Diagnosis. This species is very distinctive by the bell-shaped pronotum with acute basal angles and by the aedeagus conspicuously expanded apically.
Description (Holotype): Body form, color and pubescence as in Fig. 30 View FIGURES 25 – 30 . Head small, moderately convex; eyes not protruding from head outline. Pronotum bell-shaped, with sides slightly bisinuate, emarginate at base and then arcuately convergent apicad; apical pronotal margin distinctly narrower than basal margin; anterior pronotal lobe large and distinctly projecting beyond apical pronotal angles; basal angles acute; pronotal disk obviously convex, with distinct basal impression; lateral impressions absent; prehumerus extending to about half of pronotal length, sharply costate, feebly arcuate, with apex clearly distant from marginal carina (lateral view).
Elytra elongate, without humeral carinae, faintly bichromatic, with golden-bronze and golden-violet patterns, combined with golden and golden-whitish ornamental pubescence; apices widely, separately, shallowly arcuate.
Prosternum ( Fig. 54 View FIGURES 50 – 57 ): Prosternal lobe large, with apical margin distinctly incised medially; prosternal process with faintly expanded sides; disk flat with uniplanar lateral corners. Basal abdominal ventrite without tubercles; apex of last abdominal ventrite slightly, but distinctly emarginate.
Aedeagus ( Fig. 73 View FIGURES 58 – 76 ).
Length. 4.8–5.7 mm, Holotype 5.7 mm.
Sexual dimorphism. Female without apparent sexual differences.
Variability. Some paratypes have basal pronotal impression deeper; elytra more contrastly bichromatic and elytral apices more markedly arcuate.

Type locality. Thailand borealis, Chiang Mai province, Chiang Dao [19°24'N, 98°55'E] Distribution. Thailand: Chiang Mai, Mae Hong Son.
Etymology. The name is a combination of Latin verb dilato, -are (to make wider or larger, cause to expand) and the noun penis (the male organ of copulation), to stress the peculiar shape of the aedeagus of this species.
