THE IDENTITIES OF PSYLLIDS (HOMOPTERA: PSYLLOIDEA) IN THE PROVANCHER COLLECTION, WITH THE DESIGNATION OF LECTOTYPES

Abstract

Provancher (1872, 1886) described eight species of psyllids from eastern Canada. Their identities have subsequently been confused, ignored, or regarded as doubtful by several authors, primarily because the original descriptions were imprecise and the location of type material unknown [see Hodkinson (1988) for summary]. Van Duzee (1912) excluded these species from his review of the synonymy of the Provancher Hemiptera. I have now examined the Provancher psyllid material deposited in the Department of Biology, University of Laval, Ste-Foy, Quebec, Canada. This paper clarifies the identity of species and designates lectotypes where appropriate. None of the specimens bear locality or host-plant data, although these data are usually given in rudimentary form in the descriptions. Provancher did not state numbers of specimens examined in his descriptions.
