Name
Bolitogyrus sepilok Brunke sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type locality
Sepilok Nature Resort, Sabah, Borneo, Indonesia.
Type material
Holotype (♂, cRou): SABAH, Sepilok N.R., in fungi on log, 13.II.2007, G. de Rougemont leg. [printed] / Bolitogyrus sp. Det. 2009, G. de Rougemont [printed] / HOLOTYPE Bolitogyrus sepilok Brunke, des. A. Brunke 2017 [red label] / AJB0000437 [identifier label].
Diagnosis
This species is easily distinguished by the combination of the orange head and pronotum, transverse and raised yellow marking on the elytra (as in Figs 2A, 4H) and the abdominal tergites with deeply impressed and elongate punctures (Fig. 5A).
Description
Measurements ♂ (n = 1): HW/HL 1.30; PW/PL 1.24; EW/ EL 1.24; ESut/PL 0.86; PW/HW 0.96; forebody length 4.3 mm.
Similar to B. luteus and differing only in the following: body with pale areas darker, dark reddish; abdominal tergites I-III with broad medial dark markings; palpi slightly darker; forecoxa with small dark marking at midlength; femur with dark subapical band, apex of hind tibia dark; antennomeres 1-3 orange with slightly darkened apices, 4-8 dark brown, 9 light brown, 10-11 light yellow; pronotum distinctly more elongate and strongly convex; pronotum relatively narrower than head; forebody length smaller; abdominal tergites III-VI with deeply impressed and elongate punctures in basal impressions; median lobe in lateral view with much larger expansion
in lateral view, with pair of broad basal teeth (Fig. 13F); median lobe in parameral view with basal teeth appearing medially, apical portion shorter and only slightly acuminate (Fig. 13E); paramere shorter than median lobe, narrower with smaller expansion, peg setae in broad single row reaching midlength, distant from midline (Fig. 13G).
Distribution
Figure 19C. Known only from the type locality in northeastern Borneo but probably more widely distributed in remnant lowland forests.
Bionomics
Bolitogyrus sepilok was collected from fungi on a log in February at a lowland elevation.
Etymology
In recognition of the Kabili-Sepilok Forest Preserve, which adjoins the type locality and preserves a significant remnant of virgin lowland Dipterocarp forest in northern Borneo.
Comments
Bolitogyrus sepilok can be recognized by its distinct habitus alone.
