Nomenclatural changes in the grass-feeding Mexican leafhopper genus Cocrassana Blocker & Larsen (Hemiptera: Cicadellidae: Deltocephalinae: Athysanini)

ABSTRACT Two nomenclatural changes are proposed in the tribe Athysanini (Cicadellidae: Deltocephalinae). Chlorotettix sexvarus DeLong, 1959, is newly placed in the genus Cocrassana Blocker & Larsen and is a senior synonym of the type species of Cocrassana, C. riepmai Blocker & Larsen, 1991, syn. nov. A revised diagnosis and illustration of the species are provided.

First host record for Anteon pilicorne (Ogloblin) (Hymenoptera: Dryinidae), a parasitoid of Cicadellidae, including the corn leafhopper (Hemiptera: Cicadellidae)

For the first time the dryinid wasp Anteon pilicorne (Ogloblin) is recorded as a parasitoid of two Macrostelini leafhoppers: Balclutha rosea (Scott) and the corn leafhopper Dalbulus maidis (DeLong & Wolcott). New distributional records are presented.
