Rivellia metallica
(Wulp, 1867)
Rivellia metallica is a of signal fly in the Platystomatidae, first described by Wulp in 1867. Signal flies are recognized for their distinctive wing-waving , which serves intraspecific communication functions. The species epithet 'metallica' suggests a metallic appearance, though specific morphological details for this species remain poorly documented in available literature. Like other members of the Rivellia, it likely exhibits the family's characteristic 'signal' behavior involving patterned wing movements.

Identification
Definitive identification requires examination of male genitalia, as is standard for -level determination in Rivellia. Distinguished from by subtle morphological features not detailed in available sources.

Appearance
Specific morphological description unavailable. As a member of Platystomatidae, likely possesses the 's characteristic tubular mouthparts that give a 'gas mask' appearance. The epithet 'metallica' suggests metallic coloration. Wing patterns typical of Rivellia are expected but not confirmed for this species.
Distribution
Distribution details not available in provided sources. As a member of Rivellia, likely occurs in regions where related are found, though this remains speculative.
Behavior
Expected to exhibit the characteristic 'signal' wing-waving of Platystomatidae, wherein wings are kept in constant motion during to produce -specific visual signals for mate recruitment. This behavior is -wide and has been explicitly documented in such as R. quadrifasciata.
