Distribution

Figs 27, 28

This species is widely distributed in the New World, from Brazil to Canada ( Yu et al. 2012 Mason 1981, Mason 1981). Here new localities and collecting dates are provided for 20 Canadian specimens deposited in the CNC (Ontario, Simcoe, Vineland, Chambers Corner, Courtland, Rondeau Provincial Park, St. Williams, Saint Lawrence National Park, Thwartway Island; Manitoba, Delta). Canada comprises less than 20% of the global range for the species and the northernmost limit. It has been reported as a parasitoid of several species in the genera Chionodes and Dichomeris ( Lepidoptera : Gelechiidae ) (information summarized in Yu et al. 2012).

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, but specimens have been collected between June and August (although no specimen has been collected since 1976). Threats: Residential and commercial development - medium to high (some of the areas where the species occur are already heavily populated); Agriculture and aquaculture - unknown; Human intrusions and disturbance - medium; Natural system modifications - high (alteration of the areas 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 but likely low (climate change increasing the temperatures would not affect much the presence of this species in Canada, because it is already distributed in warmer areas). Small extent of occurrence or area of occupancy: None. Limiting biological factors: Unknown.
