All previously known specimens (a total of 23) of Pseudapanteles gouleti had been collected in an area bounded by the Saint Lawrence and Ottawa rivers (44–46°N and 74–75°W, for details on localities and collecting dates, see the original description in Fernandez-Triana 2010). Here two new localities are reported for the first time (Ontario, Guelph, near Starkey Hill Conservation Area, and Saint Lawrence Islands National Park, Jones Creek by Mallorytown, County Road 5, specimens deposited in BIO). With the new data, the known distribution of the species is slightly expanded, but still remains an endemic species from southern Ontario (43–46°N and 74–80°W), Canada comprising 100% of the global range for the species. Pseudapanteles gouleti is the northernmost known species of the genus Pseudapanteles, and has been reported by Fernandez-Triana 2010 as a parasitoid of Paraclemensia acerifoliella (Lepidoptera: Incurvariidae).

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 the species has been collected over a span of 60 years between mid July to August (with one record on early September). Threats: Residential and commercial development – medium to high (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. Small extent of occurrence or area of occupancy: Recorded from a few localities in Canada. Limiting biological factors: Host distribution (limited to southeastern Canada) may affect the distribution of the wasp in the country.
