E-mail: [email protected] Abstract Three new species of Austrophthiracarus (Oribatida: Phthiracaridae) from New Zealand are described: Austrophthiracar- us matuku sp. nov. from the Bethells Matuku Reserve, Auckland, Austrophthiracarus notoporosus sp. nov. from the Tu- toko Bench, Fiordland and Austrophthiracarus karioi sp. nov. from the Mt. Karioi, Waikato. Holotype specimens are deposited in the New Zealand Arthropod Collection, Landcare Research and paratypes are deposited in the Northeast In- stitute of Geography and Agroecology, Chinese Academy of Sciences. Key words: Soil mites, Oribatida, Phthiracaridae, Austrophthiracarus, new species, New Zealand Introduction The family Phthiracaridae (Oribatida) consists of nearly 800 described species in 10 genera and is the largest family of ptyctimous mites (Niedbała 1994, Subías 2013). This paper is one of a series of recent efforts to increase our understanding of the phthiracarid fauna in New Zealand. Liu & Zhang (2013a) added a new species of Atropacarus (Atropacarus), Liu & Zhang (2013b) added two new species of Notophthiracarus, Liu & Zhang (2013c & d) added three new species of Austrophthiracarus, and Liu & Zhang (2013e) added two new species of Phrathicarus. This paper describes three more new species of Austrophthiracarus from New Zealand. Balogh and Mahunka (1978) proposed Austrophthiracarus with A. radiatus as type species. The members of this genus are mainly distinguished by median and lateral fields of prodorsum not fused; rostral setae inserted at distance from the end of rostrum; notogaster with 15 pairs of setae but often neotrichous; genital setae arranged in two rows, setae g close to or even above g, at least setae g and g far away from paraxial region; adanal setae far 6 4 6 7 away from paraxial margin, two setae (an and an) near the paraxial margin of ano-adanal plate; setae d on tibiae 1 2 IV short, coupled with solenidions (Niedbała 1994). Prior to this study, 42 species of Austrophthiracarus were known in the Australian Region, of which only seven species have been found in New Zealand (Niedbała 2012, Liu & Zhang 2013c, d). The purpose of this paper is to provide detailed descriptions and illustrations of three new species of this genus from New Zealand. This brings the total number of New Zealand species of the genus Austrophthiracarus to 10. Material and methods Measurements and descriptions are based on specimens mounted in temporary cavity slides that were studied using a light microscope equipped with a drawing attachment.
