Published online by Cambridge University Press: 31 May 2012
Extract
This is the first of a series of papers which will consider the systematics of the Canadian and Alaskan Fulgoromorpha. The aim is to produce eventually a work on the Fulgoromorpha similar to that on the Cicadellidae of the same area by Beirne (1 956).
The two Delphacid genera Achrotile Fieber and Laccocera Van Duzee can be recognized by the presence of distinct pits on the frons, notum and abdominal dorsum. The frons in Achrotile has two median parallel carinae whilst only one is present in Laccocera.
