Type material.
Holotype ♂ and paratype 1 ♀. ( Syn-01 , ASM-JGSU). CHINA: • Fujian Prov., Zhangzhou City, Nanjing Co., Huboliao Nature Reserve , Huboliao area , 24°31'2.88"N, 117°14'53.47"E, 357 m a. s. l., 3.IV.2024, Y. B. Yao et al. leg. GoogleMaps
Diagnosis.
The new species is similar to H. bowoensis Ballarin & Li, 2015 and H. mangunensis Lin, Ballarin & Li, 2016 ( Ballarin and Li 2015: 180, fig. 1 A-D; Lin et al. 2016: 17, fig. 5 A-D) in having a clip-like terminal apophysis of the tegulum and a filamentous embolus, but can be separated from it by the large hook-shaped distal process of the paracymbium (vs. very tiny in H. bowoensis and H. mangunensis ), a hook-shaped terminal apophysis II of the tegulum with a strongly curved apex (vs. without apex in both H. bowoensis and H. mangunensis ), and the thick and finger-like ventral conductor processes I (vs. hook-like in H. bowoensis and H. mangunensis ) (Fig. 2 A-F View Figure 2 ). The female of the new species resembles that of H. luzon Lin, Ballarin & Li, 2016 ( Lin et al. 2016: 15, fig. 4 D-F) in having almost round spermathecae and the shorter, narrower fertilization ducts, but can be distinguished by the epigynal plate width 2.8 times smaller than the spermathecal diameter (vs. 2.3 times) and the touching spermathecae (vs. slightly separated) (Fig. 3 A, B View Figure 3 ).
Description.
Male (holotype). Habitus as in Fig. 1 A, B View Figure 1 . Total length 1.28, carapace 0.66 long, 0.6 wide. Eye sizes and interdistances (Fig. 1 A View Figure 1 ): AME 0.02, ALE 0.07, PME 0.06, PLE 0.07, AME - AME 0.06, AME - ALE 0.02, PME - PME 0.05, PME - PLE 0.05, AME - PME 0.03, AME - PLE 0.03, ALE - ALE 0.06, PLE - PLE 0.26, ALE - PLE 0.26. MOA 0.13 long, front width 0.11, back width 0.17. Endites trapezoidal, longer than wide, with dense setae arranged on the superomedial surface. Labium trapezoidal, wider than long, fused with sternum. Sternum (Fig. 1 B View Figure 1 ) subtriangular shield-shaped, nearly as long as wide, lateral margin with scattered long setae. Legs (Fig. 1 A, B View Figure 1 ): with abundant short setae; measurements: I 2.36 (0.72, 0.2, 0.21, 0.83, 0.4); II 2.42 (0.67, 0.29, 0.55, 0.45, 0.46); III 1.7 (0.38, 0.15, 0.49, 0.36, 0.32); IV 2.63 (0.82, 0.26, 0.66, 0.44, 0.45). Abdomen (Fig. 1 A, B View Figure 1 ) 0.64 long, 0.53 wide.
Coloration (Fig. 1 A, B View Figure 1 ). Carapace yellow to light brown. Chelicerae yellow. Endites and labium yellowish to yellow. Sternum yellow to dark brown, with many dark brown spots on the surface. Legs yellow. Abdomen yellowish to dark, mottled, sub-anteriorly with a transversal light-yellow stripe.
Palp (Fig. 2 View Figure 2 ). Long lateral cymbial furrow on the retrolateral side of the cymbium. Paracymbium dorsal apophysis translucent and subtriangular, shorter than ventral apophysis, ventral apophysis tongue-shaped, as long as distal process of paracymbium, distal process hook-shaped, relatively large, slightly sclerotized. Terminal apophysis of tegulum well-developed and strongly sclerotized, with 2 curved processes forming together clip-like structure, terminal apophysis I of tegulum fang-like, terminal apophysis II of tegulum hook-shaped, with strongly curved apex. Conductor with 2 ventral processes distally, processes of the conductor I thick and finger-like, processes of the conductor II blunt and laminar, forming a C-shaped groove. Embolus filamentous, clockwise spiraling nearly 4 / 5 coil, arising from ~ 3 o’clock and ending at ~ 1 o’clock on tegulum.
Female (paratype). Habitus as in Fig. 1 C, D View Figure 1 . As in male, except as noted. Total length 1.79, carapace 0.63 long, 0.63 wide. Eye sizes and interdistances (Fig. 1 C View Figure 1 ): AME 0.05, ALE 0.06, PME 0.05, PLE 0.07, AME - AME 0.03, AME - ALE 0.02, PME - PME 0.05, PME - PLE 0.03, AME - PME 0.04, AME - PLE 0.09, ALE - ALE 0.15, PLE - PLE 0.21, ALE - PLE 0.01. MOA 0.13 long, front width 0.11, back width 0.15. Legs (Fig. 1 C, D View Figure 1 ): measurements: I 1.55 (0.75, 0.23, 0.57, missing); II 2.33 (0.6, 0.27, 0.56, 0.5, 0.4); III 1.96 (0.58, 0.21, 0.38, 0.21, 0.58); IV 2.81 (0.84, 0.29, 0.7, 0.45, 0.53). Abdomen (Fig. 1 C, D View Figure 1 ) 1.16 long, 1.04 wide, with several long setae evenly.
Coloration (Fig. 1 C, D View Figure 1 ). Carapace yellow to reddish brown. Chelicerae, endites and labium reddish brown. Sternum yellow to reddish brown. Abdomen light yellow.
Epigyne (Fig. 3 View Figure 3 ). Translucent, more than 1.5 times wider than long. Spermathecae almost round, diameter subequal to half genital plate width, strongly sclerotized and touching each other. Copulatory ducts short, subequal to half spermathecal diameter, forming a C-shaped loop between the copulatory openings and the spermathecal base. Fertilization ducts narrow, connected to the base of the spermathecae and directed laterally.
Habitat.
In the tree near the ravine stream.
Distribution.
Known only from Fujian Province, China.
Etymology.
The name is taken from Qingming Festival (清明节), referring to the period of specimen collection during traditional Chinese Tomb-Sweeping Day; noun in apposition.
