Bioacoustics of Nanometa lagenifera

DESCRIPTION: Female (TEAU009, TEAU024, TEAU040) total length 8.0. Cephalothorax length 3.0, width 2.4. Clypeus height 1.1 AME diameter. Cephalothorax yellow with darkbrown pattern (fig. 20A, C). Eyes subequal in size, lateral smaller (fig. 20G). Sternum dark brown (fig. 20E). Cheliceral promargin and retromargin with three and two teeth, respectively, ca. five cheliceral denticles. Abdomen dorsum background gray, guanine patches concentrated in the center, delineated by two lines of dark-brown chevrons and guanine patches (fig. 20A). Lateral line of guanine patches diffuse and intercalated with dark-brown reticulated spots (fig. 20C). Tracheae observed with SEM, median tracheael trunks branched, lateral tracheae tube shaped. Femur I length 5.9. Copulatory ducts modified as membranous sacs with translucent cuticle and internal sclerotized apodemes, spermathecae oval, translucent, and weakly sclerotized (figs. 20H, 24E), accessory duct glands clustered on puDzallshaped clusters (figs. 23D, 24E). Male (TEAU010) as female except as noted. Total length 7.5. Cephalothorax length 2.1, width 2.4. Clypeus 1.2 AME diameter (fig. 20I). Cephalothorax and abdomen lighter than in female. Cheliceral promargin and retromargin with three and two teeth respectively, denticles ca. two. Stridulatory organ formed by a cuticular thick and highly sclerotized ridge on the booklung anterior edge, coxa IV retrolateral not examined with SEM. Femur I length 10.2. Basal apophysis of conductor tip absent, distal apophysis short and heavily sclerotized (figs. 22B, F, 24A–C). VARIATION: Females ( N = 3) total length 7.0– 8.0, cephalothorax length 2.8–3.0, width 2.1–2.4. Males ( N = 2) total length 7.4–8.0, cephalothorax length 2.1–3.3, width 2.4–2.5.
