Other material
LAOS: Oudomxay: Ban Nam Mo, 3.IV.1918, R.V. de Salvaza, 1 ♂, AJB0000504 (BMNH); Phongsali: Phongsali env., 1300-1500 m, 1-15.V.2004, Lao, 1 ♂, AJB0000390 (cShi). Country unknown: 1 ♂ (BMNH) [labels lost].
Diagnosis
Within the Carnifex Group: elytral disc entirely reddish (Fig. 1F); abdominal tergites III-V with relatively narrow dark markings at middle (Fig. 5B); peg setae arranged in both marginal and medial groups (Fig. 11L); basal teeth of median lobe placed medially in parameral view (Fig. 11J); apex of median lobe in parameral view evenly narrowed to apex (Fig. 11J).
Redescription
Measurements ♂ (n = 4): HW/HL 1.38–1.45; PW/PL 1.31–1.41; EW/ EL 1.18–1.27; ESut/PL 0.77–0.80; PW/HW 1.08–1.14; forebody length 6.3–7.9 mm.
Measurements ♀ (n = 1): HW/HL 1.38; PW/PL 1.44; EW/ EL 1.25; ESut/PL 0.83; PW/HW 1.14; forebody length 7.3 mm.
Extremely similar to B. carnifex and differing only in the following: dark medial area on pronotum varying from similar to B. carnifex to distinctly larger; lateral face of midfemur with distinct dark band (Fig. 5D); pronotum slightly wider relative to head; median lobe in parameral view almost evenly converging to smaller apex (Fig. 11J), in lateral view, slightly more strongly constricted after basal tooth, which is distinct and appearing at ventral face (Fig. 11K); apex of median lobe in lateral view with median tooth arising from carina, apical portion only slightly deflexed ventrad (Fig. 11K); median lobe in parameral view with apical portion evenly converging to narrower apex, without pair of subapical teeth, basal teeth appearing medially (Fig. 11J); paramere with narrower and more elongate apical portion, basal constriction narrower (Fig. 11L); peg setae with marginal and medial groups more approximate and linear (Fig. 11L); female tergite VIII with narrow and deep emargination; female tergite X with obtuse but pointed apex, disc with pair of raised carinae in apical half, carinae not forming lateral margins of disc.
Distribution
Figure 20B. Distributed in southern Yunnan, China and northern Laos.
Bionomics
Specimens have been collected in January, April and May at elevations ranging from 810-1500 m.
Comments
Bolitogyrus elegantulus is most similar to allopatric B. phukhieo from central Thailand but can be distinguished by the evenly converging apex of the median lobe in parameral view and the differently shaped paramere.
