A new water mite Sperchon (Hispidosperhcon) beckeri Bader and Sepasgosarian, 1984 is recorded for the first time from Elazığ province, Turkey. This species is characterized by the P-2 with long finger-shaped ventral projection and P-4 with well-developed ventral tubercles.

In the present paper, zerconid mites of the genus Prozercon were collected from the Dilek Peninsula-Büyük Menderes Delta National Park, Didim County, Aydın Province (western Turkey). After identification processes, three Prozercon species were found in the research area, among them, P. didimensis sp. nov., was described and illustrated as a new species for the science. Also, altitude and habitat preferences of the species were given and discussed.

Rotundabaloghia (Rotundabaloghia) dogani sp. nov. is described based on three females and one male collected from soil in Tai Po Kau Nature Reserve, in Hong Kong. The new species differs from the other species from the subgenus Rotundabaloghia in the shape and length of the ventral setae.

: An isolated population of the Eldari tick Ixodes eldaricus Dzhaparidze was studied in the southernmost part
of the tick range (western surroundings of Jerusalem, Israel). Unfed adult and nymphal ticks were active from November
through April. Ticks could be collected by flagging only from the grass just above the earth. A bimodal activity pattern
was observed for adults with a decline in January characterized by the lowest air temperatures. Nymphal ticks had smaller size of their scutum as compared with specimens from the main part of the range. No mating adults were found during
survey but when placed in a tube, males and females were immediately observed in the mating position. No tendency to
attack humans or attach to them were registered in the field or in laboratory experiments. While having no apparent
epidemiological significance, I. eldaricus deserves attention because of its possible role in epizootiology of rickettsial
infections, which are common in the area of the survey.

House dust mites play an important role in causing various allergic disorders. Many factors like temperature, humidity as well as different microclimatic conditions may influence mite growth. The aim of this study was to analyse the mite fauna of Kolkata, West Bengal, India. House dust was collected from 20 selected houses located in and around Kolkata from January 2017 to December 2017. House dust samples were processed following the flotation technique and house dust mites were isolated from all the samples surveyed. A total of 51 species belonging to 34 genera and 17 families were isolated from positive samples. Dermatophagoides pteronyssinus, Blomia tropicalis and Cheyletus malaccensis were present in all positive samples. Most abundant mite in house dust was Dermatophagoides pteronyssinus, constitute 47% of the mites collected from dust samples. Amblyseius longispinosus was first time reported from Indian house dust.

Leonardiella pappi sp. nov. is described based on six females and two males collected from soil under Machilus sp., in Tai Po Kau Nature Reserve, in Hong Kong. The new species differs from the other species from the congeners in the shape of dorsal and ventral setae and dorsal and ventral sculptural pattern. A new diagnosis to the genus Leonardiella and a new catalog to all known species are given.

While performing a faunistic study on the superfamily Raphignathoidea of northwestern Iran, north parts of east Azerbaijan and southwest parts of west Azerbaijan provinces during 2016-2018, a total number of 40 species in 13 genera belonging to the superfamily were collected and identified. Among them, four species: Stigmaeus luxtoni Wood, 1981; Ledermuelleriopsis sezeki Doğan, 2004; Eustigmaeus gulingensis Hu and Chen, 1996 and Molothrognathus kamili Doğan, 2003 have been recorded for the first time from Iran.

Species diversity of zerconid mites was investigated in Buharkent, Karacasu and Kuyucak counties of Aydın province during February 2019 until February 2020. Seven species of the family Zerconidae were found in the research area, two of which belong to the genus Prozercon and remaining five species belong to the genus Zercon. A new species, Z. karacasuensis sp. nov., was collected from pine habitats (Pinus sp.) and described. In addition, altitute and habitat preferences of all zerconid mites collected from the research area, were given.

Chitin is the most abundant structural biopolymer after cellulose in terrestrial ecosystems. Until now, chitin isolation in powder or granule form has been carried out from many macro living groups (Arthropoda, Crustacea, Mollusca etc.). However, studies on chitin characterization of microscopic organisms have remained limited. In this study, three dimensional (3D) chitin extraction was performed for the first time from Trachytes pauperior (Berlese), a mite species. The obtained chitin was observed by light microscopy and characterized by FT-IR, and SEM analysis. Our findings suggest that chitin, which was obtained in high purity and constitutes a large part of the organism's body structure, could be a potential source for future studies.

This study was carried out in Madurai district, Tamil Nadu State, South India. Ticks were collected from cows, dogs, goats, cats, and fowls. The overall percentage of tick infestation in these domestic animals was 21.90%. The following ticks were identified: Amblyomma integrum, Haemaphysalis bispinosa, Haemaphysalis paraturturis, Haemaphysalis turturis, Haemaphysalis intermedia, Haemaphysalis spinigera, Hyalomma anatolicum, Hyalomma brevipunctata, Hyalomma kumari, Rhipicephalus turanicus, Rhipicephalus haemaphysaloides and Rhipicephalus sanguineus. The predominant species recorded from these areas is R. sanguineus (27.03%) followed by both R (B.) microplus (24.12%) and R. (B.) decoloratus (18.82%). The maximum tick infestation rate was recorded in animals from rural areas (25.67%), followed by semi-urban (21.66%) and urban (16.05%) areas. This study proved the predominance of hard ticks as parasites on domestic animals and will help the public health personnel to understand the ground-level situation and to take up necessary control measures to prevent tick-borne diseases.
