Identification
When treated as distinct, Nannodioctria were characterized by reduced and small body size relative to other Dioctriinae. The distinction from the main Dioctria group relies on subtle characters of the male terminalia and reduction. These features are now generally considered to represent intrageneric variation rather than generic-level divergence.
