Diagnosis
This species may be recognized by the following: head entirely dark; pronotum widest in posterior third; elytra partly dark, base of elytra with broad pale area composed entirely of pale, raised yellow marking extending onto epipleuron (Fig. 2C, 6C); elytra with punctures along sutural area (Fig. 6C); paramere not constricted apically (Fig. 13L); female tergite VIII with wide triangular emargination (Fig. 7B).
Redescription
Measurements ♂ (n = 5): HW/HL 1.31–1.38; PW/PL 1.31–1.39; EW/ EL 1.19–1.28; ESut/PL 0.75–0.81; PW/HW 1.04–1.08; forebody length 4.6–4.7 mm.
Measurements ♀ (n = 5): HW/HL 1.33–1.39; PW/PL 1.29–1.38; EW/ EL 1.18–1.25; ESut/PL 0.74–0.80; PW/HW 1.06–1.07; forebody length 4.2–4.9 mm.
Similar to B. vulneratus and differing only in the following: elytra with broad basal area composed entirely of raised yellow marking, pale area variable, as large spot extending to apical two-thirds (Fig. 6C) to extended to almost entire disc and leaving only apical angles dark (Fig. 2C); dark markings on femoral apices slightly larger on some specimens but never including dorsal face; head less transverse; antennomeres 7-10 distinctly transverse (Fig. 6F); pronotum more transverse; abdominal tergite VI not or only narrowly impunctate at middle; median lobe in lateral view with basal teeth formed as wide, toothed ridge (Fig. 13N); median lobe in parameral view with basal teeth barely visible, apical portion elongate and expanded, then suddenly constricted to acuminate and narrow apex (Fig. 13M); paramere elongate spoon-shaped (Fig. 13L), peg setae arranged in wide marginal group, convergent basally (Fig. 13O).
Distribution
Figure 22A. Bolitogyrus flavus is widely distributed over the mainland of the southeast Oriental region.
Bionomics
As far as known, B. flavus is a lowland to lower montane species and does not occur above 1000 m. Specimens have been collected in all months except February and September. Bolitogyrus flavus has been collected from fungi and rotten wood.
Comments
Bolitogyrus flavus is the most commonly collected species of the genus in the Oriental region. Several single females could extend its range even further but may actually represent other related species.
