Bioacoustics of Nanometa dimitrovi

DESCRIPTION: Female ( S27683 ; SEM observations from Álvarez-Padilla and Hormiga, 2011 : specimen code SEM-FAP048 from the paratype series S27687 ) total length 2.3. Cephalothorax length 0.9, width 0.7. Clypeus height 1.0 AME diameter. Cephalothorax background pale yellow light gray concentrated over the ocular area and the carapace lateral edges (fig. 36I). Endites and sternum dark gray. Cheliceral promargin and retromargin each with three teeth, cheliceral denticles present ca. 3. Abdomen dorsum background light gray, silvery guanine patches covering all abdomen dorsal surface, except the central line that extends over only half the abdomen length, lateral surface covered with guanine patches over dorsal half, ventral half with darkgray pattern, ventral surface dark gray with a central rectangle flanked by two lines of silvery guanine patches. Booklung stridulatory organ absent. Tracheae and epigynum observed with SEM, median tracheal trunks branched; lateral tracheae tubular (fig. 30D). ALS with one major ampullate, one nubbin, ca. 16 piriform, few tartipores present. PMS with one minor ampullate, one nubbin, and one cylindrical and two central aciniform. PLS with araneoid triplet spigots clustered together, ca. five aciniform distributed in one row between the two peripheral cylindrical gland spigots. The anterior cylindrical spigot is considerably thicker than the other. Femur I length 1.24. Copulatory ducts modified as membranous sacs with smooth cuticle, spermathecae round, accessory duct glands clustered on puffball-shaped clusters (figs. 30B, 32E). Male same as female except as noted. Total length 2.3. Cephalothorax length 1.0 width 0.8. Clypeus 1.1 AME diameter (fig. 36J). Cephalothorax and abdomen coloration slightly darker than in female, silvery guanine patches less conspicuous. Cheliceral promargin and retromargin with three and two teeth respectively, cheliceral denticles present ca. three. Stridulatory organ formed by a cuticular ridge on the booklung anterior edge, coxa IV retrolateral surface covered with small teeth opposite to the booklung ridge (fig. 30C). Femur I length 1.6. Pedipalp with small paracymbium and spikelike CEBP (figs. 30F, 31B, D). Conductor tip with one distal blunt apophysis and cuticle covered with scales (figs. 30E, GH, 31F, H). VARIATION: Females ( N = 3) total length 2.3– 2.6, cephalothorax length 0.9–1.0, width 0.7–0.8. The epigynum septum and the epigynal plate vary on their width.
