Bioacoustics of Priscula salmeronica

Redescription Male (ZFMK, Ar 22106) MEASUREMENTS. Total body length 3.5, carapace width 1.7. Distance PME–PME 180 µm ; diameter PME 110 µm ; distance PME–ALE 110 µm ; AME absent. ALE and PLE larger than PME (diameter ALE 210 µm ). Leg 1: 39.4 (9.8 +0.7 +9.6+17.5 + 1.8), tibia 2: 6.6, tibia 3: 4.5, tibia 4: 6.1; tibia 1 L/d: 66. COLOR (in ethanol). Carapace ochre-yellow with dark mark medially and three pairs of radial marks, with pair of whitish marks beside ocular area; ocular area light brown with darker median and lateral bands, clypeus dark brown; sternum brown, with three pairs of small light spots near bases of coxae 2–4; legs ochre-yellow, with darker rings on femora subdistally, on tibiae proximally and subdistally, and on metatarsi proximally; abdomen dorsally and laterally densely covered with black and white spots, ventrally grey with large brown marks in gonopore area and in front of spinnerets. BODY. Habitus as in Fig. 833 . Ocular area distinctly raised, with hump on posterior side. Deep thoracic groove reaching posterior margin. Clypeus strongly protruding but otherwise unmodified. Sternum wider than long (0.95/0.75), unmodified. Abdomen higher than long, dorso-posteriorly pointed. CHELICERAE. With pair of short apophyses near fang joints (cf. González-Sponga 1999 : figs 59–60), without stridulatory ridges, with pair of distinct white areas laterally that are distally bordered by sclerotized rim. PALPS. As in Figs 852–853 ; coxa unmodified, trochanter slightly protruding ventrally, femur long, with distinct retrolateral process proximally, distinctive sclerotized ventral process at ~¾ of length (arrow in Fig. 852 ), and sclerotized protruding ventral rim distally; patella ventrally reduced to strongly sclerotized narrow rim; tibia small relative to femur; procursus ( Figs 854–856 ) with distinctive distal elements: retrolateral ridge with shallow pocket (arrow in Fig. 856 ), distally with ventral flat sclerite and dorsal membranous element; genital bulb ( Figs 858–860 ) with small proximal sclerite connecting to tarsus, strong main apophysis with distinctive subdistal pointed process (arrow in Fig. 858 ), with large whitish area ventrally between strong proximal transversal sclerite and main apophysis. LEGS. Without spines and curved hairs; few short vertical hairs; retrolateral trichobothrium of tibia 1 at 5%; prolateral trichobothrium present on all leg tibiae; tarsi without distinct pseudosegments but rather with many small platelets. Male (variation) Tibia 1 in other newly collected males: 7.3, 8.0, 8.9. In male holotype (according to original description; not checked): 7.3. Female In general similar to male ( Fig. 834 ), also with hump on posterior side of ocular area, also without curved hairs on legs. Some newly collected females with dark pigment in place of AME but never with lenses. Tibia 1 in 11 newly collected females: 4.0–5.4 (mean 4.7). In female paratype measured in original description ( not checked): 4.3. Epigynum ( Fig. 868 ) large dark brown plate, with dark angular line close to anterior border, posterior margin with whitish triangular area; internal large arc visible in uncleared specimens. Without posterior epigynal plate. Internal genitalia relatively small (compared to epigynal plate; Figs 857 , 869–870 ), with pair of dark sclerites posteriorly and median sclerite between pore plates; pore plates semicircular.
