Tribe Idiosystatini Emeljanov 1996


Overview - Tribe Idiosystatini

Family Delphacidae Leech 1815

Subfamily Asiracinae Fieber 1892

Tribe Idiosystanini Emeljanov 1996

The tribe was named by Emeljanov (1996), based partly on characters developed by Asche (1985).  Emeljanov (1996) attributed the tribe to Asche (1985), who recognized these three genera has being closely related; but Asche (1985) used the grouping in an informal sense.  I will present the features of the genus here in the future.

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