Bolitogyrus depressus Cai et al., 2015: 454.

Type locality.

Nanling National Forest Park, Ruyuan County, Guangdong, 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); median lobe in lateral view projected ventrad, with hooked apex, basal teeth absent (Fig. 15F); median lobe in parameral view with apex acuminate (Fig. 15D); paramere shorter than median lobe (Fig. 15F) and at widest point slightly wider than median lobe in parameral view.

Distribution.

Figure 21D. Known only from the type locality in Guangdong, China.

Bionomics.

The holotype was collected in July.

Comments.

Although Cai et al. 2015 did not directly compare B. depressus to B. rufomaculatus , they are extremely similar. Unlike B. rufomaculatus , Bolitogyrus depressus does not bear basal teeth on the median lobe, has a large expansion on the median lobe in lateral view, and the paramere is shorter than the median lobe. One female specimen from low elevation (600 m) from Guizhou, China was examined (cShi) that could be this species.
