Hyptia deansi
''Hyptia deansi'' is an extinct species of ensign wasp in the family Evaniidae known from a solitary Late Oligocene to Early Miocene fossil found in Mexico. ''H. deansi'' is the only species in the genus ''Hyptia'' to have been described from fossils and the only ensign wasp described from Mexican amber.
==History and classification==
''Hyptia deansi'' is known from a single fossil, the holotype adult, which is an inclusion in a transparent chunk of Mexican amber. The amber specimen, number ''SMNS MX–440'', is currently housed in the fossil collection of the State Museum of Natural History Stuttgart in Baden-Württemberg, Germany. The holotype is composed of a fully complete adult female. Mexican amber was recovered from fossil-bearing rocks in the Simojovel region of Chiapas, Mexico. This amber predates a range from between 22.5 million years old, for the youngest sediments of the Balumtun Sandstone, and 26 million years, for the La Quinta Formation, in which specimens are found. This age range, which straddles the boundary between the Late Oligocene and Early Miocene, is complicated by both formations being secondary deposits for the amber; consequently, the given age range is only the youngest that the fossil might be.
The holotype was first studied by paleoentomologists John T. Jennings and Stephen Mew, both of the university of Adelaide in conjunction with Lars Krogmann of the State Museum of Natural History Stuttgart. Jennings and his coauthor's 2012 type description of the species was published in the online journal ''Zootaxa''. The specific epithet ''deansi'' is in honor of Andy Deans of North Carolina State University in recognition for his efforts to generate new interest in the family Evaniidae.〔
