In different parts of the world, Tunga Penetrans is called by various synonyms such as sand flea, chigger, no-see-um, punkie, bicho de pie, pique, suthi, and ngiga. These terms are often used interchangeably, although they may refer to different species and genera of fleas, mites, and biting midges that share similar morphology and behavior. To avoid confusion, it is important to use the scientific name Tunga Penetrans when identifying and treating these parasites.
