Diagnosis.

This species can be distinguished by the following character states: head entirely dark; elytral disc dark with pale markings not extending onto epipleuron (Fig. 5F); pronotal margin at its widest point no more than three lateral puncture widths wide but still distinctly expanded at hind angles (Fig. 5F); hind tibia at least partly darker than pale region of femur; head with discal punctures and frontal impression extremely shallow.

Redescription.

Measurements ♂ (n = 4): HW/HL 1.33-1.38; PW/PL 1.10-1.20; EW/ EL 1.14-1.19; ESut/PL 0.84-0.86; PW/HW 0.95-0.99; forebody length 3.8-4.4 mm.

Measurements ♀ (n = 5): HW/HL 1.32-1.40; PW/PL 1.13-1.23; EW/ EL 1.15-1.19; ESut/PL 0.82-0.90; PW/HW 0.94-1.04; forebody length 4.4-4.6 mm.

Similar to B. elegans and differing only in the following: head and pronotum entirely dark; elytral dark, v-shaped marking often broken into two markings, outer marking usually elongate and inner marking loosely triangular (Fig. 5F); leg color variable, coxae almost entirely pale to entirely dark, femora yellow with dark apical band or with only small ventroapical spot, tibia entirely dark to light brownish in faded specimens; antennomeres 6-10 more transverse, 10 not more elongate than 9; disc of head with punctures smaller and far more shallow; pronotum more variable in shape but slightly more transverse, elytral suture longer relative to pronotum at middle; basal impressions of abdomen with elongate to regular punctures, depending on specimen; paramere slightly longer than median lobe, with long apical portion not projected over apex of median lobe (Fig. 18E); peg setae rows strongly convergent (Fig. 18F); female tergite X with longer apical projection.

Distribution.

Figure 20A. Known from the mountains encircling the Bandung City area of West Java.

Bionomics.

Specimens have been collected in January and June-August, at elevations ranging from 1000-1700 m.

Comments.

Bolitogyrus ornatipennis is externally most similar to allopatric B. lasti (southern India) but can be distinguished by the more triangular median elytral marking and the distinct expansion of the pronotal margin.
