Figs 1, 7 (顶突百越蛛)

Draconarius acroprocessus Zhang, Zhu & Wang in Zhu et al. 2017: 220, fig. 107A-C (♂).

Material examined.

1 male (holotype, SWUC-T-AG-19-01): China, Hubei Province, Xuanen County, Jiaoyuan Town, 30 Augustus 2004, Z.S. Zhang & H.M. Chen leg.

Diagnosis.

Male resembles that of B. zhuping Zhao, Li & Li, 2023 in having the similar patellar apophysis with a pointed distal end, cymbial furrow almost half the length of cymbium (Fig. 1; Zhao et al. 2023: fig. 5A-C), but B. acroprocessus comb. nov. can be distinguished from the latter by the following: conductor dorsal apophysis with bifurcated apex and strongly sclerotized (Fig. 1A-C) vs unbifurcated in B. zhuping (Zhao et al. 2023: fig. 5A-C); embolic base margin serrated in retrolateral view (Fig. 1A-C) vs embolic base smooth in B. zhuping (Zhao et al. 2023: fig. 5A-C); cymbial base with two hypophyses (Fig. 1A-C) vs with one hypophysis in B. zhuping (Zhao et al. 2023: fig. 5A-C).

Description (partial).

Pedipalp (Fig. 1A-C): patellar apophysis thumb-shaped with pointed end; retrolateral tibial apophysis originating from midway along length of tibia; lateral tibial apophysis somewhat triangular, with blunt end; cymbial furrow half as long as cymbium; cymbial base with two hypophyses; median apophysis spoon-like; embolus originating at 7 o’clock; conductor translucent, with smooth, wrinkled surface and serrated margin; conductor dorsal apophysis with bifurcated apex and strongly sclerotized. Habitus as shown by Zhu et al. (2017). Female unknown.
