Bioacoustics of Guaranita munda

Redescription (amendments; see Huber 2000 ) Measurements of male from E of Nono: total body length 1.06, carapace width 0.42; distance PME– PME 40 µm; diameter PME 50 µm; distance PME–ALE 15 µm; distance AME–AME 15 µm; diameter AME 30 µm. Leg 1: 1.98 (0.52 +0.14 +0.50 +0.50 +0.32), tibia 2: 0.42, tibia 3: 0.38, tibia 4: 0.60; tibia 1 L/d: 8; diameters of leg femora 0.09; of leg tibiae: 0.06. Tibia 1 in 25 males (incl. holotype ): 0.49 – 0.58 (mean 0.53). Sternum slightly wider than long (0.33/0.29). Chelicerae as in Fig. 9A – C ; stridulatory files ( Fig. 12A ) with ~15 – 17 ridges each; distances between ridges proximally ~1.0 µm, distally ~2.1 µm. Pedipalp as in Fig. 8A – C ; tibia with two trichobothria; palpal tarsal organ capsulate ( Fig. 13A ) with small opening (diameter of opening 1.15 µm); procursus as in Fig. 9D – F , with large transparent ventral membrane, distinctive dorsal flap, and tip bent towards dorsal; genital bulb as in Fig. 9G – I , with simple proximal sclerite, distal sclerite short and simple, not widened in mid-section. Legs without spines and curved hairs; vertical hairs not seen in dissecting microscope but present on tibia 1 ( Fig. 13D ), apparently only one row; prolateral trichobothrium absent on tibia 1, present on other leg tibiae; metatarsi 3 and 4 with few (3 – 5) slender hairs proximally on retrolateral-ventral side ( Fig. 13E ). Gonopore with 4 – 5 epiandrous spigots ( Fig. 11E – F ); spinnerets as in female (see below). Tibia 1 in 22 females : 0.48 – 0.58 (mean 0.54). Female chelicerae without stridulatory ridges ( Fig. 12B ). Female internal genitalia with strong median structure and membranous sac (receptacle?) ( Fig. 10C – D ); apparently with small pore plates ( Fig. 32B ). Each ALS ( Fig. 11H ) with one strongly widened spigot, one long pointed spigot, and five cylindrical spigots (of which one is much wider than the others); each PMS with two conical spigots; PLS without spigots. Leg tarsal organs with very small openings (diameters of openings 0.8 – 0.9 µm; Fig. 13B ). Metatarsi 3 and 4 with long slender hairs as in male; tarsus 4 with single prolateral comb-hair as in male.
