Prorates
Melander, 1906
Prorates is a of small predatory in the (), established by Melander in 1906. The genus belongs to the Proratinae, which is characterized by distinctive morphological features and predatory habits. Members of this genus are poorly known biologically, with limited published information on their and . The genus is distinguished from other scenopinid genera primarily by structural characteristics of the , , and male terminalia.

Identification
Prorates can be distinguished from other by features of the male terminalia, including the structure of the hypandrium and . The is placed in the Proratinae based on antennal characteristics and . -level identification requires examination of male genitalic structures. The genus is most readily separated from the related genus Scenopinus by differences in head shape, structure, and details of the male reproductive apparatus.
Habitat
of Prorates have been collected in association with decaying wood and woody debris, suggesting a preference for forested or woodland environments where their presumed (small in decaying substrates) would be abundant.
Distribution
The occurs in North America and the Palearctic region. Records include the western United States and parts of Eurasia. Specific distribution data is sparse due to the rarity of specimens in collections and limited targeted efforts.
Ecological Role
As members of , of Prorates are presumed to be predatory on small , likely including other and found in decaying wood and similar microhabitats. Their ecological role is probably as regulators of of small arthropods, though direct evidence is lacking.
Human Relevance
No direct economic importance has been documented. The is of interest primarily to dipteran systematists and students of Asilomorpha .
