Bolitogyrus pecki Brunke View in CoL sp. n. (Fig. 17M-O, 22B (map))

Type locality.

BaBe National Park, Bac Kan Province, Vietnam.

Type material.

Holotype (♂, CNC): VIETNAM: Cao Bang [Bac Kan] Prov., BaBe Nat. Park, 7-11.V.97, 180 m / forest FITs, S. Peck, 97-2 / HOLOTYPE Bolitogyrus pecki Brunke, des. A. Brunke 2017 [red label] / CNC655574 [identifier label]

Diagnosis.

This species can be distinguished by the following character states: head entirely dark; elytral disc dark with pale markings extending halfway to epipleural margin (Fig. 5G), medial and lateral discal spots distinguishable and not forming distinct chevron or v-shaped marking or broad pale area; pronotal margin at its widest point no more than three lateral puncture widths wide but still distinctly expanded at hind angles; apex of hind femur with only vague dark marking on ventral margin; antennomere 7 distinctly transverse; paramere with distinct rows of peg setae (Fig. 17O).

Description.

Measurements ♂ (n = 1): HW/HL 1.40; PW/PL 1.31; EW/ EL 1.22; ESut/PL 0.83; PW/HW 1.06; forebody length 4.5 mm.

Similar to B. khasiensis and differing only in the following: medial and lateral elytral markings much more broadly connected, pale area of epipleuron not restricted to humeral spot, pale in up to entire basal half; abdomen slightly paler, dark reddish brown toward the base; head and pronotum more transverse; elytral suture relatively longer than pronotum at middle; forebody distinctly broader, appearing more robust; median lobe with laterally placed basal teeth, in parameral view with apex bearing folded, single-tooted carina (Fig. 17M); median lobe in lateral view only simple apical tooth, with basal teeth appearing removed from lateral margin (Fig. 17N); paramere with slender apical portion, with sparse marginal and medial rows of peg setae, apex with dense field placed close to margin, apical setae extremely small, almost unobservable at lower magnifications (Fig. 17O). Female unknown.

Distribution.

Figure 22B. Known only from northern Vietnam.

Bionomics.

The holotype was collected in May using an FIT in lowland forest (180 m).

Etymology.

This species is named in honor of Stewart Peck (Carleton University, Ottawa, Canada), the collector of its holotype and many other rare taxa belonging to Staphylinini .

Comments.

Bolitogyrus pecki is similar to the allopatric B. hainanensis from Hainan, China but can easily be distinguished by median lobe in lateral view, which is not recurved and the peg setae of the paramere, which are arranged in simple marginal and medial rows.
