The taxonomy ID of several species in genus Segatella are the same one 165179 .  
But in [NCBI taxonomy database](https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?mode=Undef&id=2974251&lvl=3&keep=1&srchmode=1&unlock), they are different species with various taxon ID. The 165179 is the exact taxon ID of _Segatella copri_.

```python
import pickle
import bz2
a = pickle.load(bz2.BZ2File("mpa_vJun23_CHOCOPhlAnSGB_202403.pkl", "r"))
a["taxonomy"]["k __Bacteria|p__ Bacteroidota|c __Bacteroidia|o__ Bacteroidales|f __Prevotellaceae|g__ Segatella|s __Sgatella_sinensis|t__ SGB1638"]
a["taxonomy"]["k __Bacteria|p__ Bacteroidota|c __Bacteroidia|o__ Bacteroidales|f __Prevotellaceae|g__ Segatella|s __Segatella_copri|t__ SGB1626"]

```

Is this an issue of database, or an intended record ?
