Bolitogyrus hainanensis Cai et al., 2015: 457.

Type locality.

Mt. Yingge Ling [base of], Hainan, China.

Type material.

The type series of this recently described, and well-illustrated species was not examined ( Cai et al. 2015).

Diagnosis.

This species may be recognized by the following: head entirely dark; pronotum widest in posterior third; elytra partly dark, discal markings of elytra extending onto epipleuron, not forming v-shape, medial and lateral markings of different sizes and never entirely fused (Fig. 5G); hind femur with dark marking on ventral portion only (as in Fig. 2C; antennomere 7 distinctly transverse (Fig. 6F).

Distribution.

Figure 22B. This species may be endemic to Hainan island, China.

Bionomics.

Specimens have been collected in November and December at elevations ranging from 450-666 m.

Comments.

Except for one, much larger, member of the Carnifex Group, B. hainanensis is presently the only species of Bolitogyrus on Hainan island, China. Bolitogyrus hainanensis is externally similar to B. vulneratus and B. pecki but differs by the bilobed paramere, presence of a medial group of peg setae and the recurved apex of the median lobe in lateral view.
