Permotanyderus [SEP] parent taxon
Permotanyderus
Permotanyderus is an extinct genus of protodipteran insect of the Permotanyderidae family, first described by Edgar F. Riek in Australia in 1953 and which contains a single species "P. ableptus".
Evidence of the presence of Diptera or their direct predecessors in the Upper Permian of Australia is shown by the presence of Mecoptera in those formations. The Paratrichoptera of the Upper Permian probably, and those of the Triassic certainly, have been considered survivors of the maternal group. Riek described in 1953 two species of protodipteran of the Upper Permian
Taxon in disguise
In bacteriology, a taxon in disguise is a species, genus or higher unit of biological classification whose evolutionary history reveals has evolved from another unit of similar or lower rank, making the parent unit paraphyletic. This happens when rapid evolution makes a new species appear radically different from the ancestral group, so that it is not (initially) recognised as belonging to the parent phylogenetic group, leaving the latter an evolutionary grade.
While the term is from bacteriology, parallel examples are found throughout the tree of
