Phytoseiidae (Acari) is the best known family of predatory mites. Within this family, Euseius Wainstein is one of the largest genera. The species of this genus have generalist feeding behavior, including in their diet mites and pollen. Some studies have demonstrated the potential of certain Euseius species to control pest mites. Euseius concordis (Chant) has been mentioned in the literature as potentially useful for the control of the tomato russet mite, Aculops lycopersici (Tryon) (Eriophyidae). Several other American species are morphologically similar to E. concordis; the morphological variation of these species is poorly understood. The objective of this study was a taxonomic re-evaluation of E. concordis and of the world species most similar to it. Measurements of species collected in this study and a taxonomic key to separate the species of this group are provided. Morphological evaluations confirmed that Euseius flechtmanni Denmark & Muma is a junior synonym of E. concordis, and determined that Euseius caseariae De Leon is also a junior synonym of E. concordis, that Euseius ho (De Leon) and Euseius brazilli (El-Banhawy) are junior synonyms of Euseius mesembrinus (Dean) and that Euseius vivax (Chant & Baker) is not a junior synonym of Euseius fructicolus (Gonzalez & Schuster), as previously thought.
植绥螨科（蜱螨亚纲）是最为人熟知的捕食性螨类家族。在这个家族中，真绥螨属是最大的属之一。该属物种具有广泛的取食行为，其食物包括螨类和花粉。一些研究已经证明某些真绥螨属物种具有控制害螨的潜力。文献中提到康氏真绥螨（Chant）可能对防治番茄锈螨，即番茄刺皮瘿螨（Tryon）（瘿螨科）有用。其他几种美洲物种在形态上与康氏真绥螨相似；对这些物种的形态变异了解甚少。本研究的目的是对康氏真绥螨以及世界上与其最相似的物种进行分类学重新评估。提供了本研究中所采集物种的测量数据以及区分该类群物种的分类检索表。形态学评估证实，弗氏真绥螨（Denmark & Muma）是康氏真绥螨的次异名，并确定卡氏真绥螨（De Leon）也是康氏真绥螨的次异名，霍氏真绥螨（De Leon）和巴西真绥螨（El-Banhawy）是中膜真绥螨（Dean）的次异名，以及活跃真绥螨（Chant & Baker）并非如之前所认为的那样是果食真绥螨（Gonzalez & Schuster）的次异名。
