Notes. Habitus and male genitalia are given in Figs 2C–D View FIGURE 2 , 3A View FIGURE 3 and 6E–I View FIGURE 6 .

Collection details. In Zhejiang, the specimens were collected together with P. gemellatus among decaying leaves in a stream within the Gutianshan Nature Reserve ( Fig. 8B View FIGURE 8 ) and in a puddle at the bottom of a rock wall covered with a film of seeping water, near Tianpu Village ( Fig. 8C View FIGURE 8 ).

Distribution. Central and southeastern China (Anhui, Fujian, Guangdong, Guizhou, Guangxi, Hunan, Jiangxi, Shaanxi, Shanxi, Zhejiang) ( Fig. 10B View FIGURE 10 ). First record from Guangxi Zhuang Autonomous Region.

Notes. Platynectes dissimilis exhibits highly variable elytral pattern. Examined specimens of P. dissimilis from Zhejiang and Sanqingshan Mt. (Jiangxi) had the elytral yellow vittae absent from the basal third of the elytra ( Fig. 3A View FIGURE 3 ), two specimens from Shaanxi and a single specimen from Anhua County (Hunan) had the elytral yellow vittae indistinct only basally ( Fig. 2D View FIGURE 2 ), whereas other specimens examined from south China were fully coloured ( Fig. 2C View FIGURE 2 ). Since specimens we checked from southern areas (Guangdong, Guangxi and south Hunan) are more fully coloured, this variation might be related to temperature .
