Elephantomyia longirostris
''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 described from Baltic amber.
==History and classification==
''Elephantomyia (Elephantomyia) longirostris'' is known from the holotype specimen, collection number MB.J.337, along with ten further adults which are preserved as inclusions in transparent Baltic amber. As of 2015, nine of the amber specimens were included in the collections of the Polish Academy of Sciences, while another was housed at the Natural History Museum Humboldt University, and the last resided in a private collection.〔 Baltic amber is recovered from fossil bearing rocks in the Baltic Sea region of Europe. Estimates of the age date between 37 million years old, for the youngest sediments and 48 million years old. This age range straddles the middle Eocene, ranging from near the beginning of the Lutetian to the beginning of the Pribonian.
''E. longirostris'' is one of six crane fly species in the genus ''Elephantomyia'' described from the Baltic amber, the others being ''E. baltica'', ''E. bozenae'', ''E. brevipalpa'', ''E. irinae'', and ''E. pulchella''.〔 All six species are placed into the ''Elephantomyia'' subgenus ''Elephantomyia'' based on the lack of tibial spurs and by several aspects of the wing morphology.
The fossil was first studied by entomologist Hermann Loew of the Germany, with his type description of the new species being published in 1851 as ''Toxorhina longirostris'', though he published the nomen nudum name a year earlier. The species was moved to the genus ''Limnobiorhynchus'' in 1860 by Carl Robert Osten-Sacken, and later moved by Osten-Sacken again, this time to the genus ''Elephantomyia''. The fossils were reexamined and the species redescribed in 2015 by paleoentomologist Iwona Kania of the University of Rzeszów, who examined the holotype and the ten additional specimens. Kania noted that two of the specimens Loew had placed into the species did not match the type description or redescription well, each having a notably short rostrom. Further study of the two was suggested to clarify the species and genus they belong to.〔
