Oklahoma Treehoppers (Homoptera, Membracidae)

Transcription

1 PROC. OF THE OKLA. ACAD. OF SCI. FOR a) 2. a) S. a) Oklahoma Treehoppers (Homoptera, Membracidae) CLIFFORD J. DENNIS, Wisconsin State University, Whitewater Treehoppers are mostly active, rather abundant and often bizarre insects. They inhabit a variety of trees, principally oaks, and herbaceous vegetation. As would be expected in Oklahoma, the tree-inhabiting forms largely are found in the more wooded eastern sections, while those that frequent herbs or both herbs and trees are found rather widely distributed. Until recently Oklahoma treehoppers have been neglected. References occur in certain of my previous papers (Dennis, 1960, 1962, 1963, 1964a This paper includes keys for the determination of Oklahoma species as well as county distribution records and host plants when known. Specimens collected at both "black" and "white" light traps previously have been reported (Dennis, 1964a). This work was supported in part by Frontiers of Science Foundation of Oklahoma. Special thanks are due James Harlow, Executive Vice President of this organization. The following people loaned material for study or participated in collecting: George Byers of the University of Kansas, W. A. Drew and James Shaddy of Oklahoma State University, Dan Shorter and LeRoy Rader of Northwestern State College, Thomas Gray and Foster Mayer of Southwestern State College, E. Phil Rouse of the University of Arkansas and two of my sons, Al and Roy Dennis. Richard Froeschner of the U.S. National Museum provided collection records. To all of these I wish to express my grateful appreciation. KEy TO SUBFAMILIES- Scutellum distinctly visible.1.

Dennis (1952) further modified generic assignments. Since keys based on male genitalia are of no use when one has a female to identify, this key to Oklahoma species does not use genital characters. It can be used for both sexes. 1. a) Base of corium with three longitudinal veins beginning near the base; pronotum not much elevated in front..2 Base of corium with two longitudinal veins contiguous at their bases; pronotum much elevated in front 3 2. a) Elytra with five apical cells, veins usually dark _..... _,AcutaliB tartarea (Say) Elytra with four apical cells, veins usually very indistinct.. _.. _.._.Micmtalia calva (Say) ~~~~~ ~~~p~h~=r:~~~... ::::::::::::::~::::::::::::::::~::::~::::~:~:::::::~::::~==:~::: Front of metopidium nearly vertical, its ridged sides meeting ahead of the middle of the pronotum _ TOTtwtilua.t&ermu (Fabrlch18) Pronotum not as above a) Metopidium seen from the front regularly narrowing to the peak; posterior median carina of pronotum not reddilh; femora often black....8twtocephala '"tea (Walker) Metopidlum seen from the front noticeably broadened above the head; posterior median carina of pronotum otten reddish; femora not black _..._.
