Bioacoustics of Anansus aowin

Male ( holotype ). Total length 1.04, carapace width 0.48. Leg 1: 3.87 (0.97 + 0.20 + 0.97 + 1.20 + 0.53), tibia 2: 0.67, tibia 3: 0.50, tibia 4: 0.77. Tibia 1 L/d: 17. Habitus as in Figs. 4, 5 ; carapace brown, mottled with black, sternum with distinctive pattern of four black lines on each side (cf. Fig. 8 ), legs light brown to ochreyellow, abdomen gray with distinct black line dorsally reaching the spinnerets ( Fig. 4 ); distance PME–PME 25 µm; diameter PME ~80 µm (slightly oval shape); distance PME–ALE 15 µm; AME missing. Sternum wider than long (0.38/0.30), unmodified. Clypeus with tiny median projection on ventral rim ( Fig. 43 ); chelicerae with pair of simple frontal apophyses (Figs. 34, 44), with proximo-lateral apophyses directed backwards ( Fig. 46 ), without stridulatory ridges. Palps as in Figs. 32, 33; coxa unmodified, trochanter with distinct ventral apophysis, femur small, with prominent ventral and small prolateral projections, tibia very large, procursus ( Figs. 37 , 45 ) consisting of proximal part with ventral pointed projection and distinctive sclerite set with brush of hairs, and large distal part, the latter complex and hinged towards proximal part; bulb simple, consisting of globular part and weakly sclerotized curved embolus ( Fig. 47 ); palpal tarsal organ capsulate. Legs without spines and curved hairs, few vertical hairs; retrolateral trichobothrium of tibia 1 at 25%, prolateral trichobothrium apparently absent on tibia 1, present on other legs; tarsus 1 with about 12 pseudosegments, only distally fairly distinct; tarsus 4 with complex comb-hairs ventrally ( Figs. 50, 51 ). Male gonopore with four epiandrous spigots ( Fig. 48 ). ALS with one widened, one pointed, and five cylindrically shaped spigots ( Fig. 49 ). Variation. Tibia 1 in other males: 1.03, 1.07. No other variation seen. Female. In general similar to male but clypeus unmodified. Tibia 1: 0.87 (missing in other female). Epigynum a simple dark frontal plate with pair of small pockets close together near posterior rim, and narrow posterior plate (Fig. 35; externally similar to A. ewe , cf. Fig. 9 ); internally with conspicuous dark structures of unknown significance and pair of small pore plates (Fig. 36).
