Figs 5A-C View Figure 5 , 6A, B View Figure 6 , 8A, B View Figure 8

Type material.

Holotype: ♂ (IZCAS-Ar44437), China, Yunnan: Menglun Town: Xishuangbanna, Tropical Botanical Garden, 21.9238°N, 101.2740°E, ca 598 m, 1-15.VII.2007, secondary tropical seasonal rain forest, Guo Zheng leg. Paratypes: 5♂6♀ (IZCAS-Ar44438-Ar44448), same data as holotype.

Diagnosis.

The male of Hongkongia liutang sp. nov. is similar to these of H. wuae Song & Zhu, 1998 and H. reptrix Deeleman-Reinhold, 2001 by the helical conductor (Fig. 5B View Figure 5 ). Females of the new species are similar to those of H. reptrix by having copulatory ducts subparallel in the middle and close to each other (Fig. 6B View Figure 6 ). However, the new species can be distinguished from H. wuae by having retrolateral tibial apophysis as long as tibia (Fig. 5C View Figure 5 ) [vs retrolateral tibial apophysis longer than tibia (see Kamura 2019: fig. 2G) and with an outgrowth pointing dorsally (see Song and Zhu 1998: fig. 4E)] and tip of conductor with serrations (Fig. 5B View Figure 5 ) (vs serrations absent in other congeners). The female of new species can be distinguished from those of H. reptrix by the having two hoods (Fig. 6B, C View Figure 6 ) [vs only one hood (see Zhang et al. 2009: figs 12, 13)].

Description.

Male holotype (Fig. 8A View Figure 8 ). Total length 2.84; carapace 1.45 long, 1.06 wide, opisthosoma 1.42 long, 0.90 wide. Eye sizes and interdistances: AME 0.04, ALE 0.05, PME 0.05, PLE 0.04, AME-AME 0.01, AME-ALE 0.01, PME-PME 0.02, PME-PLE 0.01, AME-PME 0.02, ALE-PLE 0.02. Anterior eye row almost straight, posterior eye row recurved. Chelicerae with three promarginal and one retromarginal teeth. Leg measurements: I 4.60 (1.23, 1.80, 0.89, 0.68), II 3.60 (0.98, 1.31, 0.68, 0.63), III 3.10 (0.89, 0.95, 0.73, 0.53), IV 4.15 (1.07, 1.37, 1.00, 0.71). Opisthosoma oval, without scutum, venter dark brown. Spinnerets pale yellow.

Palp (Fig. 2A-C View Figure 2 ). Femur unmodified. Tibia slightly shorter than patella. Retrolateral tibial apophysis (RTA) 2 × shorter than tibia, tip blunt. Cymbium almost 2 ×longer than wide. Subtegulum absent. Tegulum (T) obvious, almost 1.5 × wider than long in ventral view. Conductor (C) and embolus (E) have the same base. Conductor helically twisted, middle with an apophysis, terminal serrated, slightly curved. Embolus directed at 5 o’clock position, whiplike.

Female paratype (IZCAS-Ar44444) (Fig. 8B View Figure 8 ). Total length 4.07; carapace 1.68 long, 1.28 wide, opisthosoma 2.48 long, 1.53 wide. Eye sizes and interdistances: AME 0.13, ALE 0.12, PME 0.12, PLE 0.11, AME-AME 0.02, AME-ALE 0.01, PME-PME 0.04, PME-PLE 0.02, AME-PME 0.06, ALE-PLE 0.02. Chelicerae with three promarginal and one retromarginal teeth. Leg measurements: I 4.27 (1.24, 1.54, 0.83, 0.66), II 3.55 (1.08, 1.21, 0.70, 0.56), III 3.32 (1.00, 1.08, 0.74, 0.50), IV 4.68 (1.23, 1.58, 1.21, 0.66). Opisthosoma oval, without scutum, venter yellow-brown. Spinnerets pale yellow.

Epigyne (Fig. 6A, B View Figure 6 ). Epigynal plate 1.5 × longer than wide, with a pair of hoods (H) anteriorly, hoods almost triangle shaped. Copulatory openings (CO) strongly sclerotized. Copulatory ducts (CD) intertwined. Spermathecae (S) oval. Fertilization ducts (FD) sickle-shaped, directed at 4 o’clock position from spermathecae.

Distribution.

Known only from the type locality.

Etymology.

The species is named after Liu Tang, one of the 108 outlaws in the classical Chinese novel 'Outlaws of the Marsh’; noun in apposition.
