Distribution
Figs 1, 2
This genus is distributed from the Neotropics (Costa Rica, Mexico) to central and eastern United States (
Yu et al. 2012
).
Deans et al. 2003
mentioned
Alphomelon winniewertzae
from Canada (Ontario, Marmora, one female specimen deposited in the CNC), and
Fernandez-Triana 2010
recorded the species as also present in the province of Quebec, without giving more details. Here complete information of that second record is provided for the first time (Quebec, Old Chelsea, Gatineau Park, Summit of King Mountain, one female specimen deposited in the CNC). The species has been reported by
Deans et al. 2003
as a parasitoid of
Calpodes ethlius
and
Euphyes vestris
(
Lepidoptera
:
Hesperidae
). Based on the information available,
Alphomelon winniewertzae
could be distributed in Canada in an area between the rivers Ottawa and Saint Lawrence (44-45°N, 77-78°W). That represents less than 5% of the global range of the species.
Alphomelon
is mostly a Neotropical genus, with only three species reaching the Nearctic (mostly southern and eastern US), and
Alphomelon winniewertzae
is the only known in Canada and the northenmost species of the genus.
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 (most 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 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 two localities in Canada. Limiting biological factors: Unknown.
