Prosena

Prosena species can be distinguished from other Dexiini genera by a combination of morphological features, though definitive identification to species level requires examination of male terminalia. The genus is characterized by features typical of the Dexiinae subfamily, including a generally robust body form. Specific diagnostic characters for the genus versus related taxa such as Dexia or Pseudodexia are not well-documented in readily accessible sources.

Distribution records from GBIF indicate presence in Denmark (DK), Norway (NO), and Sweden (SE). The genus has a broader global distribution based on species descriptions, with records from the Palearctic, Nearctic, and Oriental regions, though comprehensive distribution data is fragmented across individual species accounts.

As members of the Tachinidae family, Prosena species function as parasitoids, though specific host records and ecological impacts remain poorly documented. The genus contributes to the diversity of tachinid parasitoid assemblages in regions where it occurs.

• DexiaBoth Dexia and Prosena belong to the tribe Dexiini and share general morphological similarities in body form; they can be confused without careful examination of specific diagnostic characters.
• PseudodexiaAnother genus within Dexiini that resembles Prosena in overall habitus, requiring detailed morphological study for accurate separation.
