Ommatidae
The Ommatidae are a family of beetles in the suborder Archostemata. The Ommatidae are considered the extant beetle family that has most ancestral characteristics. There are only seven extant species, confined to Australia and South America. However, the geographical distribution was much wider during the Mesozoic spanning across Eurasia and Australia, suggesting that they were widespread on Pangea. So far, over 26 extinct genera containing over 170 species of these beetles have been described. Three extant genera have been assigned to this family: ''Omma,'' '' Tetraphalerus'' and '' Beutelius''. The family is considered to be a subfamily of Cupedidae by some authors, but have been found to be more closely related to Micromalthidae in molecular phylogenies. A close relationship with Micromalthidae is supported by several morphological characters, including those of the mandibles and male genitalia. Due to their rarity, their ecology is obscure, it is likely that their larvae feed ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Omma
''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'' is strongly associated with wood, being found under ''Eucalyptus'' bark and exhibiting Apparent death, thanatosis when disturbed. Its larval stage and many other life details are unknown due to its rarity. Males are typically 14–20 mm in length, while females are 14.4-27.5 mm. ''Omma stanleyi'' occurs throughout eastern Australia from Victoria (Austr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Burmocoleus
''Burmocoelus'' is an extinct genus of Archostematan beetle belonging to the family Ommatidae. It is known from two species, ''Burmocoleus zhiyuani,'' which was initially assigned to the genus ''Brochocoleus'' this was placed into the new genus ''Burmocoleus'' by Kirejtshuk, 2020, who also described a new species, ''Burmocoleus prisnyi.'' Both species are known from the Cenomanian aged Burmese amber from Myanmar. Similar to '' Stegocoleus'', ''Brochocoleus'' and '' Jarzembowskiops'' it has flat, wide elytral edges, but can be distinguished from these genera in several characters, and is more similar to other ommatids in the characters of the prothorax The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on ea ....
