Nothroid Mites - Parvorder: Nothrina
|
The Parvorder: Nothrina contains a single superfamily which itself contains between 4 and 12 families depending on your source. 'iNaturalist' lists 12 families, the 'Encyclopedia of Life' lists 4. Other sources may list 5 or 6 and, to further convolute the matter, the names of the families do not always correspond either. Granted, 'iNaturalist' did apply some taxonomic changes after the last update on the 'Encyclopedia of Life' took place and some sources regard some family names as synonymous with others but, this does not fully explain the ambiguity around this issue. It will require some serious detective work to get to the bottom it all and the outcome may even shed some light on the validity of the name Nothrina itself. Some sources use Holosomata as the parent of that one superfamily and its subdivisions.

The Nothrina, as mentioned, contains a single superfamily, the Crotonioidea. Considering the ambiguity about which family belongs within this superfamily and which does not, the total number of described species is not known but it is at least 700 and probably closer to 900. Of these, only a smattering have been identified locally so far.
The fossil record of the Nothrina goes back some 105 My to the Early Cretaceous. A single fossil of that age was found in north-eastern Spain and identified as belonging to the Genus: Trhypochthonius (Fam: Trhypochthoniidae). Other, more recent fossils at about 38 - 34 My old were found in the Baltic area. Here in Australia, no fossils have been found to date but the Genus: Crotonia (Fam: Cortoniidae) is considered a Gondwanan relict. |
