Mallada basalis is a species of green lacewing in the family Chrysopidae, first described by Francis Walker in 1853. No subspecies are listed in the Catalog of Life. The species was detected on mainland New Zealand in the 2010s.

Mallada basalis has been identified on the Eastern states of Australia, the Philippines, Taiwan, the Ryukyu Islands, Micronesia and Polynesia (including an outlier population on Easter Island). Mallada basalis has been seen living in both suburban and native flora environments.
The first confirmed sighting of Mallada basalis in New Zealand was in 1940 on the Kermadec Islands, though evidence of the species may go back as far as 1908. In 2010, a specimen was identified on Tiritiri Matangi Island in the Hauraki Gulf, and the first specimen in Auckland was identified in 2016. By 2020, Mallada basalis was present across the...

GBIF citizen-science records
It is estimated from how often the Mallada basalis is recorded against all the insects logged in Auckland (435 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.
