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.
