Diolcogaster garmani (Ashmead, 1900)
Materials
Type status: Other material. Occurrence: recordedBy: Jose Fernandez-Triana; individualCount: 1; sex: female; Location: country: Canada; stateProvince: Ontario; verbatimLocality: Thamesville; Event: eventDate: 20.vi.1962; Record Level: institutionCode: CNC
Distribution
Figs 9, 10
This species is distributed in central and eastern United States ( Yu et al. 2012). Fernandez-Triana 2010 recorded the species as also present in the province of Ontario, without giving more details. Here complete information of that specimen is provided for the first time (Ontario, Thamesville, one female deposited in the CNC). This represent the northernmost record and less than 5% of the global range of the species. Diolcogaster garmani has been recorded as a parasitoid of Ogdoconta cinereola ( Lepidoptera : Noctuidae ) in the United States (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 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 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 southern Ontario and Quebec) may affect the distribution of the wasp in Canada.
