Key to Chinese species of Bothropolys

To assist in the identification of the Chinese species of Bothropolys, the following key is offered. This key emphasizes characters that can be examined without much dissection or high-magnification microscopy; moreover, these characters are specific to the taxa occurring in China. The Chinese records of Bothropolys species are shown in Fig. 11.

1b. Porodont not present, 35 ocelli on each side, maxillipede dental margin with 9–10 teeth ........ B. montanus

2a. Porodont near the outer tooth, but not between the outer first and second teeth........................................ 3

2b. Porodont between the teeth......................................................................................................................... 5

3a. One terminal ocellus comparatively bigger than the others, posterior angles of TT 6 and 7 with feeble pro- jections........................................................................................................................................................ 4
