An oribatid mite species found infesting the farmed eels Anguilla australis and A. dieffenbachii (Anguillidae) in New Zealand was identified as Hydrozetes lemnae in the family Hydrozetidae (Acari: Sacoptiformes). All post larval stages have been detected and identified. The potential significance of the mites to the farmed eels is discussed.

One new genus and six new species of eriophyoid mite from Mountain Trusmadi, Malaysia are described and illustrated. They are Isoannulus morrisianaesp. nov. on Diospyros morrisiana (Ebenaceae), Abacarus bicolorussp. nov. on Lespedeza bicolor (Leguminosae), Parneometaculus persicariaegen. nov. & sp. nov. on Persicaria chinensis (Polygonaceae), Shevtchenkella miscanthissp. nov. on Miscanthus floridulus (Poaceae), Davisella nitidissp. nov. on Artocarpus nitidus subsp. lingnanensis (Moraceae), and Vimola blastissp. nov. on Blastus cochinchinensis (Melastomataceae).

Two new pteronyssid feather mite species are described from passeriform birds in China: Pteroherpus pomatorhinaesp. nov. from the Streak-breasted Scimitar-babbler Pomatorhinus ruficollis Hodgson (Passeriformes, Timaliidae), and Pteroherpus chinensissp. nov. from the Collared Finchbill Spizixos semitorques Swinhoe (Passeriformes, Pycnonotidae). Pteroherpus pomatorhinaesp. nov. belongs to the diploplax species group. The males of Pteroherpus pomatorhinaesp. nov. have the prodorsal shield elongated, the opisthosoma narrowed to posterior end, the opisthosomal lobes slightly elongated, and two pairs of small additional sclerites (one dorsally, between prodorsal and hysteronotal shield, and one ventrally posterior to genital apparatus). The females of Pteroherpus pomatorhinaesp. nov. have a pair of anterior hysteronotal sclerites, a central sclerite, a pair of lateral opisthosomal sclerites partially split into lateral and inner fragments and a pair of pygidial sclerites. The central sclerite has almost parallel lateral margins and concave posterior margin, and the posterior ends of the fragments of opisthosomal shields are connected by a thick bridge. Pteroherpus chinensissp. nov. belongs to the hoplophorus species group. The males of Pteroherpus chinensissp. nov. have prodorsal shield slightly longer than wide, the opisthosoma moderately narrowed to posterior end, the opisthosomal lobes wide and short and the adanal shield with irregular form. The females of Pteroherpus chinensissp. nov. have the anterior hysteronotal sclerite fused with the prodorsal shield into a complex shield, a central sclerite, a pair of lateral opisthosomal sclerites and a pair of pygidial sclerites. The central sclerite is well delimited, and shaped as a longitudinal plate, slightly narrower posteriorly, with slightly convex anterior margin, concave lateral margins, and strongly convex posterior end.

New material of water mites (Acari: Hydrachnidia) from the Uttarakhand State of India is reported, including a new species, Kongsbergia indicasp.nov. (Aturidae), and new records of the species Sperchon garhwalensis Kumar, Kumar & Pešić, 2007, Sperchon indicus Kumar, Kumar & Pešić, 2007, and Atractides indicusPešić & Smit, 2007. Moreover, in the light of the newly discovered male of Torrenticola turkestanica (Sokolow, 1926), populations from South Korea and Thailand formerly assigned to the latter species are here attributed to two new species, i.e., T. wonchoelisp.nov. and T. rangareddyisp.nov., respectively.

A new genus and species of termitophilous pygmephorid mites, Pseudoluciaphorus tuberosusgen. nov. and sp. nov. (Acari: Prostigmata: Pygmephoridae), associated with termites, Microcerotermes parvus (Haviland) (Isoptera: Termitidae) are described from South Africa. Luciaphorus perniciosus Rack is recorded from Africa for the first time. Images of phoretic females of L. perniciosus phoretic on workers and soldiers of Microcerotermes parvus are provided.

A new species of Zeasuctobelba (Oribatida, Suctobelbidae) is described from a moss Sphagnum magellanicum in swamp in southern Chile. Zeasuctobelba processasp. nov. differs from all species of the genus by the presence of a median process on the anterior margin of the ventral plate (anterior part of epimere I), lateral sides of prodorsum with one pair of strong triangular processes and by bothridial setae having long setiform apices and long cilia. Revised generic diagnosis, identification key and data on distribution of known species of Zeasuctobelba are presented. Zeasuctobelba nodosaHammer, 1966 and Z. arcuataHammer, 1968 are excluded from Zeasuctobelba.

Two new species of the tribe Colomerini from China are described and illustrated. These species are Isoannulus baishaensissp. nov. collected from Combretum indicum (L.) DeFilipps (Combretaceae), and Gammaphytoptus diaoluoshanensissp. nov. found on Bauhinia sp. (Leguminosae). All are vagrants causing no damage to the host plants.

The genus Apoplophora (Oribatida, Apoplophoridae) was represented by three species in China prior to this work. In this study, a new species, Apoplophora filiformissp. nov., is described from Tongguling, Hainan Island. New localities of known species from China are presented. An updated key to world species of the genus is provided to facilitate the further study on this group.

Four new species are described: Schoutedenichia asirensissp. nov.,Schoutedenichia saudisp. nov.,Microtrombicula microscutasp. nov., and Microtrombicula muhaylensissp. nov. Fifteen species—Gahrliepia lawrenceiJadin and Vercammen-Grandjean, 1952, Schoengastiella wansoni Wolfs and Vercammen-Grandjean, Walchia parvula Schluger, Ascoschoengastia browni Taufflieb, Mouchet and Courtois, Helenicula lukshumiae Nadchatram and Traub, Schoutedenichia thracica Kolebinova, Schoutedenichia zarudnyi Kudryashova, Ericotrombidium caucasicum (Schluger), Ericotrombidium galliardi (Vercammen-Grandjean and Taufflieb), Ericotrombidium kazeruni (Kudryashova), Microtrombicula centropi (Vercammen-Grandjean), Microtrombicula hoogstraali (Radford), Microtrombicula hyracis (Vercammen-Grandjean), Microtrombicula traubi (Muljarskaja and Verdieva), and Pentidionis agamae (André)—are for the first time recorded in Saudi Arabia and on new host species. Six of them are for the first time recorded outside their type localities and five were only known previously from the African continent.

A new Tetranycopsis species, Tetranycopsis vertesiensissp. n., is described from Central-Hungary on grasses (Poaceae) based on females. The new species differs from the previously described congeners in the length of dorsal setae, all setae (except v1 and v2) similar in shape and length and number of setae on femur of leg I (10), which is a unique character combination within the genus Tetranycopsis. The first Central-European record of the genus Mesobryobia is presented. Specimens of Mesobryobia terpoghossiani (Bagdasarian, 1959) were collected in two different places in Hungary.

Piroplasmic parasites such as Theileria and Babesia commonly infect important livestock animals, leading to economic losses in the livestock industry. These parasites are primarily transmitted by ticks found infesting livestock animals. In Malaysia, livestock diseases caused by tick-borne pathogens are still under-studied, even though tick infestations are common in many livestock farms. Here, we molecularly detect a Theileria sp. from Haemaphysalis bispinosa ticks infesting goats in a privately-owned farm in Perak, peninsular Malaysia. PCR was performed on the DNA extracted from ticks to determine the presence of piroplasms. Three ticks were found PCR-positive for piroplasms. Sequence analyses of partial 18S rRNA gene sequences revealed the presence of a Theileria species at 100% identity to Theileria luwenshuni. Our findings suggest the presence of T. luwenshuni, a highly pathogenic Theileria sp. to sheep and goats, in the small ruminant industry in Malaysia.
