Capetoxotus rugosus Tippmann, 1959 belongs to the tribe Apatophyseini (sf. Dorcasominae). However, this may be a junior synonym of Aristogitus cylindricus Thomson, 1860 which traditionally has been attributed to Aphanasiini (sf. Cerambycinae). (cf. e.g. Peter Svacha & Lawrence 2014 Handbook of Zoology, Coleoptera vol. 3 p. 143 which is accessible on the Internet).
