Antennule ( Fig. 4 View FIGURE 4 C): Uniramous, unsegmented, conical, 2 aesthetascs + 1 simple seta terminally. Aesthetascs similar in size, approximately 1.5 times size of antennule.

Antenna ( Fig. 4 View FIGURE 4 C): Present as small bud, about 1/4 size of antennule.

Maxillule ( Fig. 6 View FIGURE 6 C): Coxal endite, 7 plumodenticulate setae. Basial endite, 4 plumodenticulate setae; 1 small simple seta may also be present. Endopod unsegmented, 4 plumose setae terminally.

Maxilla ( Fig. 7 View FIGURE 7 C): Coxal endite bilobed, 3+4 plumodenticulate setae and microtrichia. Basial endite bilobed, 8 plumodenticulate setae (4+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 View FIGURE 8 C): Coxa, without setae. Basis, 8 medial simple setae (2+2+2+2) on the ventral side. Endopodite 5-segmented, 2+2+0+2+ 4 setae. Exopod unsegmented, 4 long plumose natatory setae terminally. Second maxilliped ( Fig. 9 View FIGURE 9 C): 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 View FIGURE 3 C): 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; 1 small simple seta may also be present on distal margin of telson.
