C o m m e n t: Stilicoderus denticulatus was previously known exclusively from the type locality in the Laobie Shan, southern Yunnan, China. The above material is distinguished from the type material by the slightly shorter apical portion of the ventral process and the slightly shorter apical sclerotized structures of the aedeagus. Since no additional differences were found, these differences are attributed to intra- rather than interspecific variation. Remarkably, the species was not found during a recent field trip to southeastern Yunnan, the region between the type locality and North Vietnam.
