Bioacoustics of Aetana manansalai

Description Male ( holotype ) MEASUREMENTS. Total body length 3.2, carapace width 1.3. Leg 1: 36.5 (8.5 + 0.5 + 8.5 + 15.5 + 3.5), tibia 2: 5.2, tibia 3: 3.5, tibia 4: 5.3; tibia 1 L/d: 67. Distance PME-PME 350 µm , diameter PME 125× 150 µm , distance PME-ALE ~ 45 µm ; AME absent. COLOR. Carapace ochre-yellow with narrow lateral marginal bands and wide dark brown median band including posterior part of ocular area; clypeus ochre yellow with indistinct light brown pattern; sternum light brown to orange, laterally paler, labium darker; legs greenish ochre with slightly darker rings on femora (subdistally, with light tip), and tibiae (proximally and subdistally, the latter followed by light tip); abdomen ochre-gray, dorsally and laterally covered with many black marks, ventrally with dark mark behind gonopore and larger less distinct mark in front of spinnerets. BODY. Habitus as in Fig. 182 ; ocular area raised, each triad on additional short hump directed toward lateral, with small process below ALE ( Fig. 221 ); carapace with very shallow median furrow in anterior part only; clypeus medially slightly projecting, with distinctive lateral plates bordered by sclerotized ridges ( Fig. 221 ); sternum wider than long (0.85/0.60), unmodified. CHELICERAE. As in Fig. 221 , with pair of lateral processes proximally and pair of very long lateral apophyses; without modified hairs; without stridulatory ridges. PALPS. As in Figs 219–220 ; coxa unmodified; trochanter with ventral apophysis; femur with small ventro-distal apophysis and retrolateral ridge ending in small hump; patella triangular in lateral view; tibia with retrolateral trichobothrium in very distal position; proximal part of procursus with simple retrolatero-ventral process, with complex and apparently partly hinged distal elements ( Fig. 229 ); bulb with only one process (weakly sclerotized embolus), distally with several small knobs. LEGS. Without spines; with curved hairs on metatarsi 1–3; few vertical hairs; retrolateral trichobothrium on tibia 1 at 3%; prolateral trichobothrium absent on tibia 1, present on other tibiae; tarsus 1 with ~25 pseudosegments, only distally distinct. Male (variation) Tibia 1 in 5 other males: 8.0–8.8 (mean: 8.3). Abdomen with or without additional white spots in dorsolateral rows. Female In general similar to male but clypeus unmodified and with pair of dark brown bands below ALE; eye triads much closer together (distance PME-PME 150 µm ), without processes at ALE; with indistinct stridulatory apparatus between carapace and abdomen: modified area medially on carapace ( Fig. 188 ) versus barely distinguishable hairless area on abdomen. Tibia 1 in 13 females : 5.8–6.5 (mean: 6.3); dark and light rings on legs often more distinct than in males. Epigynum long, anterior half of plate wider and more heavily sclerotized than posterior half, anterior half with pair of low humps ( Figs 222 , 234 ); area behind epigynum with pair of very indistinct membranous pockets in weakly modified cuticle (weak transversal ridges). Internal genitalia as in Figs 223 and 236 , without sclerotized pockets.
