Etymology.

The specific epithet is a Latin word meaning “ arc-shaped ”, referring to the arc-shaped LL; adjective.

Diagnosis.

The female of P. arcuata Zhang, J. Liu & Hu , sp. nov. resembles that of P. allantoides Zhang, Jäger & Liu, 2023 (cf. fig. 2 A – C vs. fig. 8 A – C in Zhang et al. 2023) by having curved anterior and posterior margins of LL, but can be recognised by: 1) S extending horizontally; and 2) FD arising anteriorly from S (vs. S extending longitudinally, FD arising medially from S in P. allantoides ).

Female: Measurements: Small-sized. Body length 6.0, DS length 3.0, width 2.8; OS length 2.9, width 2.0. Eyes: AME 0.13, ALE 0.19, PME 0.22, PLE 0.23, AME – AME 0.11, AME – ALE 0.07, PME – PME 0.21, PME – PLE 0.28, AME – PME 0.19, ALE – PLE 0.26, CH AME 0.23, CH ALE 0.19. Spination: Pp 131, 101, 2121, 1014; Fe I – III 323, IV 321; Pa I – IV 000; Ti I – II 2221, III – IV 2126; Mt I – II 2024, III – IV 2026. Measurements of palp and legs: Pp 3.4 (1.1, 0.8, 0.4, –, 1.1), I 9.3 (2.5, 1.1, 2.6, 2.2, 0.9), II 12.1 (3.2, 1.4, 3.6, 2.8, 1.1), III 7.3 (2.0, 0.7, 2.1, 1.7, 0.8), IV 9.2 (2.9, 0.9, 2.2, 2.3, 0.9). Leg formula: II-I-IV-III. Promargin of chelicerae with three teeth, retromargin with four teeth, cheliceral furrow with c. 28 denticles.

Epigyne (Fig. 2 A – C ): As in diagnosis. EF 2 times wider than long, without obvious AB. Anterior and posterior margins of LL almost parallel and strongly curved. FW covering the whole S. S with enlarged terminal. FD narrow and long, laterad.

Colouration (Fig. 3 A, B ): DS yellow, with black marks. Fovea black. Legs with black spots. Dorsal OS brown, with black spots, ventral OS dark yellow, with several black spots, with a brown patch in front of spinnerets.

Male: Unknown.
