Etymology. The specific name is a patronym in honor of Zhaoxu Nan, the author of Field Notes from A Natural Shenzhen, who advocates nature conservation for Shenzhen Special Economic Zone, and is a noun (name) in genitive case.

Diagnosis. This species can be easily distinguished from all known congeners by combination of following characters: procursus with large, angular, subdistal membranous lamella prolaterally (arrow in Fig. 3A View FIGURE 3 ) and with three separated sclerotized apophyses distally (arrows in Fig. 3C View FIGURE 3 ), epigynum with posterior lip (arrow in Fig. 4A View FIGURE 4 ), and vulval pore plates nearly triangular ( Fig. 4B View FIGURE 4 ).

Description. Male (holotype): Total length 2.34 (2.47 with clypeus), carapace 0.68 long, 0.93 wide, opisthosoma 1.66 long, 1.14 wide. Leg I: 16.75 (4.19 + 0.39 + 4.02 + 6.12 + 2.03), leg II: 11.34 (3.22 + 0.34 + 2.63 + 3.88 + 1.27), leg III: 9.12 (2.72 + 0.32 + 2.21 + 3.18 + 0.69), leg IV: 10.55 (3.03 + 0.33 + 2.56 + 3.74 + 0.89); tibia I L/d: 41. Distance PME-PME 0.11, diameter PME 0.13, distance PME-ALE 0.03, AME absent. Habitus as in Figs. 4 View FIGURE 4 E–F. Carapace yellowish, with dark brown margins and dark median line; ocular area dark brown; clypeus brownish, with dark brown marks laterally; sternum yellowish, with dark brown marks. Legs brownish, but whitish on distal parts of femora and tibiae, with darker rings on subdistal parts of femora and proximal and subdistal parts of tibiae. Opisthosoma yellowish, with large dark brown spots. Ocular area slightly elevated and separated from rest of carapace. Thoracic furrow shallow, but distinct. Sternum wider than long (0.58/0.52). Chelicerae ( Figs. 4 View FIGURE 4 C–D) with pair of proximo-lateral apophyses (without scales), pair of small distal apophyses laterally, pair of small frontal apophyses (arrows in Figs. 4 View FIGURE 4 C–D), and pair of long and hooked frontal apophyses (tips close together). Pedipalps as in Figs. 3 View FIGURE 3 A–B; trochanter with short retrolateral apophysis and small ventral apophysis; femur with retrolateral apophysis; patella large; procursus simple proximally but complex distally, with large, angular, subdistal membranous lamella prolaterally (arrow in Fig. 3A View FIGURE 3 ), three separated sclerotized apophyses distally (arrows in Fig. 3C View FIGURE 3 ) and distal membranous elements prolaterally provided with scales; bulb simple, no other projections except for embolus. Retrolateral trichobothrium of tibia I at 6% proximally; legs with short vertical setae on tibiae, metatarsi and tarsi, without spines and curved setae; tarsus I with 42 distinct pseudosegments.

Female: Similar to male, habitus as in Figs. 4 View FIGURE 4 G–H. Total length 2.68 (2.78 with clypeus), carapace 0.76 long, 0.96 wide, opisthosoma 1.92 long, 1.41 wide; tibia I missing. Distance PME-PME 0.09, diameter PME 0.11, distance PME-ALE 0.04, AME absent. Sternum wider than long (0.66/0.58). Epigynum ( Fig. 4A View FIGURE 4 ) brown, with posterior lip (arrow in Fig. 4A View FIGURE 4 ) and pair of pockets anterior to lip. Vulva ( Fig. 4B View FIGURE 4 ) with curved anterior arch and pair of nearly triangular pore plates.

Variation: Tibia I in the male from Maluan Mountain: 4.43. In another female paratype, tibia I: 3.58, tibia I L/d: 40.

Distribution. China (Guangdong, type locality; Fig. 1 View FIGURE 1 ).
