Axopodorhabdus dietzmannii


Classification: Mesozoic -> Podorhabdales -> Axopodorhabdaceae -> Axopodorhabdus -> Axopodorhabdus dietzmannii
Sister taxa: A. albianus, A. atavus, A. cylindratus, A. dietzmannii, A. rahla, A. sp.,

Distinguishing features: Axopodorhabdus with elongated, slightly flattened, elliptical outline (oblong shaped) with axial cross structure bearing a tall, hollow spine. Cross bars without medial extinction line in xpl.


Taxonomy:

Citation: Axopodorhabdus dietzmannii (Reinhardt, 1965) Wind & Wise, 1983
Rank: Species
Basionym: Ahmuellerella dietzmannii Reinhardt, 1965
Synonyms:
Notes & discussion: The combination was initially proposed in Wind & Wise, in Wise & Wind (1977) but the original publication was not cited directly hence the proposal was technically invalid and so was proposed again, validly, in  Wind & Wise 1983

Farinacci & Howe catalog pages: Ahmuellerella dietzmanni * , Podorhabdus septentrionalis *

Distinguishing features: Axopodorhabdus with elongated, slightly flattened, elliptical outline (oblong shaped) with axial cross structure bearing a tall, hollow spine. Cross bars without medial extinction line in xpl.


Morphology remarks: Readily confused with A. albianus but:
This range of differences indicates that these are two genuinely different species.
