Deinodryinus velteni is an extinct species of Deinodryinus in the wasp family Dryinidae. The species is known solely from an Eocene fossil found in the Baltic region. [1]
Deinodryinus velteni is known only from a single fossil, the holotype, an unnumbered specimen which is housed in the Paläontologie–Sektion Bernstein of the State Museum of Natural History Stuttgart in Germany. The specimen is a fully complete adult female wasp. The specimen is preserved as an inclusion in a transparent chunk of amber. [1] The amber dates to between forty and forty-five million years old, and, being Baltic amber that has been redistributed by the sea, a more specific type location than the Baltic region is not possible to identify. Deinodryinus velteni was first studied by paleoentomologists Adalgisa Guglielmino and Massimo Olmi, both of the University of Tuscia. Guglielmino and Olmi's 2011 type description of the new species was published in the online journal ZooKeys . [1] The specific epithet velteni is in honor of Jürgen Velten who loaned the authors specimens that they studied. D. velteni is the most recent of three Deinodryinus species to be described from the fossil record: Deinodryinus areolatus is also known from a fossil preserved in Baltic amber, while Deinodryinus? aptianus is known only from a Mongolian compression fossil in marl. [1]
The holotype specimen is a complete adult female with an overall coloration that is brown to black, except the palpi, which are a dull brick red. The female is 4.0 millimetres (0.16 in) in length, with antennae that are approximately three times the length of the head and macropterous forewings. The antennae are composed of ten segments, densely hairy, and distinctly club-shaped (clavate) in structure. The forewings have three cells at the base that are formed by pigmented veins. The forewings have a pterostigma which is approximately five times as long as it is wide, and a stigmal vein that is not S-shaped. Both the fore and hind wings are uniformly slightly darkened, rather than the glassy hyaline seen in the other two described fossil species of Deinodryinus. The length of the stigmal vein is used to separate D. areolatus and D. velteni, with the distal portion of the vein being much longer than the proximal portion in D. velteni as opposed to D. areolatus where the two portions are approximately the same length.

Dryinidae is a cosmopolitan family of solitary wasps. Its name comes from the Greek drys for oak: Latreille named the type genus Dryinus because the first species was collected on an oak tree in Spain. The larvae are parasitoids of the nymphs and adults of Auchenorrhyncha. Dryinidae comprises over 1900 described species, distributed in 11 extant subfamilies and 57 genera.
Baltic amber or succinite is amber from the Baltic region, home of its largest known deposits. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that this forested region provided the resin for more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014 and 400 tonnes in 2015.
Fibla carpenteri is an extinct species of snakefly in the Inocelliidae genus Fibla. F. carpenteri is named in honor of the paleoentomologist Dr Frank Carpenter, for his vast knowledge and interest in Raphidioptera.
Aspidopleura is an extinct monotypic genus of parasitic wasp in the Eupelmidae subfamily Neanastatinae and at present, it contains the single species Aspidopleura baltica. The genus is solely known from the Early Eocene Baltic amber deposits in the Baltic Sea region of Europe.
Neanaperiallus is an extinct monotypic genus of parasitic wasp in the Eupelmidae subfamily Neanastatinae containing only a single species, Neanaperiallus masneri. The genus is solely known from the Early Eocene Baltic amber deposits in the Baltic Sea region of Europe.
Palaeovespa is an extinct genus of wasp in the Vespidae subfamily Vespinae. The genus currently contains eight species: five from the Priabonian stage Florissant Formation in Colorado, United States, two from the middle Eocene Baltic amber deposits of Europe, and one species from the late Paleocene of France.
Dryinus grimaldii is an extinct species of wasp in the dryinid genus Dryinus. The species is solely known from the early Miocene, Burdigalian stage, Dominican amber deposits on the island of Hispaniola.
Dryinus rasnitsyni is an extinct species of wasp in the dryinid genus Dryinus. The species is solely known from the early Miocene, Burdigalian stage, Dominican amber deposits on the island of Hispaniola.
Lebanoraphidia is an extinct genus of snakefly in the family Mesoraphidiidae. The genus is solely known from Cretaceous, Upper Neocomian, fossil amber found in Lebanon. Currently the genus is composed of a single species Lebanoraphidia nana.
Deinodryinus? aptianus is an extinct species of Deinodryinus in the wasp family Dryinidae. The species is solely known from a Cretaceous fossil found in Mongolia.
Deinodryinus areolatus is an extinct species of Deinodryinus in the wasp family Dryinidae. The species is solely known from an Eocene fossil found in the Baltic region.
Astreptolabis is an extinct genus of earwig in the Dermaptera family Pygidicranidae known from a group of Cretaceous fossils found in Myanmar. The genus contains two described species, Astreptolabis ethirosomatia and Astreptolabis laevis and is the sole member of the subfamily Astreptolabidinae.
Arostropsis is an extinct genus of broad-nosed weevil in the beetle family Curculionidae known from an Upper Eocene fossil found in Europe. The genus contains a single described species, Arostropsis groehni.
Protostephanus is an extinct genus of crown wasp in the Hymenoptera family Stephanidae known from an Eocene fossil found in the United States of America. The genus contains a single described species, Protostephanus ashmeadi placed in the stephanid subfamily Stephaninae.
Thaumatodryinus tuukkaraski is a wasp species in the family Dryinidae. This tiny insect is endemic to Kenya where it is only known from the Taita Hills. In 2015, this newly discovered species was named in direct reference to former Boston Bruins (NHL) goaltender, Tuukka Rask.
Elephantomyia (Elephantomyia) longirostris is an extinct species of crane fly in the family Limoniidae. The species is solely known from the Middle Eocene Baltic amber deposits in the Baltic Sea region of Europe. The species is one of six in its genus described from Baltic amber.
Camelomecia is an extinct genus of stem-group ants not placed into any Formicidae subfamily and probably not into Formicidae itself. Fossils of the single known species, Camelomecia janovitzi, are known from the Middle Cretaceous of Asia. The genus is one of several ants described from Middle Cretaceous ambers of Myanmar.
