Rivellia inaequata
Rivellia inaequata is a species of signal fly in the family Platystomatidae, described by Namba in 1956. The genus Rivellia comprises small flies associated with leguminous plants, with larvae typically feeding on nitrogen-fixing root nodules. Like other platystomatids, adults are characterized by distinctive wing patterns and constant wing movement during walking. The species is known from limited observations and appears to be far less documented than congeners such as R. quadrifasciata.
