我们修改和关键Trachymyrmex蚂蚁发生在北美墨西哥北部。我们确认了9个物种，包括一个来自亚利桑那州南部的新种：T。arizonensis（惠勒）、T. carinatus Mackay & Mackay，T. desertorum（惠勒），T. jamaicensis（André），T. nogalensis Byars，T. pomonae Rabeling & Cover sp. nov.，T. septentrionalis（麦库克）、T. smithi Buren和T. turrifex（惠勒）。两个种下分类群是合群的：T. smithi neomexicanus科尔syn. nov.（= T. smithi）和T. turrifex caroli惠勒综合征nov.（= T. turrifex）。我们简要地描述了以前未描述的女王的T。desertorum和T. nogalensis和T. desertorum和T. turrifex。我们包括识别工人，皇后和男性的关键，沿着与所有物种的分布图。利用线粒体基因细胞色素氧化酶I（Cytochrome Oxidase I）和核蛋白编码基因延伸因子1-α（Elongation Factor 1-α）F1拷贝第一内含子（F1 copy）的部分DNA序列信息，进行系统发育分析，以表征每个物种几个居群种内和种间的遗传变异。分子系统发育分析支持我们的分类结论，关于北美Trachymyrmex种。
We revise and key Trachymyrmex ants occurring in North America north of Mexico. We recognize nine species, including one new species from southern Arizona: T. arizonensis (Wheeler), T. carinatus Mackay & Mackay, T. desertorum (Wheeler), T. jamaicensis (André), T. nogalensis Byars, T. pomonae Rabeling & Cover sp. nov., T. septentrionalis (McCook), T. smithi Buren, and T. turrifex (Wheeler). Two infraspecific taxa are synonymized: T. smithi neomexicanus Cole syn. nov. (= T. smithi) and T. turrifex caroli Wheeler syn. nov. (= T. turrifex). We briefly characterize the previously undescribed queens of T. desertorum and T. nogalensis, and the males of T. desertorum and T. turrifex. We include keys for the identification of workers, queens and males, along with distribution maps for all species. A phylogenetic analysis of DNA sequence information for parts of the mitochondrial gene Cytochrome Oxidase I and the first intron of the F1copy of the nuclear protein-coding gene Elongation Factor 1-α is used to characterize the intraversus inter-specific genetic variation of several populations per species. The molecular phylogenetic analysis supports our taxonomic conclusions concerning the North American Trachymyrmex species.
