Bioacoustics of Nanometa forsteri

DESCRIPTION: Female total length 3.3. Cephalothorax length 1.1, width 1.0. Clypeus height 1.0 AME diameter. Cephalothorax background pale yellow, light-gray coloration concentrated over the ocular area and the carapace lateral edges (fig. 36A). Endites and sternum color dark brown (fig. 36C). Cheliceral promargin and retromargin with three and two teeth respectively, cheliceral denticles present ca. 2. Abdomen dorsum background light gray, silvery guanine patches covering all abdomen dorsal surface, except the central line (fig. 36A), lateral surface covered with guanine patches over its dorsal half, ventral half with brown pattern (fig. 36E), ventral surface with a central brown rectangle, flanked by a line of silvery guanine patches (fig. 36C). Booklung stridulatory organ absent. Femur I length 1.8. FD FIGURE 35. Nanometa forsteri . (GH1139). A. Pedipalp, ventral. B. Pedipalp, ectal. C. Pedipalp, dorsal. D. Epigynum, ventral. E. Epigynum, dorsal. Scale bars: A–D, 0.2 mm ; E, 0.1 mm . Trachea, spinnerets not observed with SEM. Internal genital structures not observed. Epigynum typical of the genus (figs. 35D, E, 36B). Description based on specimen (GH1139). Male same as female except as noted. Total length 2.4. Cephalothorax length 1.72 width 1.0. Clypeus 0.6 AME diameter. Cephalothorax and abdomen coloration lighter than in female, silvery guanine patches less conspicuous. Cheliceral promargin and retromargin with three and two teeth respectively, cheliceral denticles present ca. 2. Stridulatory organ formed by a cuticular ridge highly sclerotized on the booklung anterior edge, coxa IV retrolateral not examined with SEM. Femur I length 1.8. CEBP tip with a small tooth (figs. 34D, 35A–C). CEMP square in shape and ca. 1/4 of the cymbium length (figs. 34B, 35C). Conductor distal apophyses surface smooth, tip C-shaped (figs. 34, 35A–C). Description based on specimen (GH1139). VARIATION: Females ( N = 2) total length 3.2– 3.3, cephalothorax length 1.1–1.2, width 0.9–1.0.
