Distribution. Indonesia; Malaysia; Thailand (new record). More information on distribution can be found in Qiu et al. (2015).

Remarks. The white tomentose maculae on the elytron of Platysodes verlorenii are fairly varying in number and size ( Figs. 18–22 ). Apart from the specimens bearing two or three maculae on elytron mentioned in Qiu et al. (2015), elytron with a single macula also can be observed in a few individuals ( Fig. 18 ), even the maculae are entirely absent ( Fig. 19 ). Our re-examination confirmed that the totally black female of P. verlorenii from southern Thailand has been misidentified as P. jansoni by Sakai (2001) and Qiu et al. (2015) since their appearances are rather similar. Moreover, Qiu et al. (2015) noticed the presence of matt area in the elytral distal declivity of P. ver-lorenii ( Figs. 22–23 ); nevertheless, they suspected that this species is conspecific to P. jansoni and P. formosanus . The examination of further materials shows this character is stable for P. verlorenii which lets it distinctly different from the latter two. Conversely, this species resembles P. sabatinellii new species in elytron with white maculae and matt distal declivity ( Figs. 3 , 22 ). By the number of grooves on elytron, they can be readily differentiated.
