateral spinous processes; somite 1 without setae; somites 2-5 with 1 pair of posterodorsal setae; pleopod buds absent.

Telson ( Figs. 22c View Fig , 24a, b View Fig ): each fork long, gradually curved distally; 1 large and 1 smaller lateral spine; 1 large dorsal medial spine; posterior margin with 3 pairs of stout spinulate setae.
