The following taxa are recorded for the first time: for the Palaearctic-Superioropus huronmontanus (genus and species); for Russia-Pleuronectocelaeno japonica, Trichouropoda karawaiewi, Dendrolaelaps pini, Gamasellodes tatricus, Scutacarus palustris, Tarsonemus typographi, Heterotarsonemus lindquisti, Hemisarcoptes, Saproglyphus waldorfae, Naiadacarus, Schwiebea nesbitti, Histiostoma pini, and H. ovalis. Of them, 60 species were collected by catching beetles with pheromone traps and examining them for phoretic mites. We provide information on the current distribution, host association, and biology of these mites. In this article, we also discuss the following information, which we have documented: our biological observations of mites in the beetles' galleries, abundance of phoretic mites on hosts, as well as specific sites where they occur. To facilitate morphological diagnostics, common mite species were illustrated using a Scanning Electron Microscope (SEM), as well as light microscopy.

The predatory mite, Neoseiulus neoagrestis Khaustov and Döker (Acari: Phytoseiidae), recently described as new species for science, but seems to have a great potential to be used in biological control. In this study, as a first step to determine the optimum temperature (between three temperatures tested) for its mass rearing, we studied its biological characteristics and life table parameters fed on Tyrophagus putrescentiae (Schrank) (Acari: Acaridae) at three different temperatures (20, 25, and 30 °C) under laboratory conditions. Results show that immature development, oviposition period as well as reproductive potential of this predator are significantly vary depending on the temperature. The immature developmental times and adult longevity for females, are ranged between 5.42 to 10.42 days and 39.88 to 74.12 days, based on the temperature, respectively. Average total number of eggs laid by per female at 25 °C (62.29) and 30 °C (58.65) are more or less similar but higher than that determined at 20 °C (41.46). The highest net reproductive rate (R₀) is 29.066 (offspring/individual) at 25 °C. In addition, the highest intrinsic rate of natural increase (r) is 0.241 day^-1 at 30 °C. Furthermore, the highest finite rate of increase (λ = 1.272 day^-1), and the shortest mean generation time (T = 13.416 days) and doubling time (DT = 2.874 days) are also determined at 30 °C. Our results demonstrate that N. neoagrestis successfully completed immature development, and can survive and reproduce at all tested temperatures. Nevertheless, a series of biological characteristics of this predator are differentially affected by the temperature. Finally, 25 °C and 30 °C seems to be more suitable for mass rearing of this predator on T . putrescentiae. Further studies should be conducted to determine biological characteristics and life table parameters of N. neoagrestis on several important pests such as spider mites, whiteflies and thrips.

Two new species of the genus Flagellozetes (Oribatida, Galumnidae) – F. (Cosmogalumna) carinodentatus sp. n. and F. (C.) pseudoareticulatus sp. n. – are described from the bark of different trees in Vietnam. A comparative analysis of the F. (Cosmogalumna) group included species with neural ridges on the notogaster is presented.

A new species of the genus Scapheremaeus (Oribatida, Cymbaeremaeidae)—S. marati sp. nov.—was collected from bark of different trees in Cat Tien National Park, southern Vietnam, is described based on adult and juvenile instars. The identification keys to known adults of Scapheremaeus from the Oriental region, as well as to larvae and nymphs of known scapheremaeid species are presented.
