Type locality.

Datang Village, Baoshan City, Tengchong County, Yunnan, China.

Type material.

Bolitogyrus huanghaoi Hu et al., 2011.

Holotype (♂, SNUC). CHINA: Yunnan Prov., Baoshan City, Tengchong County, Datang Village, 14-VI-2005, HUANG Hao leg. [printed] / “[Holotype]” Bolitogyrus huanghaoi , HU, LIU & LI, 2011 [red label] / AJB0000458.

Tentative identification.

MYANMAR: Kachin State: 3 km NW of 3 River Junction, 26.368 98.682, 2450 m, 3.X.2010, Michael Langer, S. Naumann and S. Löffler, 1 sex unknown [missing terminal segments], AJB0000459 (NMW).

Diagnosis.

Among the members of the Electus Group: head punctures clearly separated (Fig. 3E); elytra non-metallic; hind tibia entirely dark, as dark as darkened portion of femur (Fig. 3H); antennomere 6 weakly transverse, 7 distinctly transverse (4B); paramere slightly longer than median lobe, only slightly dilated and apex not attenuate (Fig. 8M); apex of median lobe in lateral view forming a more elongate triangle (Fig. 8N); median lobe without expansion in lateral view (Fig. 8N); peg setae absent from broad oval-shaped area along middle of paramere (Fig. 8O).

Redescription.

Measurements ♂ (n = 1): HW/HL 1.35; PW/PL 1.34; EW/ EL 1.23; ESut/PL 0.85; PW/HW 1.08; forebody length 4.9 mm.

Extremely similar to B. electus and differing only in the following: palpomeres and antennomeres 2-5 darker, reddish brown, antennomere 6 weakly transverse, 7 distinctly transverse (Fig. 4B), paramere much less dilated at apical third, apex not attenuate - evenly converging to apex (Fig. 8M), median lobe in lateral view without expansion (Fig. 8N), peg setae absent from oval-shaped area along middle of paramere, not appreciably grouped into marginal and medial fields (Fig. 8O).

Distribution.

Figure 19A. Known from a single locality in western Yunnan, China. A specimen from nearby in Myanmar is tentatively identified as this species but is missing the terminal segments of the abdomen.

Bionomics.

The holotype was collected at about 1600m in June.

Comments.

Bolitogyrus huanghaoi is most similar to B. confusus but they are distinctly allopatric and differ in the arrangement of peg setae of the paramere.
