Female (from 13°23'N, 102°27'W): A, posterior prosome and urosome (lateral, right side); B, genital complex (lateral, right side); C, idem (ventral). Scale bars: 0.1 mm.

Genital complex symmetrical in ventral view ; with a ventral anterior and posterior bump in lateral view. A1 24-segmented. A2 : coxa with 1 seta ; basis with 2 setae ; endopod 2-segmented, proximal segment with 1 seta, distal segment with 7 setae on subterminal lobe ; exopod 7-segmented with 1, 1, 1, 1, 1, 1, 3 setae. Md : gnathobase with 6 well-developed teeth and 1 seta ; basis with 2 setae ; endopod 2-segmented, proximal segment with 2 setae, distal with 9 setae ; exopod with 1, 1, 1, 1, 2 setae. Caudal ramus with 4 large, thick terminal setae, 1 small dorsal seta and 1 small medial ventral seta.
