Distribution

Figs 5, 6

This species was described from a single female from Canada (Ontario, Ottawa, holotype deposited in the CNC). Fernandez-Triana 2010 mentioned two additional specimens from the same locality, without giving more details. Here complete information of those records is provided for the first time. The new data confirms the current presence of Clarkinella canadensis in Canada, so far only known from a single locality (100% of the global range of the species). Clarkinella is mostly a Neotropical genus, with only Clarkinella canadensis reaching the Nearctic, and no more species expected from North America ( Fernandez-Triana 2010, 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, but the only known specimens are all from a single locality, and have been repeatedly collected over a span of 50 years, usually during late July (but with one record from early September). Threats: Residential and commercial development - high (the single area where the species occurs in Canada is already heavily 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.
