Gorgan, is a city in northern Iran where its moderate and humid climate and fertile soil provides an appropriate condition for various arthropods and crops. Although, species diversity is relatively lower in agricultural systems than pristine ecosystems, several soil mite populations are successfully adapted to both tilled and untilled lands. Following a faunistic study of heterostigmatic mites (Acari: Prostigmata: Heterostigmatina) in dry rice cultivations in some areas of Gorgan, eight species from six genera of five families were collected and identified. For the first time we report six species for Iranian arthropod fauna as well as several new host associations. Finally, we reviewed the world distribution of the recovered mites and further provided a key to Heterostigmatina of dry rice cultivations in Gorgan city.

Soil-dwelling Entomobryomorphan Collembola from the Northeast of Iran were sampled for the first time as part of a biodiversity surveying study with the aim of improving ecosystem conservation. Materials were obtained by sampling in three different ecosystems including forest, rangeland and agricultural fields between 2018 and 2019. The specimens were cleared using either Nesbitt’s fluid or lactic acid and permanent microscopic slides were prepared using Hoyer’s medium. As the result of this study, twenty-nine species belonging to twenty-two genera and five families of the order Entomobryomorpha were identified. Among them, two genera and eight species are recorded for the first time from Iran. The new records are Desoria trispinata (MacGillivray, 1896), Drepanosira hussi Neuherz, 1976, Heteromurtrella sp., Orchesella flavescens (Bourlet, 1839), Willowsia bartkei Stach, 1965, Agrenia sp., and Isotomiella gracilimucronata Rusek, 1981.

The Vidarbha region of India harbours a significant amount of biodiversity. However, the region still severely lacks data on lesser-known taxa such as odonates (dragonflies and damselflies). To partially fill in the knowledge gap on odonates, opportunistic surveys were conducted across nine sites in the Gondia district of Vidarbha between 2019 and 2021. In this report, the presence of 35 species from the study area, representing around 1/4^th of the total odonate diversity of Maharashtra is recorded. The results are indicative of the need for consistent sampling efforts in the region. Further systematic and long-term monitoring studies on odonates in Vidarbha Region are proposed.
