Classification: Mesozoic -> Eiffellithales -> Chiastozygaceae -> Staurolithites -> Staurolithites mielnicensis
Sister taxa: << < S. eiffellithoides, S. flavus, S. halfanii, S. minutus, S. ngurumahambaensis, S. quadriarcullus, S. siesseri, S. coroniformis, S. gausorhethium, S. leptostaurus, S. dorfii, S. handleyi, S. imbricatus, S. laffittei, S. lumina, S. mielnicensis, S. mitcheneri, S. angustus, S. mutterlosei, S. zoensis, S. aachenus, S. aenigma, S. dicandidula, S. ellipticus, S. elongatus, S. integer, 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.
Notes & 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]
