On the synonymy between Agistemus manjilicus Khanjani, Hajizadeh & Zarei, 2015 and A. mendozensis Simons, 1967 (Acariformes: Stigmaeidae)
(Acarologia (Open Science in Acarology), 2026-06-26) Escobar Garcia, Hector Alonso; Ueckermann, Edward A.
The 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.
Preliminary survey, diversity, and population density of mites in banana, Musa AAA (Cavendish subgroup) cv. Williams in Peru

Banana is produced mainly by smallholder farmers and considered a staple food in many developing countries. This study aimed to evaluate the diversity and population densities of mites in plants of Musa AAA (Cavendish subgroup) cv. Williams in Peru. Mites were collected every fortnight for 14 months (February 2016 to March 2017) from a banana crop system located at the Universidad Nacional de Piura, northwestern Peru. The following species were found: Tetranychus abacae (Tetranychidae), Neoseiulus fallacoides and Euseius concordis (Phytoseiidae). This is the first report for T. abacae and N. fallacoides in Peru. The most abundant mite was T. abacae, which was found in all evaluations and had the lowest populations between June and August, corresponding to the winter time locally. Both N. fallacoides and E. concordis were found in very low numbers. Knowing mite species in banana plants is essential for a proper crop management, mainly for pest control strategies.
