Stephomyia eugeniae
Felt, 1913
Stephomyia eugeniae is a Neotropical gall midge in the Cecidomyiidae. The is known from male, female, and pupa stages and induces galls on Eugenia species (Myrtaceae). Phylogenetic analysis places it in a clade with S. epeugeniae, sister to a group containing S. tetralobae, S. rotundifoliorum, and S. espiralis.
