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 narrow, almost without expansion (Fig. 4G).
Redescription
Measurements ♂ (n = 3): HW/HL 1.34–1.42; PW/PL 1.26–1.29; EW/ EL 1.15–1.16; ESut/PL 0.83–0.85; PW/HW 0.98–1.0; forebody length 5.1–5.4 mm.
Measurements ♀ (n = 3): HW/HL 1.34–1.38; PW/PL 1.11–1.15; EW/ EL 1.12–1.17; ESut/PL 0.75–0.80; PW/HW 0.95–1.03; forebody length 5.3–5.8 mm.
Coloration: head, pronotum and abdomen entirely dark; elytra with pale yellow, raised markings, inner marking oval shaped and larger than outer circular marking; antennomeres 1-3 dark brown, 4-5 reddish, 6-10 dark brown, 11 distinctly paler, light brown to yellowish; palpi dark brown, apical segment paler; legs yellow, forecoxae dark brown, femur with dark band in apical half, tibia entirely dark with ventral face sometimes paler.
Head distinctly transverse; dorsal surface with moderately dense, clearly separated asetose punctures, frons with only scattered punctures and poorly impressed. Antennomere 6 slightly, 7-10 distinctly transverse and more or less symmetrical.
Pronotum distinctly (males) to slightly transverse, about as wide as head, with shallow micropunctures scattered on disc, becoming more distinct on anterior angles. Elytra slightly transverse, suture slightly to distinctly shorter than pronotum at middle.
Abdomen with disc of tergites III-VI distinctly and broadly impunctate; sternites III-IV with basal line distinctly projected posteriad at middle.
Median lobe in lateral view with apical portion projected ventrad, apex deflexed dorsad (Fig. 12I); median lobe in parameral view with basal teeth appearing at lateral margins (Fig. 12H); paramere shorter than median lobe, bilobed, lobes narrowly separated and slightly convergent (Fig. 12J); peg setae occurring in long group on each lobe from apex to just apicad of emargination (Fig. 12J); male sternite VIII with extremely shallow emargination and triangular glabrous area medially; male sternite IX moderately expanded at midlength, with distinct U-shaped emargination.
Female with tergite VIII entire (female paratype) to emarginate, emargination minute to small; tergite X elongate shield-shaped, with broadly rounded apex, disc slightly raised and without depressions or strong ridges.
Distribution
Figure 20D. Endemic to the Western Ghats of India.
Bionomics
Bolitogyrus lasti has been collected at 1000-1200 m during January, May, September and December.
Comments
Bolitogyrus lasti is most similar externally to B. ornatipennis from Java but can be distinguished by the narrow pronotal expansion and more circular inner pale elytral spot.
