dc.description.abstract The current classification of weevils has witnessed vast improvements at higher phylogenetic levels, though much remains unstable at the lower levels. In order to develop a more robust morphological character system for cladistic analysis of the higher lineages and to gain a comprehensive understanding of the structure of a hallmark feature of weevils, a comparative study was conducted of rostra throughout Curculionoidea. Semithin sections were made of the rostra of 36 exemplar genera representing all seven currently recognized weevil families, as well as 19 of 21 subfamilies within the largest family, Curculionidae, and internal structures were examined for phylogenetically informative characters. While the morphological diversity of rostral forms is impressive, general trends are apparent with respect to life-history traits and modes of feeding. Exploration of internal rostral morphology has yielded valuable but previously unexplored characters that greatly complement the external characters of this structure. Together, these features provide new insight for settling current incongruence at the higher levels of classification. en_US

This item appears in the following Collection(s)

  • Bulletin of the American Museum of Natural History
    The Bulletin, published continuously since 1881, consists of longer monographic volumes in the field of natural sciences relating to zoology, paleontology, and geology. Current numbers are published at irregular intervals. The Bulletin was originally a place to publish short papers, while longer works appeared in the Memoirs. However, in the 1920s, the Memoirs ceased and the Bulletin series began publishing longer papers. A new series, the Novitates , published short papers describing new forms.
