Nota : A1 4 distinct segments.Faint line suggesting coalescence on proximal third of segment 3 corresponds to segmentation between segments III and IV of female. 4th segment of male corresponds to segments V, VI and VII of female. A2 subprehensile, 3-segmented. Basal segment unarmed ; 1 seta on short 2nd segment.Distal segment with terminal grouping of 7 setae, 1 three times the length of the remaining 6, 1 of which is plumose. Inner surface of 3rd segment with patches of hairs and 1 small spine near base of long seta ; 2 setae on outer margin. Md and Mx1 reduced to vestiges, represented only by the bases ; each with undefined margins. Mx2 with 2 terminal spines, 1 nude and 1 wiyh unilateral row of hairs ; 1 seta on lateral margin. Slightly sinuate spine, with unilateral patches of hairs, on small lobe protruding subapically. Mxp 3-segmented ; 2nd segment with spine and graduated row of coarse spinules on medial margin, followed by row of rugose striations. P6 probably represented by small triangular sclerotized ridge on ventrolateral posterior margin of genital segment, bearing 1 setule.
