Type locality
Mintaingbin Forest Camp, ca. 35 km north of Aungban, Shan State, Myanmar.
Type material
Holotype (♂, NMW): MYANMAR: Shan State (MBS 146a), ca 35 km N Aungban, Mintaingbin Forest Camp, FIT, 20°55.20'N 96°33.60E, 11-23.6.2004, ca. 1320m [printed] / HOLOTYPE Bolitogyrus schillhammeri Brunke, des. A. Brunke 2017 [red label] / AJB0000413 [identifier label].
Paratypes (6 ♂, 3 ♀, NMW, cRou, IRSNB): same as holotype, AJB0000529, AJB0000530; same as holotype except, (MBS 81A), 31.V–8.VI.2002, AJB0000531, AJB0000532; same as holotype except, 81D, sifted, 31.V–8.VI.2002, H. Schillhammer & M. Hlaing, AJB0000533. Myanmar: Kayin State: ‘Carin Chebà’, 900–1100 m, V-XII.1888, L. Fea, 1 ♂ AJB0000535 (IRSNB), 1 ♀ AJB0000536 (IRSNB). Shan State: Kalaw, in fungi under decaying log, 19.III.1982, G. de Rougemont, 1 ♂, AJB0000534 (cRou); Taunggyi, decaying wood in waterfall pool, 6.VI.1980, G. de Rougemont, 1 ♀, AJB0000581 (cRou).
Diagnosis
This species may be recognized by the following: head entirely dark; pronotum widest in posterior third; elytra partly dark, discal markings of elytra extending onto epipleuron, not forming v-shape, medial and lateral markings of different sizes and never entirely fused (Fig. 2B, 5G; apex of median lobe not hooked or flattened in lateral view, apical portion with flat ventral face in lateral view (Fig. 14E), broad and short in parameral view (Fig. 14D); paramere with long and elongate apical portion, slightly longer than median lobe (Fig. 14D).
Description
Measurements ♂ (n = 5): HW/HL 1.38–1.45; PW/PL 1.26–1.33; EW/ EL 1.19–1.26; ESut/PL 0.77–0.82; PW/HW 0.99–1.04; forebody length 4.0–4.5 mm.
Measurements ♀ (n = 2): HW/HL 1.39–1.43; PW/PL 1.24–1.30; EW/ EL 1.22–1.24; ESut/PL 0.76–0.80; PW/HW 1.05–1.08; forebody length 4.6–4.9 mm.
Extremely similar to B. pictus and differing only in the following: median lobe in lateral view with apex not hooked, apical portion with ventral face straight (Fig. 14E); median lobe in parameral view with apical portion slightly narrower (Fig. 14D); apical portion of paramere distinctly more elongate and narrower (Fig. 14F).
Distribution
Figure 21B. Bolitogyrus schillhammeri is known from three localities in the Shan Hills (incl. Karen hills) of Myanmar.
Bionomics
This species has been collected in March, May and June at 900–1320 m. Specimens have been collected from rotten wood and from within fungi.
Etymology
The species is named in honor of Harald (Harry) Schillhammer (NMW), the collector of many specimens of the type series, and a wonderful friend and field companion. Harry’s adventurous spirit and broad knowledge have led to many shared ‘eureka’ moments for staphylinid systematics.
Comments
Bolitogyrus schillhammeri is most similar to B. pictus but can be distinguished by the narrower apex of the paramere and the non-hooked apex of the median lobe in lateral view.
