Type material.
Holotype ♂ (IZCAS-Ar41660), China: Yunnan, Xishuangbanna, Mengla County, Menglun Township, Menglun Nature Reserve, Xishuangbanna Tropical Botanical Garden, eastern part (21°54.07'N, 101°16.36'E, 544 m alt.), 16.VII.2018, X. Mi et al. leg. Paratypes: 2♀ (IZCAS-Ar41661-41662), same locality (21°54.07'N, 101°16.36'E, 544 m alt.), 22.VII.2018, X. Mi et al. leg.
Comparative material.
Eriovixia cavaleriei (Schenkel, 1963), 7♂ 4♀ (TRU), CHINA: Guizhou, Tongren, Bijiang District, Chuandong Township , Jianyan Village (27°50.85'N, 109°14.26'E, 480 m alt.), 27.IV.2019, X. Mi et al. leg GoogleMaps .
Etymology.
The specific name is the full name of Mr. Hong Liu (Tongren, China), one of the collectors of the type specimens; noun (name) in genitive case.
Diagnosis.
The female of E. liuhongi sp. nov. resembles those of E. kachugaonensis Basumatary et al., 2019 in general appearance, but can be distinguished from the latter by the: 1) spinnerets situated at posterior 1/3 of the abdomen vs. posterior 1/2 ( Basumatary et al. 2019: figs 5-6); 2) spermathecae kidney shaped vs. globular ( Basumatary et al. 2019: figs 10-13); 3) spermathecae touching each other vs. separated ( Basumatary et al. 2019: figs 10-13); and 4) copulatory ducts extend to the lateral edges of the epigyne vs. extended to the central part of the epigyne ( Basumatary et al. 2019: figs 10-13). The male and female resemble those of E. cavaleriei (Schenkel, 1963) by the shape of the copulatory organs, but can be distinguished by: 1) lacking a white stripe on the anterior edge of abdomen vs. 2 white stripes extending to the anterior edge ( Schenkel 1963: fig. 95a); 2) outline of the folium is wavy vs. deeply toothed ( Schenkel 1963: fig. 95a); 3) terminal apophysis fused with embolus at base vs. conspicuously separated; and 4) spermathecae kidney shaped vs. ovoid.
Description.
Male (Holotype, Figs 3A-D View Figure 3 , 17B View Figure 17 , 19B View Figure 19 ). Total length 2.70. Carapace 1.50 long, 1.30 wide. Abdomen 1.30 long, 1.00 wide. Clypeus 0.10 high. Eye sizes and interdistances: AME 0.08, ALE 0.05, PME 0.08, PLE 0.05, AME-AME 0.10, AME-ALE 0.15, PME-PME 0.10, PME-PLE 0.20, MOA length 0.28 with anterior width 0.28 and posterior width 0.28. Leg measurements: I 4.90 (1.60, 1.75, 1.10, 0.45), II 3.85 (1.25, 1.30, 0.90, 0.40), III 2.20 (0.75, 0.70, 0.45, 0.30), IV 3.60 (1.00, 1.15, 1.10, 0.35). Carapace yellow, cervical groove inconspicuous, lacking cephalic protuberance. Chelicerae and endites yellow, labium greyish-yellow, sternum yellow, with irregular dark patches and sparse darker setae. Legs yellow with dark rings. Abdomen oval, yellowish-white, dorsum with a large, pale folium and a large black spot posteriorly; ventre greyish-yellow, with pair of arcuate white patches and pair of white spots anterior to brown spinnerets.
Palp (Figs 3A, B View Figure 3 , 17B View Figure 17 ): median apophysis as wide as the bulb diameter, with 2 spurs prolaterally, retrolateral end curled; embolus straight, about half length of the terminal apophysis in prolateral view; terminal apophysis almost semicircular in prolateral view and fused with embolus at base; conductor flat, with a small tip in apical view.
Female (paratype IZCAS-Ar41661, Figs 3E, F View Figure 3 , 4 View Figure 4 , 20B View Figure 20 ). Total length 4.80. Carapace 1.80 long, 1.30 wide. Abdomen 3.50 long, 2.40 wide. Clypeus 0.08 high. Eye sizes and interdistances: AME 0.10, ALE 0.08, PME 0.10, PLE 0.05, AME-AME 0.13, AME-ALE 0.18, PME-PME 0.13, PME-PLE 0.23, MOA length 0.28 with anterior width 0.28 and posterior width 0.28. Leg measurements: I 5.05 (1.60, 1.85, 1.15, 0.45), II 4.50 (1.35, 1.55, 1.15, 0.45), III 2.55 (0.85, 0.85, 0.50, 0.35), IV 4.10 (1.30, 1.45, 0.95, 0.40). Habitus similar to that of male but the outline of the dorsal abdominal folium more obvious.
Epigyne (Fig. 4 View Figure 4 ) about 1.4 times longer than wide; scape triangular, narrowed near tip, copulatory openings arcuate; copulatory ducts very long, directed towards lateral margin; spermathecae long, kidney shaped, touching each other.
