Taxonomic history
Idiolispa was established by Townes in 1962 as part of his comprehensive revision of the Ichneumonidae. The name derives from Greek 'idios' (distinct, peculiar) and 'lispa' (a smooth or polished appearance), referring to the relatively smooth and shiny characteristic of the group.
Collection rarity
With only 11 observations recorded on iNaturalist and limited museum specimen records, I. aestivalis appears to be genuinely rare or undercollected. This may reflect genuine rarity, cryptic habits, or collection against small, non-mimetic ichneumonids.
