Pseudopoda trinacriformis Zhang, Jäger & Liu , spec. nov. Figs 248–250 View FIGURE 248 View FIGURE 249 View FIGURE 250 , Map 4 View MAP 4

Type material. CHINA, Yunnan Province: Holotype male from Baoshan City, Tengchong County, Langya Mountain , 25.49°N, 98.27°E, 2023 m, 11 June 2014, X. Cao & Y. Zhong leg. ( CBEE, LJ1662 ) GoogleMaps . Paratypes: 1 male, 1 female, with same data as for holotype ( CBEE, LJ1663 – LJ1664 ) GoogleMaps .

Etymology. The specific name is derived from the Latin adjective trinacriformis , - is, - e, meaning “with three apices”, referring to the RTA with three tips in retrolateral view; adjective.

Diagnosis. The male of P. trinacriformis Zhang, Jäger & Liu , spec. nov. resembles that of P. signata by: 1) E longer, almost S-shaped; 2) T with proximal bulge, but it can be recognised by the following combination of characters: 1) E arising from T at 8:00 o’clock position; 2) dRTA broad, distal tip with humps (arising from T at 7:00–7:30 o’clock position, RTA distinct ventral hump in retrolateral view and with two short apices in P. signata ). The female of P. trinacriformis Zhang, Jäger & Liu , spec. nov. is similar to that of P. virgata by the oval shaped EF and the similarly short and situated AB as well as the similarly V-shaped anterior margins of LL, but can be recognised by sclerotised IDS short, with distinct Uturn in ventral view and closer to anterior margins of LL (almost straight, extending laterally beyond FW in P. virgata ).

MALE (LJ1662): Measurements: Small sized. Body length 9.5, DS length 4.5, width 4.0, OS length 5.0,

width 3.2. Eyes: AME 0.18, ALE 0.26, PME 0.24, PLE 0.28, AME–AME 0.12, AME–ALE 0.07, PME–PME 0.24, PME–PLE 0.25, AME–PME 0.27, ALE–PLE 0.22, CH AME 0.33, CH ALE 0.25.

Measurements of palps and legs: Pp 5.8 (1.6, 0.9, 1.2, –, 2.1); I 21.5 (6.2, 2.1, 6.0, 5.6, 1.6); II 24.2 (6.7, 2.2, 6.8, 6.6, 1.9); III 19.7 (5.7, 1.9, 5.3, 5.5, 1.3); IV 21.1 (6.4, 1.3, 5.7, 6.0, 1.7). Leg formula: II-I-IV-III. Cheliceral furrow with ca. 25 denticles.

Palp ( Figs 248A–C View FIGURE 248 ): As in diagnosis. T with a blunt disto-prolaterad projection at distal part. Apical part of E bent, subapical part broadened. Spermophor not easily visible on retrolateral T in ventral view. RTA arising proximally on Ti, dorsal margins looking like mountains.

Colouration ( Figs 250A–B View FIGURE 250 ): DS yellowish with two lateral brown bands. Fovea and striae distinctly marked, with small V-shaped mark in front of fovea. Coxae and trochanters dorsally with dark median line, ventrally with pale dots. Spine patches on femora IV fused. Sternum vividly spotted. Dorsal OS yellow, with dark marks at the margins, with unique arrowhead-pattern, with a brown transversal line and dark patch in posterior part. Ventrally OS yellow with several dots and small patch in front of fovea.

FEMALE (LJ1663): Measurements: Small to Medium sized. Body length 9.8–11.4, DS length 4.6, width 3.8, OS length 6.8, width 5.2.

Measurements of palps and legs: Pp 4.6 (1.4, 0.6, 1.1, –, 1.5); I 12.5 (3.6, 1.3, 3.4, 3.1, 1.1); II 15.3 (4.3, 1.5, 4.5, 3.7, 1.3); III 10.9 (3.2, 1.2, 2.9, 2.7, 0.9); IV 12.8 (4.0, 1.0, 3.1, 3.5, 1.2). Leg formula: II-IV-I-III. Cheliceral furrow with ca. 25 denticles.

Epigyne ( Figs 249A–C View FIGURE 249 ): As in diagnosis. EF wider than long, discontinuous at its anterior margin, with short indistinct AB. LL touching each other only slightly at the median line. Sclerotised part of IDS arranged in a circle in ventral view. FW well developed, posteriorly strongly diverging. FD situated medially, apical ends narrow, laterad.

Colouration ( Figs 250C–D View FIGURE 250 ): As in male, generally darker.
