How to query the NCBI Taxonomy database in ETE?
ETE’s ncbi_taxonomy module provides utilities to efficiently query a local copy of the NCBI Taxonomy database. The class NCBITaxonomy offers methods to convert from taxid to names (and vice versa), to fetch pruned topologies connecting a given set of species, or to download rank, names and lineage track information.

How to extract the smallest ETE tree in NCBI?
The method NCBITaxa.get_topology () allows to query your local NCBI database and extract the smallest tree that connects all your query taxids. It returns a normal ETE tree in which all nodes, internal or leaves, are annotated for lineage, scientific names, ranks, and so on.
How to use automatic tree annotation in NCBI taxonomy?
Automatic tree annotation using NCBI taxonomy. NCBI taxonomy annotation consists of adding additional information to any internal a leaf node in a give user tree. Only an attribute containing the taxid associated to each node is required for the nodes in the query tree. The annotation process will add the following features to the nodes:
