Aptenoperissus burmanicus

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 capable of 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.

Time the record covers

At most 6.6 million years on record.

The one occurrence read is dated to somewhere between 100.5 Mya and 93.9 Mya, which is a dating window rather than a span.

1 occurrence of Aptenoperissus burmanicus on record, most of them in the Late Cretaceous. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

1 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.
