Corydoras filamentosus & CW143
Posted: 12 Dec 2020, 17:19
Hi,
Corydoras filamentosus belongs to acutus group, lineage 1.
Similar story as with C. spilurus, the tissue sample used within the framework of the phylogeny of Alexandrou et al. 2010 belonged to the sympatric CW143 which belongs to lineage 8. I have discussed this with Raphael Covain and he only realised after the publication that the tissue samples he sent (MHNG 2707.015-SU07-625) belong to the mimic species,
see pictures here: Corydoras filamentosus and Corydoras sp. "CW143".
So you have it swapped, whether your pictures are are correctly assigned is IMHO impossible to tell with the given picture quality. The body shape is nearly identical, the bets criterion to differentiate is the pectoral spine serration.
Cheers,
