Bioacoustics of Nanometa sarasini

DESCRIPTION: Female (TEAU011) total length 8.9. Cephalothorax length 3.6, width 2.7. Clypeus height 1.1 AME diameter. Cephalothorax background dark yellow, cephalic region and carapace margins dark brown (fig. 14A, C). Eyes subequal in size, lateral smaller. Sternum dark brown (fig. 14E). Cheliceral promargin and retromargin each with three teeth, ca. three cheliceral denticles. Abdomen dorsum background gray, ca. six to five pairs of guanine patches concentrated in the center and delineated by dark-brown patches (fig. 14A). Stridulatory organ present in females as a cuticular thick and highly sclerotized ridge on booklung anterior edge (fig. 14H). Lateral line of guanine patches diffuse and intercalated with dark-brown reticulated spots (fig. 14C). Femur I length 6.9. Copulatory ducts modified as membranous sacs with translucent cuticle and internal sclerotized apodemes, spermathecae longer than wide (figs. 14F, 16E), accessory duct glands not examined with SEM. Male (TEAU012) same as female except as noted. Total length 6.9. Cephalothorax length 3.1, width 2.5. Clypeus 2.0 AME diameter (fig. 14I). Cephalothorax and abdomen lighter than in female. Cheliceral promargin and retromargin with three and one teeth respectively, denticles ca. 10. Stridulatory organ slightly longer, coxa IV retrolateral not examined with SEM. Femur I length 7.5. Conductor tip apophyses present (figs. 15A, F, H, I, 16A–C). FD FIGURE 16. Nanometa sarasini (QM S25460 ). A. Pedipalp, ventral. B. Pedipalp, dorsal. C. Pedipalp, ectal. D. Epigynum, ventral. E.
