two different gen. et sp. indet?

[Siyan Zhao]

I'm finishing my undergraduate thesis, but I need to describe a species that has actually been published as Euselachii(a cohort of chondrichthys) gen. et sp. indet..  I agree this name, So in systematic paleontology whether it  is correct to still use "Euselachii gen. et sp. indet." as its name? In addition, if I Find one species but consider it as other kind of Euselachii but still is gen. et sp. indet, how to name the latter? 

Thanks so much.

Sorry, no idea. Maybe it is better to ask this question on Researchgate.net.  There you can reach hundreds of authors who work scientifically in the field of paleontology and who have to deal with tricky questions of nomenclature.

Look at the ICZN code:

I have seen workers number undescribed species: Composita sp. 1.

I believe it is appropriate to call them gen. et sp. indeterminate. 1 (or A), gen. et sp. Indeterminate 2 (or B), and so on.  You are not formally naming these taxa, you are just labeling them so you can write about them without confusion about which one you are referring to.

All helpful suggestions. Thank you so much!

Is it indet because it has not been described or is it indet because it can't be identified to taxon? If it is diagnosable but not described, then perhaps you have a responsibility to diagnose and describe it. If it is not diagnosable, then attribute it to the lowest taxonomic unit possible (e.g. family level or whatever).
