Diagnosis.

The females of this species resemble that of Massuria min sp. nov. (Fig. 5A, C, D View Figure 5 ) in having a triangular median plate, but differs from it by the carapace lacking dots (vs. present), the slightly parallel copulatory ducts (vs. W-shaped) and the C-shaped spermathecae (vs. fan-shaped) (Fig. 1A, C, D View Figure 1 ). Male can be easily distinguished from other Massuria species ( Xu et al. 2008; Tang and Li 2010b; Lin et al. 2023) by the legs I and II lacking annulations (vs. present), the retrolateral tibial apophysis lacking basal apophysis (vs. present) and the embolus arising from a 3 o’clock (vs. other positions).

Description.

Female. Habitus (Fig. 1A, B View Figure 1 ). Total length 5.85. Carapace length 2.37, width 2.69, with many short club-shaped setae. Eye diameters and interdistances: AME 0.05, ALE 0.09, PME 0.05, PLE 0.07; AME-AME 0.25, ALE-AME 0.18, ALE-ALE 0.67, PME-PME 0.23, PLE-PME 0.35, PLE-PLE 1.02, AME-PME 0.27, AME-PLE 0.47, ALE-PLE 0.20, MOA 0.36 long, front width 0.35, back width 0.33. Chelicerae yellow, straight, robust, with several thick setae on frontal surface, lacking promarginal and retromarginal teeth. Endites yellow, with a distinct constriction medially, anterolaterally fan-shaped. Labium oval, longer than 2/3 of endite. Sternum (Fig. 1B View Figure 1 ) yellow, broadly oval, slightly longer than wide. Legs yellow (Fig. 1A, B View Figure 1 ), without annulation, measurements (Fig. 1A, B View Figure 1 ): I 8.75 (2.8, 1.44, 2.37, 1.41, 0.73); II 9.08 (2.74, 1.51, 2.41, 1.67, 0.75); III 5.36 (1.7, 0.82, 1.3, 0.91, 0.63); IV 5.05 (1.99, 0.83, 1.27, 0.55, 0.41); setation (Fig. 1A, B View Figure 1 ): I Fe: d1, p1; Pa: d1; Ti: v8; Mt: p2, r1, v12; II Pa: d1; Pa: d1; Ti: v8; Mt: p1, r1, v12; III Ti: d1; Mt: d1; IV: Ti: d1; Mt: d1.

Epigyne (Fig. 1C, D View Figure 1 ). Median plate (MP) triangular, copulatory openings (CO) located posterolateral of median plate. Copulatory ducts (CD) relatively long, as long as spermathecal length, slightly separated. Spermathecae (Spe) sac-shaped, slightly curved, with several constrictions. Fertilization ducts (FD) short and broad, directed laterally.

Male. Habitus (Fig. 2A, B View Figure 2 ). As in female except as follows. Total length 3.53. Carapace (Fig. 2A View Figure 2 ) length 1.56, width 1.73, with several erect club-shaped setae.

MOA 0.29 long, front width 0.26, back width 0.26. Chelicerae yellow, straight, robust, with abundant thick setae on frontal surface, lacking promarginal and retromarginal teeth. Endites yellow, with a distinct constriction medially. Labium trapezoidal. Legs yellow (Fig. 2A, B View Figure 2 ), legs I and II without annulations on patellae, tibiae, metatarsi, and tarsi; measurements: I 8.86 (2.7, 0.84, 2.25, 1.96, 1.11); II 7.67 (1.9, 0.82, 2.3, 1.84, 0.81); III 3.2 (0.95, 0.44, 0.82, 0.56, 0.43); IV 3.44 (1.12, 0.54, 0.93, 0.45, 0.4); setation (Fig. 2A, B View Figure 2 ): I Ti: d2, p1, r2, v5; Mt: p1, r2, v8; II Fe: d5; Ti: d3, p2, r1, v4; Mt: v10; III Fe: d3; Pa: d1; Ti: d3; IV: Fe: d2; Pa: d1, r1; Ti: d4; Mt: p1, r1. Abdomen (Fig. 2A, B View Figure 2 ) oval, 1.97 long, 1.19 wide, yellowish to yellow.

Palp (Fig. 2C-E View Figure 2 ). Ventral tibial apophysis (VTA) slightly shorter than tibia, directed anteriorly. Retrolateral tibial apophysis (RTA) longer than tibia, sub-medial part sharply pointed, with a thick spine-like tip. Embolus (Em) arising from 6 o’clock and ending at about 2 o’clock.
