Left chelicera (anterior and posterior views). Abbreviations: Ba = bulbal apophysis; Em = embolus; Ro = round membranous outgrowth. Scales: 0.4 mm (A–C); 0.1 mm (D–H). Type material. Holotype : Male (SYNU-532), Guangdong Province , Heyuan City , Xinhuilong Town , Dongxing Village , Wanlvgu Resort Area , 23°42′51″N , 114°38′9″E , elevation 180 m , W. Cheng , Y. Huang , K. Yang and T . Jiang leg., 23 April 2021 . Paratypes : 2 females (SYNU-533-534), same data as holotype . Etymology. The specific name is a noun in apposition and refers to the type locality. Diagnosis. The new species is similar to Apneumonella taitatavetaensis Zhao & Li, 2017 in the belt-shaped tibial glands and the bulbal tegular apophysis, but the male can be distinguished by lacking the dorsal mark on the abdomen (see Fig. 1A , vs with a yellow spot, see Song et al. 2017 : fig. 4A) and the shape of the bulbal tegular apophysis, which consist of a broad leaf-shaped and a needle leaf-shaped lobes ( Fig. 2A, B, E , vs finger-shaped, see Song et al. 2017 : figs 5A, C), and the female by lacking the hump on the abdomen ( Fig. 3A , vs with two anterior hump on the abdomen, see Song et al. 2017 : fig. 6A) and the cochlear-shaped receptacle ( Fig. 3E , vs baglike, see Song et al. 2017 : fig. 6C).
