Distribution

Figs 25, 26

This species is distributed in southern and eastern United States ( Yu et al. 2012). Fernandez-Triana 2010 mentioned the species from Canada (Ontario, Niagara Falls), without giving more details. Here complete information of those records is provided for the first time (two specimens deposited in the CNC). The Canadian specimens comprise less than 20% of the global range for the species and the northernmost limit. It has been reported as a parasitoid of Synanthedon scitula ( Lepidoptera : Sesiidae ) (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. Threats: Residential and commercial development - high (the areas where the species occur are already heavily populated); Agriculture and aquaculture - medium; Human intrusions and disturbance - high; 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: Recorded from one locality in Canada. Limiting biological factors: Host distribution (limited to southeastern Canada) may affect the distribution of the wasp in the country.
