Here we report the detection of Candidatus Rickettsia tarasevichiae from a tick collected from a human patient through molecular method. We amplified and sequenced rickettsial citrate synthase encoding gene (gltA), 190_kDa outer protein gene (ompA), and 120_kDa outer protein gene (ompB). Sequencing results showed that its gltA gene and ompA gene shared 100% and 96% sequence similarities with Candidatus R. tarasevichiae gltAgene (GenBank: KT899085) and R. canadensis ompB gene (GenBank: KT899079), respectively. On the other hand, DNA extracted from the patient's serum shared 98% sequence similarities with R. japonica (GenBank: AF123713). Thus, we identified Candidatus R. tarasevichiae from tick and R. japonica from patient serum in this study.

During a faunistic survey on eriophyoid mites associated with weeds in Golestan province of Iran, four eriophyoid species were collected. A new species, Aculops hyperisaemumsp. nov., was found on Hypericum androsaemum L. (Hypericaceae) and herein described and illustrated. Paraphytoptus paradoxusNalepa, 1896, Aceria lamii (Liro, 1943) and Aceria verbenacaede Lillo et al., 2017, were found respectively on Artemisia absinthium L. (Asteraceae), Lamium album L. and Salvia nemorosa L. (Lamiaceae) and are reported for the first time in Iran. Aculops hyperisaemumsp. nov. and A. lamii were vagrant on the underside of the leaves of their host plants and no symptoms were detected. Aceria lamii is redescribed using modern microscopy and terminology. Paraphytoptus paradoxus was vagrant on the leaf underside and caused discoloration of the leaves; this is the first record of Paraphytoptus from Iran. Aceria verbenacae induced erinea on leaves, petioles, stems and flowers on a new host plant species.

A new oribatid mite subgenus, Ramusella (Dosangoppia) subgen. nov. (Oribatida, Oppiidae), with Ramusella (Dosangoppia) bochkovi sp. nov. as type species, is described based on adults phoretic on beetles of Ceratophyus polyceros (Coleoptera, Geotrupidae) collected from southwest of Russia. It is distinguished from other oppiid taxa by the presence of modified leg claws I and II (thick, specifically curved) performing the function of attachment to setae of the beetle hosts at a phoresy.

Diagnosis and description of a new mite species Saniosulus deliquus sp. nov. (Acari: Eupalopsellidae) are presented with illustrations based on specimens collected from Erzincan and Pülümür Valley, Turkey. An updated key to Saniosulus species is provided.

The effects of six ambient temperatures (15, 20, 25, 30, 35 and 37.5°C) on life table parameters of Tetranychuskanzawai Kishida (Tetranychidae) were studied under laboratory conditions on soybean (Glycine max (L.) Merrill). Total immature developmental time of females at the above-mentioned temperatures was 28.55, 16.34, 9.01, 6.96, 5.56 and 5.65 days, respectively. A linear and two nonlinear models of Lactin and SSI were fitted to developmental rate of immature stages of T. kanzawai to predict the developmental rate as a function of temperature, as well as to estimate the thermal constant (k) and critical temperatures. The estimated k for total immature developmental time of females and males was 134.58 and 126.74 DD, respectively. The estimated T_opt and T_max by Lactin model for overall immature stages were 36.20 and 40.70°C, respectively. Intrinsic optimum temperature (T_Φ) and T₁) (T_opt) by SSI model for total immature stages was estimated to be 23.23 and 35.71°C, respectively. Also the estimated T_L and T_h of SSI model for overall immature stage were 09.21 and 38.46°C, respectively. The longest and shortest adult longevity was observed at 15°C (60.63 days), and 37.5°C (7.34 days), respectively. Mated females laid highest and lowest eggs at 25°C (237.96 eggs) and 37.5°C (30.54 eggs), respectively. The r_m values ranged from 0.356 day^-1 at 30°C to 0.089 day^-1at 15°C. The highest value of R₀ was 163.55 offspring female^-1 at 25°C. The presented information in this study provided new perspective to better management of T. kanzawai on apple trees in Iran.

Two new species of oribatid mite family Phthiracaridae, Plonaphacarus projectus sp. nov. and Plonaphacarus spiniformis sp. nov., are described from China. New data about Plonaphacarus kugohi (Aoki, 1959) and an updated identification key to all known Chinese species of the genus Plonaphacarus are provided.

Two new species, Eryngiopus rezaiyeiensissp. nov. and Parastigmaeus urmiaensissp. nov. of the family Stigmaeidae (Acari: Trombidiformes), are described and illustrated based on female and deutonymph specimens collected from Northwest Iran. A modified and updated table of diagnostic characters of the species of Eryngiopus, is also provided.

Lassenia japonica Haitlinger, Negm & Šundić sp. nov. with fnCx 1-1-2 is described and illustrated from larvae collected from Maesa japonica (Primulaceae) in Japan. It is the first species of Tanaupodidae found in Japan. A key to Lassenia (larvae) of the world is provided.

The objective of the study was to investigate the efficacy of cypermethrin, chlorpyrifos and piperonyl butoxide based pour-on and spray acaricides for the control of Rhipicephalus microplus in a naturally infested cattle herd. Fifty eight male Brangus cattle in the rearing phase were divided into treated (28) and untreated (30) groups. The treated group was subdivided in treated with a pour-on acaricide (13) and treated with a spray acaricide (15). Every 18 days, tick counts, acaricide treatment, weighing and clinical observation were performed on the animals, totaling four evaluation time points. The adult immersion tests were used for in vitro analysis of the study population to different chemical bases was assessed for primary results. Tick counts were separately compared between groups at each time point using the Kruskal-Wallis and Wilcoxon tests. Significantly fewer number of ticks were observed on the treated group compared to control group and also on the sprayed subgroup compared to pour-on subgroup (p<0.05). Our results indicate that the chemical treatment evaluated directly affects the number of ticks parasitizing animals and that products employing a spray application method may be more effective in controlling cattle ticks.

The present study is based on oribatid mite material (Acari, Oribatida) collected from soil of Kaaimansgat estuary, Wilderness, Western Cape, South Africa in 2018. A list of identified taxa, including 41 species from 34 genera and 23 families, is presented; of these, nine species, three genera and one family are recorded in South Africa for the first time. Two new species belonging to the family Oppiidae are described: Kokoppia kaaimansensis sp. nov. differs from Kokoppia dudichi (Balogh, 1982) by the larger body size, the medium sized lamellar and interlamellar setae, the presence of muscle sigillae in the interlamellar region and the distinctly semi-oval epimeral borders IV and the absence of notogastral setae c; Paroppia neethlingisp. nov. differs from other species of the genus by the localization of adanal lyrifissures in a direct apoanal position and the absence of epimeral borders IV. Revised generic diagnoses and identification keys to the known species of Kokoppiaand Paroppia are presented.

A new species of Scutacaridae (Acari: Heterostigmatina: Pygmephoroidea) associated with Reticulitermes banyulensis Clément, 1978 termites (Isoptera: Rhinotermitidae) is described from Spain. By rearing the mites in laboratory cultures, all life stages (larva, female and male) of Imparipes clementis Baumann sp. nov. were available for descriptions, and information on the mites' biology could be provided. As the new species strongly resembles I. adleri Delfinado & Baker, 1976, a multivariate morphometric analysis was performed to further support its species status.

Multidentorhodacarus tocantinensis sp. nov. is described based on the morphology of adult females collected from litter and soil in the Cerrado biome of the State of Tocantins, north of Brazil. The holotype and paratypes of M. squamosus Karg, 2000 were examined, given that this species was also found in this study, and complementary morphological information about it is provided. A key for the separation of females of the 20 recognizable world species of Multidentorhodacarus Karg is provided.
