, for example, are today generally held to include a number of these tribes, and are even sometimes merged into the Colydiini. The tribes are: * Acropini * Adimerini * Colydiini Billberg, 1820 * Gempylodini * Nematidiini * Orthocerini Blanchard, 1845 (= Sarrotriini Billberg, 1820 ( nom. rej.)) * Rhagoderini * Rhopalocerini *

Erichson, 1845 (sometimes in Colydiini) Delimitation of the Colydiinae against the other lineages of Zopheridae is usually unproblematic. The only significant case of dispute may be the Pycnomerini, which is a small lineage of Zopheridae ''incertae sedis'' and was formerly considered an independent family like the "Colydiidae". That treatment is almost certainly wrong, but whether these beetles should be placed in Zopheridae as an additional subfamily Pycnomerinae, or treated as tribe Pycnomerini – and if the latter, whether they are better included in the Colydiinae or the Zopherinae – is still disputed.

Other authors consider the latter ''incertae sedis'' among the Tenebrionoidea; for the former two, see #Systematics and taxonomy, above. The species ''Xylolaemus sakhnovi'' was described in 2014 from a fossil preserved in Baltic amber, which dates to the Middle Eocene. This was the first species of ''Xylolaemus'' described from the fossil record. The extinct genus ''Paleoendeitoma,'' belonging to the extant tribe Synchitini is known from the Cenomanian aged Burmese amber of Myanmar.
