However, homoplasy is a portmanteau term for classes of similarity otherwise subsumed under terms such as convergence, parallelisms, reversals, rudiments, vestiges, and atavisms.
Webconvergence. Traditionally, homoplastic traits are seen as convergent (i) if they appear in distantly related groups or (ii) if they are realized by distinct developmental mechanisms. Jablonski instead links convergent and parallel evolution to two distinct patterns of character state changes in a phylogenetic tree (Figure 1).

I have here taken homoplasy to refer to a phylogenetic concept: two traits are homoplastic just in case the common ancestor did not have the trait.
Homoplasy, in biology and phylogenetics, is the term used to describe a feature that has been gained or lost independently in separate lineages over the course of evolution. This is different from homology, which is the term used to characterize the similarity of features that can be parsimoniously explained by common ancestry.
