ABSTRACT.– A new species of sphaerolichid mite, Sphaerolichus lekprayoonae n. sp. (Acari: Sphaerolichida: Sphaerolichidae), is described and illustrated based on adult specimens collected from leaf-litter in tropical forests in Thailand. It is distinguished from other known species of Sphaerolichus by the unique presence of prodorsal apodemes, hype...

The first representatives of tarsocheylid mites (Acari, Heterostigmata) from Thailand, Hoplocheylus longisetosus sp. nov. and Hoplocheylus nudis sp. nov., collected from sandy soil of the coastal grassland area, are described and illustrated.

A new species of the predatory mite family Caeculidae, N. orientalis sp. nov., is described and illustrated, based on adult and all active immature instars from moss and forest litter of various localities in Thailand. Neocaeculus orientalis sp. nov. differs from its congeners in uniquely having the adult femur I divided but femora II-IV entire, ad...

We describe a new species of pseudocheylid mite in the genus Anoplocheylus Berlese, Anoplocheylus corticicola sp. nov., based on adults and immatures, and record the occurrence of A. aegypticus Baker & Atyeo, 1964 from Thailand. Immature (deutonymphal) dimorphism in A. corticicola sp. nov. is reported for the first time in Pseudocheylidae. The disc...

Nanohystrix hammerae n. gen., n. sp.-proposed on the basis of numerous adults and a few juveniles-is a new oribatid mite of the infraorder Enarthronota that appears to be phylogenetically relictual and endemic to northern New Zealand, in habitats ranging from native shrublands to native and semi-native forests. With an adult body length of 1-1.2 mm...

A new genus and species of enarthronote oribatid mite, Psammochthonius kethleyi n.g., n. sp., is described and illustrated based on adult and immature specimens collected from coastal sandy soil in Thailand (Phangnga), Brazil (SAo Paulo) and the U.S.A. (Mississippi). Analysis shows that it is a member of Hypochthonioidea, but not of any named famil...

Two new species of the prostigmatic mite genus Adamystis Cunliffe, 1957-A. theroni sp. nov. and A. ueckermanni sp. nov.-from Fars province, Iran are described and illustrated based on female specimens collected from soil, humus and leaf litter under oak trees (Quercus brantii Lindl, 1840). Adamystis theroni sp. nov. differs from its congeners in ha...

A new species of sphaerolichid mite, Sphaerolichus lekprayoonae n. sp. (Acari: Sphaerolichida: Sphaerolichidae), is described and illustrated based on adult specimens collected from leaf-litter in tropical forests in Thailand. It is distinguished from other known species of Sphaerolichus by the unique presence of prodorsal apodemes, hypertrophied s...

The oribatid mite genus Nothrolohmannia Balogh is reported for the first time from mainland Asia, represented by two new species from Thailand: N. thailandica sp. nov. and N. flagellata sp. nov. They are described and illustrated based on adult specimens from leaf litter of seasonal dry tropical forests. Nothrolohmannia thailandica sp. nov. is reco...

Two new species of the prostigmatic mite genus Adamystis Cunliffe, 1957—A. theroni sp. nov. and A. ueckermanni sp. nov.—from Fars province, Iran are described and illustrated based on female specimens collected from soil, humus and leaf litter under oak trees (Quercus brantii Lindl, 1840). Adamystis theroni sp. nov. differs from its congeners in ha...

Two new species of oribatid mite subgenus Phyllolohmannia of Mixacarus (Acari: Oribatida: Lohmanniidae), Mixacarus (Phyllolohmannia) tenasserimensisn. sp. and Mixacarus (P.) variatan. sp., are described and illustrated from Thailand based on adult and immature instars collected from the leaf-litter of dry evergreen forests. An identification key to...

Two new species of oribatid mites, Temburongia similanensis sp. nov. (Synichotritiidae) and Austrophthiracarus trapezoids sp. nov. (Phthiracaridae), are described based on adult specimens from leaf litter on Similan Islands. Thailand. Temburongia similanensis sp. nov. differs from T. patoi Mahunka, 1990 in having simple prodorsal and notogastral se...

Two new species of the oribatid mite family Protoplophoridae (Acari: Oribatida), Arthrhoplophora adjacentis sp. nov. and Protoplophora takensis sp. nov., collected from leaf litter of dry evergreen forest, are described and illustrated from Thailand. Arthrhoplophora adjacentis sp. nov. is unique in having the long ciliated rostral setae which are c...

A new species of soil prostigmatic mites, Adamystis thailandensis sp. nov. (Acari: Adamystidae) is described based on adult and immature specimens collected from leaf litter and upper soil layer in a coastal forest in southern Thailand. It differs from its congeners by the presence of a densely striated idiosomal shield and the presence of lens-lik...

The enarthronote oribatid mite genus Phyllochthonius Travé, 1967 (Acari: Oribatida: Phyllochthoniidae) is recorded from Thailand for the first time. Two new species, Phyllochthonius ovatosetosus n. sp. collected from sandy soil in a riparian habitat and Phyllochthonius peniculus n. sp. collected from leaf-litter on the forest floor, are described b...

Two new species of predatory mites in the family Cheyletidae (Acari: Prostigmata), Mexecheles thailandensis n. sp.collected from tree bark infested by scolytid beetles and Samsinakia charanasriae n. sp. from soil and leaf-litter, are described and illustrated from Thailand. Keys to species of Mexecheles and Samsinakia are also provided.

Sinocallipus thai sp.n, is described from Saraburi Province, Thailand. This is the second species in the suborder Sinocallipodidea Shear, 2000, hitherto known only from S. simplipodicus, discovered in a cave in Yunnan, southern China. Although there are just a few differences in the structure of the gonopods, the new species can be easily distingui...

Oribatid mites are a group of soil dwelling arthropods. The short-term effect of an atrazine herbicide on them was studied in a mango orchard, which had never been treated with atrazine. The experiment design was a randomized completed block (RBC) with three replications. The soil samples were randomly collected from two atrazine-treated plots (at...
