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. [1]
Melitta is a form of the Greek word μέλισσα (melissa), "honey bee", [2] while Sphex is a transliteration of the Greek word σφήξ, wasp. [3]
M. burmensis is approximately one-fifth the size of the extant honeybee, at about 3 millimetres long. [4] 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. [5]
Poinar and bee researcher Bryan Danforth described M. burmensis in the journal Science .
Bees are winged insects closely related to wasps and ants, known for their roles in pollination and, in the case of the best-known bee species, the western honey bee, for producing honey. Bees are a monophyletic lineage within the superfamily Apoidea. They are presently considered a clade, called Anthophila. There are over 16,000 known species of bees in seven recognized biological families. Some species – including honey bees, bumblebees, and stingless bees – live socially in colonies while most species (>90%) – including mason bees, carpenter bees, leafcutter bees, and sweat bees – are solitary.
George O. Poinar Jr. is an American entomologist and writer. He is known for popularizing the idea of extracting DNA from insects fossilized in amber, an idea which received widespread attention when adapted by Michael Crichton for the book and movie Jurassic Park.
The Bostrichidae are a family of beetles with more than 700 described species. They are commonly called auger beetles, false powderpost beetles, or horned powderpost beetles. The head of most auger beetles cannot be seen from above, as it is downwardly directed and hidden by the thorax. Exceptions are the powderpost beetles, and members of the subfamily Psoinae.
Palaeoagaracites is an extinct monotypic genus of gilled fungus in the order Agaricales. It contains the single species Palaeoagaracites antiquus.
Mycetophagites is an extinct fungal genus of mycoparasitic in the order Hypocreales. A monotypic genus, it contains the single species Mycetophagites atrebora.
Myanmymar is an extinct genus of fairyfly preserved in Burmese amber from Myanmar. It has only one species, Myanmymar aresconoides. It is dated to the earliest part of the Cenomanian stage of the Late Cretaceous, around 99 million years old. As of 2011, it is the oldest known fossil mymarid.
Burmese amber, also known as Burmite or Kachin amber, is amber from the Hukawng Valley in northern Myanmar. The amber is dated to around 100 million years ago, during the latest Albian to earliest Cenomanian ages of the mid-Cretaceous period. The amber is of significant palaeontological interest due to the diversity of flora and fauna contained as inclusions, particularly arthropods including insects and arachnids but also birds, lizards, snakes, frogs and fragmentary dinosaur remains. The amber has been known and commercially exploited since the first century AD, and has been known to science since the mid-nineteenth century. Research on the deposit has attracted controversy due to its alleged role in funding internal conflict in Myanmar and hazardous working conditions in the mines where it is collected.
Melittidae is a small bee family, with over 200 described species in three subfamilies. The family has a limited distribution, with all described species restricted to Africa and the northern temperate zone.
Aptenoperissus is a genus of extinct wasp with eight described species, placed into the monotypic family Aptenoperissidae. The type species Aptenoperissus burmanicus resembles a mix between a grasshopper, an ant, and a wasp. It was described by a group of researchers from Oregon State University in a paper released online in October 2016. The piece of 100 million year old Burmese amber that it was preserved in was found in the Hukawng Valley of Myanmar in Southern Asia. A new family, Aptenoperissidae, was described to accommodate this insect. Species of Aptenoperissus were wingless, with a strong stinger. The creature had long legs making it perfect for jumping higher than most insects. Subsequently additional species were described from the Myanmar amber: A. amabilis, A. delicatus, A. formosus, A. etius, A. magnifemoris, A. pusillus and A. zonalis. Initially placed in Ceraphronoidea, later studies placed it in Stephanoidea.
Embolemidae is a family of small solitary parasitoid wasps with around 70 species in 2 genera distributed around the world. The few species whose biology is known are parasites on planthopper nymphs of the families Achilidae and Cixiidae. There is debate regarding the status of the genus named Ampulicomorpha by Ashmead in 1893, generally considered now to be a junior synonym of Embolemus (e.g.,), though some authorities dispute this (e.g.,)

Burmese amber is fossil resin dating to the early Late Cretaceous Cenomanian age recovered from deposits in the Hukawng Valley of northern Myanmar. It is known for being one of the most diverse Cretaceous age amber paleobiotas, containing rich arthropod fossils, along with uncommon vertebrate fossils and even rare marine inclusions. A mostly complete list of all taxa described up until 2018 can be found in Ross 2018; its supplement Ross 2019b covers most of 2019.
Discoscapa apicula is an extinct species of crabronid wasp, formerly considered one of the two oldest-known species of bees. The species was described from an amber inclusion in Burmese Amber in 2020 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, the same age as Melittosphex burmensis, likewise previously considered the oldest known bee species; as it comes from the same amber deposit, these two specimens are considered to be the same approximate age. More recent research has concluded that D. apicula is a wasp belonging to the subfamily Crabroninae, placed in its own tribe, Discoscapini.
