( Figs 7 View FIGURE 7 , 13 View FIGURE 13 D–F, 14F, 14I, 14V, 15)

Batraxis tibialis Wang and Yin (in Wang et al. 2016: 4)   .

Type locality: China, Hainan, Qiongzhong Hsien, Limu Mt. , 19°10'04"N, 109°44'45"E, 625 m. GoogleMaps  

Additional material examined. 2 ƋƋ, labeled ‘ CHINA: W. Jiangxi, Ji’an City, Jinggang Shan (井冈山), Bijia Shan (笔架山), 26°31'03"N, 114°11'17"E, mixed leaf litter, sifted, 580 m, 24.vii.2014, Chen, Hu, Lv & Yu leg.’ ( SNUC). GoogleMaps  

Comments. The glabrous body ( Fig. 7 View FIGURE 7 A), obliquely narrowed abdomen at base, distinctly concaved protibiae ( Fig. 14 View FIGURE 14 F), presence of small ventral protuberance at the middle of profemora ( Fig. 14 View FIGURE 14 I), and the form of aedeagus ( Figs 13 View FIGURE 13 D–F) of the population from Jiangxi readily lead its identity to B. tibialis   . The differences in the forms of the protibial cavity and aedeagal endophallus between the populations from Hainan ( Fig. 7 View FIGURE 7 B) and Jiangxi is considered intraspecific variation of this species.

Measurements of the population from Jiangxi: BL 1.93 mm, HL 0.42 mm, HW 0.43 mm, PL 0.38 mm, PW 0.42 mm, EL 0.53 mm, EW 0.72 mm, AL 0.60 mm, AW 0.69 mm, mm, width between discal carinae of tergite IV 0.30 mm at apices, length of the aedeagus 0.24 mm.

Distribution. China: Jiangxi (new provincial record), Hainan ( Fig. 15 View FIGURE 15 ).
