A New Hylobius Weevil Associated With Jack Pine Stand Deterioration (Coleoptera: Curculionidae)

Abstract
During ecological investigations of the pine root collar weevil, Hylobius radicis Buchanan, in central Wisconsin sand plains, a weevil of similar appearance, but of different habits, was encountered. This weevil was identified tentatively as H. radicis with the available keys (Buchanan, 1934 and Finnegan, 1961), and in general fits the original morphological description of that species. However, differences in biological habits and morphology suggested that an undescribed species was involved (Millers, 1960 and Millers and Benjamin, 1961), and the taxonomic separation and description of the new species follows:
