Diagnosis. This species is very distinctive by the strikingly contrasting elytra which are black except for the golden-bronze elytral apices covered with dense, golden pubescence. The head and anterior part of pronotum are covered with golden pubescence similar to that on elytral apices.

Description (Holotype): Body form, color and pubescence as in Fig. 18View FIGURES 13 – 18. Head large, frons and vertex feebly convex; eyes markedly protruding from head outline.

Pronotum conspicuously convergent apicad, with sides subparallel in basal third and then strongly, almost rectilinearly convergent to apex; apical pronotal margin distinctly narrower than basal margin; anterior pronotal lobe distinctly projecting beyond anterior pronotal angles; posterior angles rectangular; pronotal disk conspicuously convex, distinctly impressed at base; lateral impressions absent; prehumerus extending to about half of pronotal length, sharply costate, arcuate, with apex strikingly arcuate to pronotal margin but distant from marginal carina (lateral view).

Elytra with feeble and short humeral carinae, bichromatic, black except for golden-bronze apex, combined with white and golden ornamental pubescence; apices separately arcuate.

Prosternum ( Fig. 47View FIGURES 34 – 49): Prosternal lobe large, with apical margin distinctly incised medially; prosternal process sharply tricuspidate, sides obviously, arcuately expanded; disk deeply impressed, with lateral corners distinctly protruding ventrad. Apex of last abdominal ventrite distinctly emarginate.

Aedeagus ( Fig. 67View FIGURES 58 – 76).

Length. Holotype 4.9 mm.

Sexual dimorphism. Female unknown.

Variability. Unknown.

Type series. Holotype 3 ( EJCB): “LAO-N, Phongsaly prov., 21 ° 41 '– 2 'N, 102 °06'–08'E, Phongsaly env., 28.v.– 20.vi. 2003, 1500 m, P. Pacholátko leg.”. Type locality. north Laos, Phongsaly province, Phongsaly env., 1500 m, 21 ° 41 '- 2 'N, 102 °06'-08'E.

Distribution. North Laos (Phongsali).

Etymology. The name is derived from the Latin noun apex, -icis (a combining shape of apex or apical) and aureus (golden) to stress the strikingly golden elytral apices of this species.

Diagnosis. This species ( Figs. 19–21View FIGURES 19 – 24) is distinctive by its strikingly bichromatic elytra with the dark violet and golden-bronze, or golden-green pattern; pronotal sides subparallel or feebly arcuate except for the conspicuously arcuate anterior part; apical pronotal margin narrower than basal margin; anterior pronotal lobe wide, slightly projecting beyond anterior pronotal angles; pronotal disk conspicuously convex; prehumerus feebly costate, moderately arcuate, with apex distinctly distant from marginal carina (lateral view); prosternal lobe arcuately or subangulately emarginate; prosternal process ( Fig. 48View FIGURES 34 – 49) tricuspidate with sides expanded in straight line and weakly impressed. Apex of last abdominal ventrite with distinct emargination. Aedeagus as in Fig. 68View FIGURES 58 – 76.

Length. 3.5–4.9 mm.

Distribution. China: Shaanxi, Sichuan, Yunnan; India: Assam, Meghalaya, Tamil Nadu, Uttar Pradesh, West Bengal (paratype of A. komiyai  ); Laos: Borikhamxai, Louang Namtha, Louangphrabang, Phongsali, Vientiane; Myanmar: Shan State; Nepal; Sri Lanka; Thailand: Chiang Mai, Kanchanaburi, Loei, Mae Hong Son, Nan, Tak; Vietnam.

Remarks. Agrilus muscarius  is the most common and most widely distributed species of the A. muscarius  species-group. Baudon (1968) reported the capture of this species from foliage of Indigofera galegoides  ( Fabaceae  ). Based on the altitude data from locality labels of the examined specimens, this species was collected at altitude range between 500 m ( Laos) and 2528 m ( China: Yunnan).

Agrilus semicaducus Jendek  , sp. nov. Figs. 22 –23View FIGURES 19 – 24, 49View FIGURES 34 – 49, 69View FIGURES 58 – 76

Diagnosis. This species is similar to A. muscarius  in general appearance, but it differs mainly by the larger, more prolonged body, the longer elytral apex and by the trapezoid pronotum.

Description (Holotype): Body form, color and pubescence as in Fig. 22View FIGURES 19 – 24. Head moderately convex; eyes flat, not protruding from head outline.

Pronotum distinctly convergent apicad, sides subparallel in basal third and then obviously, subrectilinearly convergent to apex; apical pronotal margin distinctly narrower than basal margin; anterior pronotal lobe faint, not projecting beyond apical pronotal angles; posterior angles obtusely rectangular; pronotal disk obviously convex, with distinct prescutellar impression; lateral impressions absent; prehumerus extending to about half of the pronotal length, sharply costate, arcuate, subparallel with marginal carina (lateral view).

Elytra without humeral carinae, brightly bichromatic with golden and dark-violet patterns combined with whitish and golden ornamental pubescence; apices separately, shallowly arcuate.

Prosternum ( Fig. 49View FIGURES 34 – 49): Prosternal lobe large, with apical margin arcuately emarginate; prosternal process with subparallel sides, disk impressed, lateral corners protruding ventrad. Basal abdominal ventrite without tubercles; apex of last abdominal ventrite slightly emarginate.

Aedeagus ( Fig. 69View FIGURES 58 – 76).

Length. 4.0– 4.9 mm, Holotype 4.9 mm.

Sexual dimorphism. Female without apparent sexual differences.

Variability. Pronotal sides in basal third are sometimes divergent. Elytral pubescence in paratypes from the locality “Ban Saluei” is present also on humeral part ( Fig. 23View FIGURES 19 – 24).

Type series. Holotype 3 ( EJCB): “ Laos north, 13–24.V.1997, 15 km NW Louang Namtha, N 21 °07.5, E 101 °21.0, alt. 750 ± 100 m, E. Jendek & O. Šauša leg.”. Paratypes 7 exs: 2 Ƥ ( EJCB): with the same locality label as holotype; 2 3, 3 Ƥ ( EJCB): “LAOS-NE, Houa Phan prov., 20 ° 12-13.5 'N, 103 ° 59 '. 5- 104 °01'E, Ban Saluei ⊣ Phou Pane Mt., 1340–1870m, 15.iv.– 15.v. 2008, Lao collectors leg.” Type locality. Laos north, 15 km NW Louang Namtha, N 21 °07.5, E 101 °21.0, alt. 750 ± 100 m.

Distribution. north Laos: Louang Namtha, Houa Phan.

Etymology. The name is derived from the prefix semi - (Latin, partially, incompletely, somewhat) and caducus (Latin, subject to shedding), to indicate the variability in the extent of elytral pubescence ( Figs. 22–23View FIGURES 19 – 24).
