Diagnosis. P. marmoreus and P. papilionaceus belong to a conspicuous but rarely collected species of notable size.
The Hainan species was described by Ma (1990) as Par- atrichius papilionaceus , based on a single holotype male. Subsequently two males and one female were collected (see list above) allowing a more accurate study of the tax- on. Comparing these types and specimens with Paratrichi- us marmoreus (Moser, 1902) – see list above – we found that the parameres are of identical shape, thus P. papilion- aceus Ma, 1990 must be considered a new junior synonym of Paratrichius marmoreus (Moser, 1902) (n. syn.), but it is remarkable that there are a few differences, mainly in the colour of the integument between the Vietnamese and Hainan’s specimens:
- while the Vietnamese males exhibit a fulvous clypeus, sometimes this colour reduced to the anterior part, the males from Hainan have a completely black clypeus ( Figs 2E View Fig and 3A View Fig )
- similarly, the males inhabiting Vietnam have a long narrow longitudinal fulvous spot in the posterior quarter of the fourth interstriae of the elytron and more-or-less conspicuous fulvous integument under the anterior chalky spots, while the males from Hainan have completely black elytra ( Figs 2A View Fig and 3A View Fig ).
- the females are completely black but have different
shaped chalky spots in the anterior third of the elytron
( Figs 2H View Fig and 3D View Fig ). The females inhabiting the continent
show a constant chalky pattern on the elytron, but it
may be yellowish or whitish.
The above reported morphological/chromatic differences among the insular (Hainan) and continental (N Vietnam) populations of Paratrichius marmoreus suggest that their level of genetic differentiation (if any) should be estimated by molecular methods as soon as possible.
