Abstract
The species of the subgenus Castaneomyzocallis subg. nov. (genus Myzocallis) are found in North America on Castanea. Four species are classified in this subgenus: M. (C.) castaneae (Fitch) (type of subgenus); M. (C.) tissoti nom. nov.; M. (C.) nanae (Tissot); and M. (C.) castaneoides (Baker). The neotype of M. (C.) castaneae is established. The alate viviparae, the embryos, and the alatoid nymphs of M. (C.) castaneae, M. (C.) castaneoides, M. (C.) tissoti, and M. (C.) nanae are described. A key for the identification of the new subgenus is given. Attention is drawn to variations that may be caused by seasonal factors.
