Lo leg. // Platysodes formosanus H. Kobayashi, 1989, det. K. Sakai, 2013. Distribution. China: Guangdong (new record), Taiwan. Remarks. Platysodes formosanus is extremely similar to P. jansoni and the parameres of both also show no differences (Figs. 12, 17), and that resulted in Qiu et al. (2015) presumed them as the same species. Traditionally, the former is characterized by elytron bearing one tomentose macula and restricted to Taiwan Island (Kobayashi 1990; Qiu et al. 2015), while the latter is totally black and distributed in eastern India and Indochina (Arrow 1910; Qiu et al. 2015). However, we recently obtained a female whose appearance perfectly matches the characteristics of P. formosanus (Fig. 9), but it originated from Guangzhou (Guangdong, China) where located on the southeastern edge of the Asian continent and between the Indochinese Peninsula and Taiwan Island (Fig. 28). Furthermore, an individual of P. formosanus bearing an indistinct macula on elytron (nearly disappeared) was found from Taiwan (Fig. 25), and a female of P. jansoni with two maculae was discovered from Vietnam (Fig. 13). The two specimens have here verified the prediction proposed by Qiu et al. (2015) that the variability of tomentose maculae on elytron can be observed in a species of wide distribution. Therefore, neither endemism of P. formosanus nor morphological differences between the two species are well established, but we would like to formally propose the synonymy when sufficient material got rather than synonymize them at present.
