Archostemata genera

Adinolepis is a genus of beetles in the family Cupedidae containing four species, all endemic to Australia. A fifth species, Adinolepis scalena, was transferred to Ascioplaga in 2009.

Ascioplaga is a genus of beetles in the family Cupedidae, one of the six extant families within the Archostemata beetle group. The genus contains two species endemic to New Caledonia and one described from northern Queensland in Australia.

Prolixocupes is a genus of beetles in the family Cupedidae. It contains two species, P. latreillei and P. lobiceps. The former is endemic to central Chile and adjacent areas of western Argentina between 25° and 35° S, while the latter is endemic to Arizona and California in Western North America.

Rhipsideigma is a genus of beetles in the family Cupedidae. It contains five species, four of which ( R. lugubris (Fairmaire, 1895), R. raffrayi (Fairmaire, 1884), R. adjuncta Neboiss, 1984 and R. anosibense Neboiss, 1989) are endemic to Madagascar, the other (R. cretaceotincta (Kolbe, 1897)) being endemic to the northern coast of Tanzania. They vary in length from 13 mm to 20 mm, and are up to 6 mm wide.

Paracupes is a genus of beetles in the family Cupedidae, the reticulated beetles.

Omma is a genus of beetles in the family Ommatidae. Omma is an example of a living fossil. The oldest species known, O. liassicum, lived during the final stage of the Triassic (Rhaetian), over 200 million years ago, though the placement of this species in Omma has been questioned. Numerous other fossil species are known from the Jurassic and Cretaceous of Europe and Asia. The only living species is Omma stanleyi, which is endemic to Australia. Three other extant species endemic to Australia that were formerly part of this genus were moved to the separate genus Beutelius in 2020. Omma stanleyi

Priacma is a genus of beetles in the family Cupedidae. It contains a single extant species, Priacma serrata native to western North America and one fossil species, P. megapuncta from the Cenomanian aged Burmese amber. Species previously assigned to the genus from the Yixian Formation of China have been subsequently placed in the separate genus Apriacma.

Tetraphalerus is a genus of beetles in the family Ommatidae, It is currently known from two extant species native to South America and several fossil species from the Jurassic and Cretaceous of Asia.

Beutelius is a small genus of ommatid beetles native to Australia. It is only one of three extant genera in the family, alongside Tetraphalerus and Omma. It currently contains four species, three of which were originally assigned to Omma, and it is distinguished from Omma by the presence of flattened, ribbed scales covering most areas, as well as longer maxillary and labial palps, and an anteriorly depressed gulamentum.
