New Species of Erythroneura Related to Lenta (Homoptera: Cicadellidae)

Abstract

Erythroneura lenta Beamer is one of a number of species having a very short or no posterior point on the foot of the style and single pygofer hooks. Most such species are found on oaks, although a few live on hickories, one on walnut, and a few questionable members of the complex on other hosts. The pygofer hooks vary from straight or falcate to strongly sinuate. Rearing data give the following host relationships: delongi on Quercus nigra, water oak; stephensoni and acantha on several of the red oaks; longa on Q. falcata var. falcata, southern red oak; patris on Q. falcata var. leucophyla (or pagodafolia), cherry bark oak; robusta and interna on Q. stellata, post oak; parvipes and era on Carya sp., hickories; and calamitosa on Juglans nigra, black walnut. Collection data give the following host relationships: metopia, alicia, and econa on Q. imbricaria, shingle oak; and lenta on Q. borealis, northern red oak. All the species named here have no or short posterior points on the feet of the styles. The drawings show the lateral view of the shaft of the aedeagus, the dorso-anterior view of the aedeagus, the lateral view of the pygofer and pygofer hook, and dorsal view of the pygofer hooks. The lateral view of the aedeagus is twice the magnification of the dorso-anterior view of the aedeagus (along its greatest length) and four times the magnification of the pygofer and pygofer hooks. All specimens were collected by the author unless otherwise stated. All holotype specimens will be deposited in the collections of the Illinois Natural History Survey.
