Bolitogyrus metallicus Cai et al., 2015: 466.

Type locality.

Shennongjia Nature Reserve, Pingqian, Hubei, China.

Type material.

The type series of this recently well illustrated ( Cai et al. 2015) species was not examined but the illustrations in the description ( Cai et al. 2015) and additional photos provided by the senior author of that paper were studied.

Diagnosis.

Among the members of the Electus Group: many head punctures confluent (Fig. 8F); elytra not metallic blue-green; median lobe in lateral view with only minute lateral teeth, with only slight subapical expansion (Fig. 9L, arrows); paramere distinctly longer than median lobe, weakly constricted in apical fourth (Fig. 9M), with peg setae at middle, on broad, medial ridge (Fig. 9O) and extended basad of marginal group (Fig. 9N).

Distribution.

Figure 19B. Known from a single locality in northwestern Hubei, China and is the easternmost described species of the Electus group.

Bionomics.

The holotype was collected in September but nothing more is known.

Comments.

Bolitogyrus metallicus is most similar to B. nigerrimus from Guizhou, China and can only be distinguished from it by characters on the aedeagus including the basally extended peg setae of the paramere, median ridge of the paramere and narrower apex of the median lobe in lateral view.
