Diagnosis. This species is similar to A. spiculipenis , from which it may be distinguished by the characters given in the key. Males of A. ventrituber .possess tubercles on the basal abdominal ventrite, which are absent in A. spiculipenis . Females may be distinguished by the shape of emargination of the apex of the last abdominal ventrite, which is shallow and scarcely visible in A. ventrituber , but deeper and clearly visible in A. spiculipenis .
Description (Holotype): Body form, color and pubescence as in Fig. 6 View FIGURES 1 – 6 . Head large, distinctly convex; eyes feebly protruding from head outline. Sides of pronotum moderately arcuate, apical pronotal margin slightly narrower than basal margin; anterior pronotal lobe wide, projecting beyond anterior pronotal angles, posterior angles slightly obtuse; pronotal disk markedly convex, feebly impressed at base, without lateral impressions; prehumerus short, extending to basal third of pronotal length, feebly costate, moderately arcuate, with apex distinctly distant from marginal carina (lateral view).
Elytra without humeral carinae, moderately attenuate apically, bichromatic bronze and black-violet patterns combined with monochromatic whitish pubescence; apices narrowly separately angulately-arcuate.
Prosternum ( Fig. 38 View FIGURES 34 – 49 ): Prosternal lobe large, with apical margin deeply incised medially; prosternal process sharply tricuspidate, sides expanded in straight line, disk feebly impressed. Basal abdominal ventrite with obvious, median tubercles in proximal third. Apex of last abdominal ventrite faintly emarginate.
Aedeagus ( Fig. 61 View FIGURES 58 – 76 ).
Length. 3.9–4.4 mm, Holotype 4.1 mm.
Sexual dimorphism. Female without tubercles on basal abdominal ventrite, and with very obsolete emargination at apex of last abdominal ventrite.
Variability. Pronotal sides in some paratypes are less arcuate or almost subparallel in basal two thirds. Elytral pubescence is sometimes slightly bichromatic, combining golden and white hairs.
Type series. Holotype 3 ( EJCB): “ THAI, 18–24.IV.1991, Lansang n. p. 500 m, 16°48'N, 98°57'E, Vít Kubáň leg.” Paratypes (4 exs): 2 Ƥ ( EJCB) with the same locality label; 1 3 ( EJCB): “ Thailand 7–8.V.1992, Huai Sua Tao [near Mae Hong Son], Dembický leg.”; 1 3 ( EJCB): “ Burma, 22–24.vi.1997, N Mandalay division, PWE Kauk falls env. (8 km NE Pyin Oo Lwin), J. Kaláb leg.”. Type locality. Thailand, Lansang national park, 500 m, 16°48'N, 98°57'E.
Distribution. North Thailand, Myanmar (Mandalay).
Etymology. Derived from the Latin words ventral (situated on the lower, abdominal plane of the body) and tuber (a rounded swelling or protuberance; a tuberosity; a tubercle), which refers to the presence of the two tubercles on the basal abdominal ventrite in the male.
