Classification: ntax_mesozoic -> Eiffellithales -> Chiastozygaceae -> Staurolithites -> Staurolithites mielnicensis
Sister taxa: << < S. handleyi, S. laffittei, S. dorfii, S. lumina ⟩⟨ S. imbricatus, S. dicandidula, S. mitcheneri ⟩⟨ S. angustus, S. mutterlosei, S. zoensis ⟩⟨ S. aachenus, S. aenigma, S. ellipticus, S. elongatus, S. integer, S. mielnicensis, S. parma, S. sp.

Distinguishing features: Bicyclic species with narrow rim, triangular feet to the crossbars give the species a distinctive LM appearance.


Taxonomy:

Citation: Staurolithites mielnicensis (Górka, 1957) Perch-Nielsen, 1968 sensu Crux 1982
Rank: Species
Basionym: Discolithus mielnicensis Górka, 1957
Synonyms: Vagalapilla imbricata imbricata (Gartner 1958) sensu Bukry (1969) - according to Burnett 1997 the specimens illustrated by Bukry 1969 as V. imbricata imbricata are better placed in S. mielnicensis.
Taxonomic discussion: The type figure is almost featureless so it is not entirely clear why this name ended up applied to this species. [my interpretation - JRY 2019]
