Nota: Left A1 26-segmented; right A1 24-segmented, segments in the midregion slightly modified: segment 13 shortened and segment 14 lengthened on the outer side; segment 14 with a distal transverse row of spinules, segments 15-18 with 2 rows of finer spinules, and segment 19 with 1 row of very small fine spinules; segment 20 elongated, with its probable tripartite origin (segments 20, 21 and 22 of the female fused) indicated by the placment of the inner elements at three levels and by the 3 transverse rows of fine spinules. Geniculation located between segments 20 and 21. P5 with the intercoxal plate not clearly separated from the two small coxae and having 3 transverse rows of small spinules on its posterior surface
