The ant is closely related to Hypoponera ergatandria and bears several similarities, such as colony size and appearance.
Hypoponera punctatissima is a tramp species that has invaded many countries past its native range, where it resides in heated buildings, and outdoor heated habitats such as animal waste and fermenting waste. The ant is considered native in the Gulf of Guinea, Kenya, Uganda, Rwanda, Tanzania and Kenya. The ant is also native to much of southern Africa, with a native presence in Angola, Zambia, Mozambique, Botswana and South Africa.

Of the 2 cities where we can rate Roger's Crypt Ant sightings, Miami ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Bengaluru (India, under 5%).
GBIF citizen-science records
It is estimated from how often the Roger's Crypt Ant is recorded against all the insects logged in Miami (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
