dc.description.abstractThe genus Agistemus Summers (Acari: Stigmaeidae) comprises predatory mites widely distributed in various agroecosystems. Agistemus manjilicus Khanjani, Hajizadeh & Zarei was described from Iran and differentiated from related species based on subtle morphological traits. However, a detailed comparison with A. mendozensis Simons reveals substantial overlap in diagnostic characters. In this study, we re-evaluated the taxonomic status of A. manjilicus through a comparative analysis of morphological characteristics, idiosomal dorsal setae measurements, diagnostic ratios, and leg chaetotaxy. Our results indicate that all distinguishing characters fall within the range of intraspecific variation of A. mendozensis. No consistent differences were found in key diagnostic traits such as dorsal setae morphology, diagnostic ratios, and leg chaetotaxy. Based on these findings, Agistemus manjilicus Khanjani, Hajizadeh & Zarei n. syn. is herein considered a junior subjective synonym of A. mendozensis Simons. This synonymy contributes to a more stable taxonomy within the genus and highlights the importance of comprehensive morphological comparisons in species delimitation.
