Tribe Idiosystanini Emeljanov, 1995

[Back to “Higher classification of Delphacidae”]
[Back to “A checklist of New World delphacid species“]

Family Delphacidae Leach 1815

Subfamily Asiracinae Motschulsky, 1863: 108.

Tribe Idiosystanini Emeljanov 1995: 780.

The tribe was named by Emeljanov (1996) (first published in 1995 in Russian), although he attributed the name to Asche (1985; possibly referring to ‘idio-systati’ label used in the figure on page 264, as opposed to the ‘Asiracii’ within the Euasiracina).  Asche (1985) defined the characters of this group, but didn’t actually name it.  The name should be attributed to Emeljanov (1995: 780), despite Emeljanov’s attribution to Asche.

I will present the features of the tribe here sometime in the future.

The tribe includes 3 genera, all New World, as follows:

A detailed look at the features of the subfamily Asiracinae is here.
