Megachile funnelli is not widely recognized in authoritative taxonomic databases or major entomological references. No reliable encyclopedic sources currently provide detailed information on its classification, description, distribution, or ecological characteristics.
The name follows the binomial nomenclature format used for species in the genus Megachile, a large group of bees commonly known as leafcutter or mason bees. The specific epithet funnelli likely honors an individual with the surname Funnell, which is a common practice in species naming, but this etymology cannot be confirmed without access to the original description.
Accurate information is not confirmed.
