(Figs 12–19)  
 Description. Male (Figs 12–15). Integument mostly black with violaceous reflections; ventral side of antennae brown, partially with violaceous reflections; elytra yellowish brown; femora reddish brown with slightly distinct violaceous reflections; tibiae narrowly violaceous on base (more distinctly in metatibiae), with remaining surface reddish-brown; tarsomeres I–II reddish-brown; tarsomeres III–IV from dark reddish-brown to brown; tarsomere V reddish-brown except distal area slightly violaceous.   
 Head. Frons, vertex, and antennal tubercles finely, densely, confluently punctate (punctures finer from middle of frons); frons and area between antennal tubercles with abundant, long, erect, dark-brown setae (more reddishbrown depending on light intensity); area between upper eye lobes with minute, sparse, reddish-brown setae interspersed with sparse, long, erect, brown setae; remaining surface of vertex with abundant, long, erect, darkbrown setae. Area behind upper eye lobes smooth, glabrous on small area close to eye, finely, abundantly punctate, with abundant, erect, long, dark-brown setae on remaining surface. Area behind lower eye lobes finely, densely punctate (punctures slightly finer than on vertex); with abundant, long, erect, dark-brown setae. Genae finely, abundantly punctate toward ventral side, smooth toward clypeus; with moderately abundant, long, erect, darkbrown setae on punctate area, glabrous on smooth area. Gulamentum slightly depressed between eyes; finely, densely punctate throughout, somewhat rugose toward prothorax; with abundant, long, erect, dark-brown setae. Distance between upper eye lobes 0.73 times length of scape; in frontal view, distance between lower eye lobes 1.47 times length of scape; in ventral view, distance between lower eye lobes 1.67 times length of scape. Antennae 1.64 times elytral length, reaching elytral apex at apex of antennomere X. Scape finely, confluently punctate on outer surface, finer sparser dorsally and on inner surface, slightly coarse, shallow, sparse ventrally; with moderately short, decumbent, reddish-brown setae dorsally, interspersed with erect setae on basal third; with long, erect, darkbrown setae ventrally. Antennomere III finely, sparsely punctate dorsally on basal 2/3, striate-punctate on distal third; remaining antennomeres entirely striate-punctate dorsally. Antennal formula (ratio) based on length of antennomere III (not including projection of V–X): scape = 0.43; pedicel = 0.08; IV = 0.54; V = 0.43; VI = 0.43; VII = 0.40; VIII = 0.37; IX = 0.37; X = 0.37; XI = 0.60; XII = 0.40.   
 Thorax. Prothorax 2.0 times wider than long. Pronotum with large gibbosity on each side of posterior 2/3, and small central gibbosity near posterior margin; moderately finely, densely punctate throughout, punctures finer toward posterior margin centrally, confluent, becoming the surface slightly rugose laterally; with abundant, long, erect, dark setae laterally, gradually sparser toward central area. Prosternum finely, densely punctate; with abundant, long, erect, dark setae. Prosternal process 2.5 times wider than prosternal length, 1.4 times wider than maximum width of profemora; with reddish-brown pubescence interspersed with abundant reddish-brown setae. Metaventrite minutely, moderately abundant punctate laterally; with abundant, long, erect, dark-brown setae close to metanepisternum, gradually sparser toward central plate; central plate with abundant, reddish-brown pubescence interspersed with long, erect setae of same color. Scutellum moderately coarsely, densely punctate (punctures coarser than on pronotum); with long, erect, sparse, yellowish-brown setae. Elytra. Moderately finely, densely punctate-reticulate throughout; with long, suberect, sparse, yellowish-white setae along suture and epipleura (longer, more abundant on basal third, especially along epipleura). Legs. Femora with moderately finely, sparse, somewhat scabrous punctures. Tibiae slightly and shallowly scabrous.   
 Abdomen. Ventrites I–IV finely, sparsely punctate except coarser and denser punctures close to distal margin (especially centrally); ventrite V finely, sparsely punctate except coarser and denser punctures laterally and close to distal margin.   
 Female (Figs 16–19). Head reddish brown except black area close to prothorax and behind upper eye lobes, dark reddish-brown area behind most surface of lower eye lobes, and yellowish-brown posterior area of gulamentum; mouthparts reddish brown, with apex of palpomeres yellowish brown; scape, pedicel and antennomeres III–VIII reddish-brown; antennomeres IX–XI gradually dark; mandibles reddish brown, becoming black toward apex. Pronotum reddish brown with transverse, large black band centrally. Prosternum black laterally, reddish-brown centrally; prosternal process reddish brown except black lateral band on each side of basal half. Ventral side of meso- and metathorax black (central area of metaventrite slightly reddish depending on light intensity). Scutellum black. Elytra black entirely margined with yellow band. Legs reddish brown (femora slightly lighter basally). Abdominal ventrites I–III dark brown laterally (except narrow, yellowish posterior margin and almost black area close to lateral margin), yellowish-brown centrally (more reddish-brown on III); abdominal ventrite IV dark brown (slightly reddish centrally depending on light intensity) except yellowish small centrobasal area and narrow area close to distal margin; abdominal ventrite V yellowish brown on centrobasal area, dark brown on remaining basal half, dark reddish-brown on distal half. Antennae 1.04 times elytral length; antennal formula (ratio) based on length of antennomere III (not including projection of V–X): scape = 0.31; pedicel = 0.05; IV = 0.57; V = 0.47; VI = 0.38; VII = 0.35; VIII = 0.28; IX = 0.27; X = 0.25; XI = 0.47.   
 Dimensions (holotype male/ paratype female). Total length, 18.00/21.70; prothoracic length, 2.40/2.30; posterior prothoracic width, 4.50/4.70; anterior prothoracic width, 3.80/3.55; maximum prothoracic width, 4.90/ 4.70; humeral width, 7.00/7.50; elytral length, 11.60/15.50.   
 Type material. Holotype male (figures 12–15; MZSP), paratype female (figures 16–19; CZCP), from VENEZUELA, Merida: Apartaderos vill. env. (Mucubaí National Park; 3500 m), 13.IV.2003, J. Vondráček col.   
 Etymology. The name of this species was given to the memory of the late Mr. Nobuhiko Katsura who died about a year ago. When he was alive, he was an eminent collector of coleopterous insects and a valued friend of the second author to whom he provided the specimens of this new species.
