 General distribution: Negros isl., Philippines.   
 Description. Body black, except for yellow-red pronotum and two spots at base of elytra. Body elongated, narrow, dorsal surface of elytra flattened, with coarse and dense punctation, wrinkles, without metallic reflection. Length: 7.6- 8.1 mm, maximal width: 1.8–2.1 mm; length/width ratio: 3.9–4.2.   
Head flattened, with square frontal part and convex, bilobate eyes. Dorsal surface of head with very coarse punctation. Impressed longitudinal line between extended antennal bases indistinct between coarse punctures. Labrum dark-brown, slightly pubescent, shiny. Clypeus dark-brown, almost invisible, shiny. Mandibles brown, with darker apex, sharp, massive, wide, shiny, relatively short, with sparse short lateral pubescence. Cheeks with very sparse, short, grey pubescence. Antennae slender. Male antennae nearly exceeding apex of elytra. Female antennae shorter, reaching slightly behind middle of elytra. Antennomeres covered with coarse punctures and fine, sparse pubescen ce; an ten n omeres 1– 5 sligh tly thickened apically, black.  
Pronotum yellow-red, cylindrical, elongated, slightly narrowed in apical and basal portions. Surface with dense and coarse punctation and short wrinkles. Pronotum of female yellow-red, on dorsal disc with two elongated,, curved spots.  
 Scutellum small, black, with slightly rounded apex. Pars stridens almost completely covered with pronotum.   
Elytra almost parallel-sided, black, basal margin with yellow-red, misty spot (female with very small, rudimentary spots), from middle slightly widened apically, flattened, with indistinct raised shoulders hump. Elytra shiny, without metallic reflection. Punctation very dense, not arranged in longitudinal rows. Apical margin of elytra with two sharp extensions: one smaller near suture and one large latero-apical extension, r with very sharp apex..  
Ventral surface of body covered with grey pubescence. Legs black, covered with very fine pubescence, inner margin of tibia with dense pubescence.  
 Differential diagnosis. It differs from all remaining species of the genus by the presence of round yellow-red spot at each basal margin of the monochrome black elytron.   
 Etymology. This species is named after my friend and colleague Andris Bukejs (Daugavpils, Latvia) in appreciation of cooperation, and in gratitude for his contribution to the studies of fossil Coleoptera.
