Bioacoustics of Afroneta flavescens

Description Male ( holotype , UPSZMC 67563) SIZE. Total length 2.70. Cephalothorax 1.35 long, 0.95 wide. Sternum 0.89 long (0.77 without labium), 0.67 wide. Abdomen 1.41 long, 0.78 wide. AME diameter 0.03. Femur I 1.40 long, 1.04 times as long as cephalothorax. COLOUR (preserved specimen). Cephalothorax yellowish. Chelicerae, sternum, pedipalps, legs and abdomen yellowish ( Fig. 6C ). The colour seen in the female ( Fig. 6A ) also most resembles the true body colour of the male. Black rings around eyes, just like the females ( Fig. 6A ). BODY. Cephalothorax with many short setae. Fovea present, elongated, darker brown, faint/shallow ( Fig. 6C ). Ocular area with several short thin setae between eyes. Clypeus with strong setae below AME. Clypeus height 6.3 times AME diameter. Subocular sulci ( SU ) present below AME, long and wide, but not clearly demarcated as in the females ( Fig. 6A ). Sternum shield–shaped with labium fused to sternum and short narrow extension of sternum between coxae IV (merged to carapace at the end). CHELICERAE. With 3 large widely spaced prolateral teeth. Stridulating files not visible on chelicerae. Three small widely spaced retrolateral denticles, positioned between the two first prolateral teeth. LEGS. All femora with two short stout setae dorsally. Leg formula 1243 (legs 1,2 of 4 almost same length). Trichobothrium metatarsus I = 0.59, very hard to see. Tibial spinal formula 2222. PEDIPALP ( Figs 4A–B , 5A–D ). Patella with long strong distal dorsal spine ( Fig. 4A ). Tibia about as long as cymbium, with two retrolateral and one prolateral trichobothrium ( Figs 4A , 5D ). Cymbium with two prolateral macrosetae. Paracymbium curved, with two basal macrosetae ( Fig. 4A ). Tegular mynoglenine process broad triangular, facing distally ( Fig. 4A–B ). Suprategulum almost straight, finger-like ( Fig. 4A ). Radix drop-like with small straight, robust embolus. According to Merrett (2004) , this is also present in Afroneta bamilekei Bosmans, 1988 . Embolic membrane small, only slightly longer than embolus, exceeding the cymbium marginally ( Fig. 4B ). Female (allotype, UPSZMC 67564) SIZE. Total length 3.25. Cephalothorax 1.53 long, 0.99 wide. Sternum 0.86 long (0.79 without labium), 0.66 wide. Abdomen 1.86 long, 1.08 wide. AME diameter 0.04. Femur I 1.48, long, 0.97 times as long as cephalothorax. COLOUR (preserved specimen, Fig. 6B ). As male holotype . The difference in colour in Figures 6B and C is a technical relict from the different backgrounds. The yellow in Fig. 6A is closest to the real body colour. BODY. Sternum shield–shaped, like male. Clypeus height 5.75 times AME diameter. CHELICERAE. Cheliceral teeth ( Fig. 6A ) and stridulation file as in male. Spination of legs as in male. Leg formula 1243. Trichobothrium metatarsus I = 0.53, very hard to see. EPIGYNUM. The females have a round, centrally separated receptaculum ( Figs 4C , 5G–H ). The dorsal plate scape is well developed ( Fig. 5E–F ). The copulatory duct is very short facing laterally directly from the copulatory opening to the receptaculum and lacking an anteriorly facing copulatory duct ( Figs 4C–D , 5G–H ).
