Setal formula 3, 3, 3 + 1 aesthetasc, 3,7+1 aesthetasc. Antenna 5-segmented (Fig. 8A); coxa unarmed; basis with vestigial exopod bearing 2 naked setae, one apically and one halfway along inner margin. Basis armed with 2 inner angle setae. Endopod 3-segmented; setal formula 1,4, 6. Labrum (Fig. 9C) with strong denticles along mid posterior margin. Mandible (Fig. 9A) with well developed gnathobase bearing row of sharp blades medially, and 1 spinulose seta at inner distal angle. Vestigial mandibular palp with 2 long plumose setae and 1 naked seta distally. Inner posterior margin of mandible with two spinular rows. Maxillule with strong praecoxa and reduced 2-segmented palp (Fig. 9B). Praecoxal endite armed with 4 setae articulating at base and 4 spines fused to segment. Proximal segment of palp derived from coxa and basis, bearing 2 naked and 1 spinulose inner margin setae, plus outer seta representing exopod. Distal segment of palp representing endopod, armed with 3 naked setae. Maxilla (Fig. 9D) consisting of praecoxa, coxa, basis and 2-segmented endopod. Praecoxa with single indistinct endite armed with 2 plumose setae. Coxa with inner seta at midlength and distal endite bearing strong plumose seta and naked seta apically. Basis with 3 setae distally. Endopod with 2 setae on proximal segment and 3 setae Please note that these images are extracted from scanned page images that may have been digitally enhanced f
