Distribution

Figs 29, 30

According to the original description ( Fernandez-Triana 2010) this species is widely distributed in eastern Canada (Nova Scotia, Annapolis Royal, Bridgetown, Sable Island, Halifax; Prince Edward Island, Blooming Point; Quebec, Knowlton, Kazabazua; all specimens deposited in the CNC). It is the only Canadian endemic of the genus Venanus (Canada comprises 100% of the global range for the species), and it has been reported by Fernandez-Triana 2010 as a parasitoid of Caloptilia asplenifoliella ( Lepidoptera : Gracillariidae ).

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, although the species has been repeatedly collected over a span of 75 years, from mid August to early September. Threats: Residential and commercial development - medium to high (some of the areas where the species occur in Canada are already heavily populated); Agriculture and aquaculture - unknown; Human intrusions and disturbance - medium; Natural system modifications - high (alteration of the natural areas currently protected 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 a few localities in eastern Canada. Limiting biological factors: Unknown.
