Apomorphy can simply be defined as derived trait or character state that is distinct to a particular species or group in a phylogenetic tree down to its descendants. The example you cited is fine.
Plesiomorphy is an ancestral or primitive traits that are homologous to a certain group of organisms but not unique to the other members of the group, hence cannot be used as a diagnostic character for the group.
