This species was described from a single female from Canada (British Columbia, Verde Creek, northeast from Copper Mountain, holotype deposited in the CNC). Exix is mostly a Neotropical genus, with only Exix columbica reaching the Nearctic, and no more species expected from North America ( Fernandez-Triana 2010, Mason 1981, Whitfield 1995). Nothing is known about the hosts caterpillars parasitized by this braconid wasp.

Conservation

Assessment using the prioritization criteria developed by COSEWIC. Existing global conservation status: None (species is not listed on Natureserve nor has it been assigned a Canadian national conservation status rank). Canadian population size and trends: No information on population size is available. Threats: Residential and commercial development - medium to high (the single area where the species occurs is populated); Agriculture and aquaculture - unknown; Human intrusions and disturbance - medium; Natural system modifications - high (alteration of the area would likely extirpate the species from Canada); Invasive and other problematic species and genes - unknown but likely low, unless another wasp species parasitizing the same host would be introduced (and then competing for the same host, an scenario not likely to occur); Climate change and severe weather - unknown. Small extent of occurrence or area of occupancy: Recorded from one locality in Canada (the only locality known for the species). Limiting biological factors: Unknown.
