Hi,

this should be a male and female of Lathyrophthalmus aeneus syn. Eristalinus aeneus, right ? I've read that this species is related to the coast, thats why I'am not 100% sure. Can anyone please teach me on how to find the right established scientific name when there is a synonym ? Taking this species as example: Is it Lathyrophthalmus aeneus Syn. Eristalinus aeneus or Eristalinus aeneus Syn. Lathyrophthalmus aeneus ?



Location: Munich, Germany very close to the river Isar. (alpine upland)
Size: aprox 9mm


The male ...

Hi,

Where did you find this name Lathyrophthalmus. No trace in Fauna europaea. This is to be found in zipcodezoo.com http://zipcodezoo...s_astrops/, but I don't know in which region of the world.

I have a book of 2002 (Kurt Kormann "Schwebfliegen und Blasenkopffliegen Mitteleuropas" ) where this species is described as Lathyrophthalmus aeneus (SCOPOLI, 1763) :|

---

Now correctly there is Eristalinus Rondani, 1857 as genus, Lathyrophthalmus Mik, 1897 as subgenus of Eristalinus, for E. aeneus for example. See also: Perez-Banon C., Rojo S., Stahls G. & Marcos-Garcia M. A. Taxonomy of European Eristalinus (Diptera: Syrphidae) based on larval morphology and molecular data // European Journal of Entomology. — 2003. — Vol. 100, No. 3. — P. 417–428.

So, the correct name would be Eristalinus (Lathyropthalmus) aeneus! :D

Thank you. A few days ago I had a similar discussion about the synonym of the species Leucozona glaucia. How about the synonym of Leucozona glaucia Syn.: Ischyrosyrphus glaucius ?
