The definition of the mite genus Acalvolia is revised. A new species, Acalvolia americana, with conidia of Cladosporium sp. in its gut, intercepted on orange from the United States is described. Currently the genus consists of only one species, and the new species is distinguished from that species by having smooth supracoxal setae, longer setae sci (ratio sce: sci = 2.5–2.7), and longer dorsal...

The genus Oulenziella Fan and Zhang contains two species, O. bakeri (Hughes) longiseta Barbosa Moraes. This paper describes a third africana sp. n., collected from mango trees in Kenya, provides new record of for this country. We redefine the based on data provide an updated key to genera subfamily Oulenziinae (Acari: Astigmata: Winterschmidtiidae) species Oulenziella.

A new genus, Oulenziella, is proposed for Oulenzia bakeri (Hughes, 1962), a species originally collected on jute (Corchorus sp., Malvaceae) from India. Oulenziella bakeri (Hughes, 1962) comb. nov. is re-described. Oulenzia gossypii Meyer & Rodrigues, 1965 collected from Gossypium sp. in Mozambique is considered a junior synonym of Oulenziella bakeri. The new genus differs from Oulenzia in havin...

In a mutualistic relation between a potter wasp, Allodynerus delphinalis (Giraud) (Hymenoptera: Vespidae), and its specific parasitic mite, Ensliniella parasiticaVitzthum (Winterschmidtiidae), behaviour of the mite guarding the wasp and attacking their common natural enemy, Melittobia acasta (Walker) (Hymenoptera: Eulophidae), was examined. While mite attacks to M. acasta occurred by accidental...

A new salicyl lactone was detected from the unidentified Oulenzia sp. and its chemical structure was elucidated as 7-hydroxyphthalide (7-hydroxy-3H-isobenzofuran-1-one), based on its GC/MS and GC/FT-IR data and SiO2 column behavior. The compound was synthesized by NaBH4 reduction of 3-hydroxyphthalic anhydride. The GC/MS and GC/FT-IR spectra of the natural compound were consistent with those of...

Medwayella independencia, a new species of flea, is described from the tupaiid host Urogale everetti (Thomas) from Mindanao Island, Philippines. Several other species of fleas are also recorded from the Philippines including a single male of Lentistivalius philippinensis Hastriter and Bush, 2013 (previously known only from two males), the bat fleas Thaumapsylla breviceps orientalis Smit and Tha...

This is the second part of a survey mite lifespans initiated last year (Zhang & Fan 2021). series was launched to collect information on lifespan and related data across taxa, with aim stimulate more research both patterns mechanisms aging The first covered other life history for Oribatida, Winterschmidtiidae, Eriophyoidea, Tydeidae, Anystidae, Cheyletidae Blattisociidae provides surveys th...

This study was carried out between 2017-2019 to determine the mite species found in tea gardens of Rize province (Türkiye). During study, surveys 9 districts (Ardeşen, Çayeli, Derepazarı, Fındıklı, Güneysu, İyidere, Kalkandere, Centre and Pazar) were May September with random sampling method, corresponding plant's 1st, 2nd 3rd shoot period. Studies conducted 73 first period, 107 period 97 plant...
