Ilisoa hawequas is known only from the type locality at Hawequas, where it occurs at approximately 483 metres above sea level.
The species builds small horizontal sheet webs in vegetation. The type specimen was collected by sifting humus, suggesting this species lives in leaf litter.
The species is named after Hawequas, its type locality in the Western Cape.
The species is known only from a single female and is potentially threatened by habitat loss due to agricultural activities, particularly vineyard expansion. It is listed as Data Deficient due to limited sampling.
