Question: What taxa is Ommatidae part of?

Knowledge 1: 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. Extant species of this group only occur in Australia and South America, but the geographical distribution was much wider during the Mesozoic spanning across modern day Europe, Siberia, Myanmar, and China. Discovery of Upper Jurassic Chinese and Upper Cretaceous Burmese fossils suggest that they were widespread during Pangea. So far, 13 extinct genera containing over 100 species of these beetles have been described. Two extant genera have been assigned to this family: "Omma" and "Tetraphalerus". [SEP] Knowledge 2: Myxophaga
Myxophaga is the second smallest suborder of the Coleoptera after Archostemata, consisting of roughly 65 species of small to minute beetles in four families. The members of this suborder are aquatic and semiaquatic, and feed on algae.

Kabwe 1, also called the Broken Hill skull, was assigned by Arthur Smith Woodward in 1921 as the type specimen for Homo rhodesiensis; most contemporary scientists forego the taxon ``rhodesiensis ''altogether and assign it to Homo heidelbergensis. The cranium was discovered in Mutwe Wa Nsofu Area in a lead and zinc mine in Broken Hill, Northern Rhodesia (now Kabwe, Zambia) on June 17, 1921 by Tom Zwiglaar, a Swiss miner. In addition to the cranium, an upper jaw from another individual, a sacrum, a tibia, and two femur fragments were also found. The skull was dubbed`` Rhodesian Man'' at the time of the find, but is now commonly referred to as the Broken Hill skull or the Kabwe cranium.

[SEP] Knowledge 2: Meridiungulata
Meridiungulata is an extinct clade with the rank of cohort or superorder, containing the South American ungulates Pyrotheria (possibly including Xenungulata), Astrapotheria, Notoungulata and Litopterna. It is not known if it is a natural group; it was erected to distinguish the ungulates of South America from other ungulates. Relationships between the orders inside Meridiungulata remain unresolved and it could well be a "wastebasket taxon". Most Meridiungulata died out following the invasion of South America by North American ungulates and predators during the Great American Interchange, but a few of the largest species of notoungulates and litopterns survived until the end-Pleistocene extinctions.
