Lysania pygmaea Thorell, 1890: 313; Roewer 1960: 973; Lehtinen & Hippa 1979: 14, figs 4, 10, 49, 52–54, 63, 68. Anomalomma pygmaeum Roewer, 1955: 310.
Material examined. 13 males and 40 females, China, Yunnan Province, Hekou County, Huayudong National Forest Park, 22°40′9.24″N, 103°56′11.34″E, alt. 130 m, 14 May 2011, Z.X. Li & G.C. Zhou leg. (SWUC); 2 males, Yunnan Province, Puer City, 20 June 2008, Z.Z. Yang leg. (DLU); 1 male, Guangxi Province, Ningming County, Tongmian Town, 17 May 2006, M.S. Zhu leg. (MHBU).
Diagnosis. Similar to L. deangia (Figs 1 A–D, 2G–J), but males can be differentiated by the small lateral apophysis and slender embolus (Figs 3 A–B, 4G–H) and females by the long copulatory ducts (Figs 3 C–D, 4E–F).
Description. Male (Figs 4 B – C). Total length 3.78. Prosoma 1.77 long, 1.27 wide; opisthosoma 1.92 long, 0.93 wide. Dorsum of prosoma unicolorous dark, except for light posterior stripe behind fovea. Eye region black, with bushy white setae. Fovea longitudinal. Cervical groove and radial furrows indistinct. Eye sizes and interdistances: AME 0.06, ALE 0.06, PME 0.14, PLE 0.11; AME–AME 0.04, AME–ALE 0.05, PME–PME 0.12, PME–PLE 0.13. Clypeus height 0.07. Chelicerae elongate, black-brown, with three promarginal and six retromarginal teeth. Labium yellow-brown, with dark base, longer than wide. Endites yellow-brown, longer than wide. Sternum black brown, shield-shaped, with sparse brown setae. Legs yellow brown, with black pigmentation. Leg measurements: I 6.26 (1.67, 2.10, 1.45, 1.04); II 5.25 (1.40, 1.71, 1.29, 0.85); III 4.98 (1.35, 1.53, 1.32, 0.78); IV 7.57 (2.00, 2.29, 2.16, 1.12). Leg formula: 4123. Opisthosoma oval. Dorsum black, with metallic bright and sparse brown setae. Venter yellow-brown.
Male pedipalp (Figs 3 A–B, 4G–H). Lateral apophysis narrow, beak-like, base of lateral apophysis broad. Embolus thin and long. Conductor wide and membranous.
Female (Figs 4 A, 4D) total length 3.73. Prosoma 1.70 long, 1.26 wide; opisthosoma 2.05 long, 1.34 wide. Eye sizes and interdistances: AME 0.05, ALE 0.06, PME 0.18, PLE 0.13; AME–AME 0.01, AME–ALE 0.05, PME– PME 0.11, PME–PLE 0.16. Clypeus height 0.05. Leg measurements: I 4.80 (1.37, 1.62, 1.05, 0.76); II 4.04 (1.11, 1.34, 0.91, 0.68); III 4.00 (1.16, 1.26, 0.98, 0.60); IV 5.96 (1.58, 1.87, 1.64, 0.87). Leg formula: 4123. Opisthosoma oval. Dorsum black brown, without metallic shine. Venter yellow-brown.
Epigyne (Figs 3 C–D, 4E–F). Copulatory openings posteriorly located, small and widely separated. Heads of spermathecae rounded. Stalks of spermathecae thin, long and curved in the middle.
Distribution. Malaysia (Thorell 1890) and Southwest of China (Fig. 7).
Remarks. The type materials of L. pygmaea were unavaible for this research. We compared our specimens with the figures of L. pygmaea in Lehtinen & Hippa (1979: 14, figs 4, 10, 49, 52–54, 63, 68), all the structures of male pedipalp were the same, except the shape of the conductor. Based on our specimens, the conductor is membranous, transparent and folded, which explains the differences to the drawings of Lehtinen & Hippa (1979). Epigyne of this species was too small to clear. We compared our photo (Fig. 4 E) with the figure of Lehtinen & Hippa (1979: 13, fig. 54) and we believe they are the same species.
