REMARKS. The description of Plateros elisus Pic, 1921 can be found only in the identification key to Plateros species in a paper entitled ‘Contribution à l´étude des Lycides’ [ Pic, 1921]. With the relevant theses referred to, the species’ description would read as follows: ‘Allongé, prothorax roux avec une bande discale noire étranglée au milieu, rétréci et subanguleux en avant, angles postérieurs plus ou moins saillant en dehors; élytres noires. Long. 7 mill. Tonkin.’ The difference between P. elisus and P. chinensis (described in the same paper, i.e., in the same identification key, as P. formosanus ) seems to be limited to the elongate body (´allongé´) in elisus vs. not quite elongate or broad body (´peu allongé ou assez large´) in chinensis . The type specimen of P. elisus has not been found in MNHN, where the Pic collection is housed. Nevertheless, as in the widespread and fairly variable P. chinensis both relatively broad and narrow body forms may be encountered, it seems plausible to attribute both taxa to a single species, which allows proposing new synonymy, i.e., Plateros elisus Pic, 1921 , syn.n. a new younger synonym of Plateros chinensis Waterhouse, 1879 .

The description of Plateros annamitus Pic, 1921 can also be found only in the same identification key [ Pic, 1921]. The compiled description would read as follows: ‘Assez large, prothorax roux à bande médiane noire complète, assez régulièrement arqué en avant, angles postérieurs plus ou moins saillant en dehors; élytres noires, subparallèles. Long. 7 mill. Annam.’ The type specimen of P. annamitus has not been found in MNHN, where the Pic collection is housed. Nevertheless, as this description could be referred to the same Plateros chinensis and as no other species of this coloration pattern have been detected in the region, it would seem plausible to conclude that both taxa belong to a single species, which allows suggesting that Plateros annamitus Pic, 1921 , syn.n. is another new younger synonym of Plateros chinensis Waterhouse, 1879 .
