Melittosphex burmensis is an aculeate wasp that was formerly considered one of the two oldest-known species of bees. The species was described from an inclusion in Burmese amber in the year 2006 by George Poinar Jr., a zoologist at Oregon State University. The fossil was found in a mine in the Hukawng Valley of northern Myanmar and is believed to date from the Cretaceous Period, 100 million years ago.{{cite journal |author=G. O. Poinar, Jr. & B. N.

Etymology

Melitta is a form of the Greek word μέλισσα (melissa), "honey bee",[https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0058%3Aentry%3Dme%2Flissa μέλισσα], Henry George Liddell, Robert Scott, An Intermediate Greek-English Lexicon, on Perseus. while Sphex is a transliteration of the Greek word σφήξ, wasp.{{cite web|title=Sphex|url=http://www.merriam-webster.com/dictionary/sphex|publisher=Merriam-Webster|accessdate=22 June 2015}}

Description

M. burmensis is approximately one-fifth the size of the extant honeybee, at about 3 millimetres long.{{Cite journal|last1=Danforth|first1=Bryan N.|last2=Poinar|first2=George O.|date=September 2011|title=Morphology, Classification, and Antiquity of Melittosphex burmensis (Apoidea: Melittosphecidae) and Implications for Early Bee Evolution|url=http://www.bioone.org/doi/abs/10.1666/10-130.1|journal=Journal of Paleontology|language=en|volume=85|issue=5|pages=882–891|doi=10.1666/10-130.1|issn=0022-3360}} M. burmensis has some anatomical features similar to those of flesh-eating wasps, including the shape of its hind legs, but also some features of pollen-collecting bees, such as branched hairs on the body.

The sample discovered is thought to be 100 million years old, 40 million years older than the oldest known bee species. Subsequent research has rejected the claim that Melittosphex is a bee, or even a member of the superfamily Apoidea to which bees belong, instead treating the lineage as incertae sedis within the Aculeata.{{Cite journal|last1=Rosa |first1=B.
