Comments. The species Cassolus sumatranus Lansberge, 1885 was originally placed in the genus Cassolus . Its overall similarity with the species of Panelus was first noticed by Boucomont (1914). The examination of the type series revealed that this species shares the diagnostic characters of the representatives from the genus Panelus subgenus Macropanelus . These characters are the asymmetrical shape of aedeagus, structure of endophallic sclerites, and the striation of elytra (some of them are provided in Fig. 3 ). Given this evidence, I transfer Cassolus sumatranus to Panelus . The formal inclusion of this species in the phylogenetic analysis was beyond the scope of present work since morphological characters unambiguously identify the taxonomic position of this species in Panelus .
