Genus Lysania Thorell, 1890 View in CoL
Type species. Lysania pygmaea Thorell, 1890 .
Diagnosis. Lysania appears closely related to Zoica (Lehtinen & Hippa 1979; Hippa & Lehtinen 1983), as both genera share the distal origin of the embolus in the male pedipalp and the absence of a median apophysis (Framenau et al. 2009). However, the genus differs by the beak-like lateral apophysis, wider conductor and longer copulatory ducts. Additionally, males of Lysania have an abdominal scutum dorsally or a sclerotised dorsum, with a metallic luster. Spiders live in small sheet-webs, which are apparently absent in Zoica .
Distribution. Malaysia (Thorell 1890; Lehtinen & Hippa 1979), Borneo (Lehtinen & Hippa 1979) and China (this study).
Remark. Our examination on two Chinese Lysania species confirmed 6 (occasionally 5 or 7) cheliceral retromarginal teeth present. This is unique character among Lycosidae and might be diagnostic. More Lysania specimens from other countries should be checked.

Type material. Holotype male, China, Yunnan Province, Dehong Dai and Jingpo Autonomous Prefecture, Ruili City, Mengxiu Town, Nangsang Village, rubber plantation, 24°01′28.08″N, 97°49′08.1″E, alt. 820m, 4 June 2011, Z.X. Li & G.C. Zhou leg. (SWUC). Paratypes: 5 males and 18 females, same data as holotype (SWUC).
Etymology. The specific name comes from the word “De'ang”, the name of one of the Chinese ethnic minorities that live adjacent to the area inhabited by the new species; noun in apposition. Diagnosis. Lysania deangia is similar to L. pygmaea ( Figs 3 View FIGURE 3 A – D, 4E – H), but differs by the broad and strong lateral apophysis, inflated at the base, shorter embolus ( Figs 1 View FIGURE 1 A – B, 2G – H) and straight stalk of spermatheca ( Figs 1 View FIGURE 1 C – D, 2I – J).
Description. Males total length 4.39–6.08. Holotype ( Figs 2 View FIGURE 2 B – C, 2E–F) total length 4.39. Prosoma 1.96 long, 1.37 wide; opisthosoma 2.23 long, 1.10 wide. Dorsum of prosoma unicolorous dark, except for light posterior stripe behind fovea. Eye region black, with dense white setae. Fovea longitudinal. Cervical groove and radial furrows indistinct. Eye sizes and interdistances: AME 0.07, ALE 0.06, PME 0.16, PLE 0.11; AME–AME 0.04, AME–ALE 0.06, PME–PME 0.11, PME–PLE 0.13. Clypeus height 0.07. Chelicerae elongate, blackish-brown, with three promarginal and six retromarginal teeth. Labium yellow-brown, with darker 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 6.50 (1.74, 2.25, 1.47, 1.04); II 5.57 (1.54, 1.83, 1.35, 0.85); III 5.18 (1.40, 1.61, 1.34, 0.83); IV 7.89 (2.01, 2.45, 2.25, 1.18). Leg formula: 4123. Opisthosoma oval. Dorsum black, with blue metallic luster and sparse brown setae. Venter yellow-brown.
Male pedipalp ( Figs 1 View FIGURE 1 A–B, 2G–H). Lateral apophysis beak-like, with a broad base. Embolus short. Conductor wide and membranous.
Female (paratype, Figs 2 View FIGURE 2 A, 2D) total length 3.77. Prosoma 1.70 long, 1.15 wide; opisthosoma 1.84 long, 1.14 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 5.44 (1.49, 1.83, 1.24, 0.88); II 3.97 (1.12, 1.23, 0.91, 0.71); III 4.68 (1.34, 1.41, 1.19, 0.74); IV 7.33 (1.85, 2.34, 2.14, 1.00). Leg formula: 4132. Chelicerae with three promarginal and six retromarginal teeth (two females with 5 retromarginal teeth and one female with 7 ones). Opisthosoma oval. Dorsum black-brown. Venter yellow-brown.
Epigyne ( Figs 1 View FIGURE 1 C–D, 2I –J). Copulatory openings located posteriorly, small and widely separated. Heads of spermathecae rounded. Stalks of spermathecae long and twisted.
Distribution. Known only from the type locality in Yunnan province, China ( Fig. 7 View FIGURE 7 ).
