The goals of this dissertation research project to be performed by Steven O. Shattuck and Professor Philip S. Ward of the University of California at Davis are to define genera within the ant sub-family Dolichoderinae (about 1000 species worldwide, in 31 genera) and attempt to demonstrate their monophyly (having one ancestral origin) based on morphological traits of workers, queens, males, and larvae. Other goals are to analyze cladistic relationships among these groups using rigorous methods of phylogenetic inference, develop a key to all known genera based on the above-mentioned character analysis, and compile a species- level catalog of all taxa (including information on current generic status, type locality, and if available, location and number of type specimens). Preserved material at existing museum collections in the United States, Canada, and the United Kingdom will be examined for characters suitable for cladistic analysis. Hypotheses about relationships among genera will be evaluated by examining congruence between worker, queen, and male ant data sets and by statistical estimation of cladogram confidence limits. Results will identify natural units for alpha-taxonomic studies, provide a foundation for species-level phylogenetic investigations by elucidating sister-group relationships among genera, and assist in access to the taxonomic literature on the Dolichoderinae.

本论文研究项目由加州大学戴维斯分校的 Steven O. Shattuck 和 Philip S. Ward 教授执行，其目标是定义蚂蚁亚科 Dolichoderinae（全世界约 1000 个物种，31 个属）内的属，并尝试根据工蚁、蚁后、雄性和幼虫的形态特征证明它们的单系性（具有一个祖先起源）。 其他目标是使用严格的系统发育推断方法分析这些类群之间的分支关系，根据上述特征分析开发所有已知属的关键，并编制所有类群的物种级目录（包括有关当前属状态、模式产地的信息，以及模式标本的位置和数量（如果有））。 将检查美国、加拿大和英国现有博物馆藏品中保存的材料中是否有适合分支分析的特征。 关于属之间关系的假设将通过检查工蚁、蚁后和雄性蚂蚁数据集之间的一致性以及分支图置信限的统计估计来评估。 结果将确定用于α分类学研究的自然单位，通过阐明属之间的姐妹群关系为物种水平的系统发育研究提供基础，并有助于获取有关长头虫亚科的分类学文献。
