我们根据J. Trager收集的标本和其他博物馆标本对新北极特有的白斑福木类群进行了修正。后一种材料来自于30年来积累的样本，这些样本既来自于F. pallidefulva群物种的自由生活群体，也来自于Polyergus lucidus s.l .群体中的“奴隶”群体，这些群体有单一物种的宿主群体。在该类群目前可用的名称中，四个有效的分类群是F. archboldi， F. dolosa， F. incerta和F. pallidefulva。还有第五种常见的，但以前未被认识的新物种，在这里被描述为Formica biophilica Trager， n. sp。这一群体的早期分类受到类型学思维和对度量特征处理不足的限制。在本研究中，除1个分类单元外，对所有保存完好的个体、巢系和类型进行了研究。重点分析了大毛纲的形态、长度、丰度和分布；小毛毛的长度和密度（短柔毛）；标准测量和指标；不同物种的生境偏好不同；本研究结果表明，无虫F. incerta n. stat., revstat .和F. biophilica n. sp.值得作为物种承认，F. nitidiventris是F. pallidefulva的同义词，F. schaufussi是F. pallidefulva的同义词。因此，目前的schaufussi概念（在选型上是不正确的）必须让位于同一种群的下一个可用名称dolosa n. stat。在本文中，我们提供了所有物种的诊断，定性形态学特征，表列的数量特征，自然史笔记以及工蜂的钥匙。与其他密切相关的蚁群（如Umphrey, 1996; Steiner et al., 2006）一样，形态是可变的，部分重叠，当基于由三个或更多处于最佳状态的工蚁组成的巢系列时，物种的确定将更加确定。
We revise the Nearctic endemic Formica pallidefulva group based on study of types and other museum specimens and material in J. Trager’s collection. The latter material originates from 30 years of accumulated samples, both from free-living colonies of F. pallidefulva group species, and from “slave” populations in colonies of Polyergus lucidus s. l., which have single-species host populations. Among the currently available names for the group, the four valid taxa are F. archboldi, F. dolosa, F. incerta and F. pallidefulva. There is a fifth common, but previously unrecognized new species, described here as Formica biophilica Trager, n. sp. Earlier taxonomies of this group were constrained by typological thinking and inadequate treatment of metric characters. For this study, well preserved individuals, nest series and types of all but one taxon were studied (no types seen for F. pallidefulva). Analysis focused on form, length, abundance and distribution of macrochaetae (pilosity); length and density of microchaetae (pubescence); standard measurements and indices; distinct habitat preferences of the various species; and host selection by Polyergus lucidus, s. l. Our results leave little doubt that F. incerta n. stat., rev. stat. and F. biophilica n. sp. deserve recognition as species, that F. nitidiventris is a synonym of F. pallidefulva and that F. schaufussi is a synonym of F. pallidefulva. Thus, the current concept of schaufussi (incorrect in reference to the lectotype) must give way to the next available name for the same population, dolosa n. stat. In this paper, we provide diagnoses, qualitative morphological characteristics, tabulated quantitative characters, natural history notes for all species and a key to the workers. As occurs in other groups of closely related ant species (e.g. Umphrey, 1996; Steiner et al., 2006), morphology is variable and partially overlapping, and species determinations will be more certain when based on nest series consisting of three or more workers in prime condition.
