Tectopedial field incomplete. Two pairs of prodorsal tubercles present, medial prodorsal tubercles long, lateral prodorsal tubercles rounded. Lateral enantiophysis well developed. Notogaster (Figs 6a; 7; 8a, c). L/W of notogaster about 1.2. Anterior margin of notogaster round. Lateral notogastral condyle present, small and teeth-like, directed towards the lateral prodorsal tubercle. Ten pairs of notogastral setae setiform, slender at tip. Seta lm below level of la. Lyrifissure ip located between setae h 1 and p 1, ips located lateral to p 3, ih located anterior to ips. Opisthonotal gland opening located posterior to lyrifissure im. Epimeral and lateral podosomal regions (Figs 6b; 7; 8b, c). Epimeral setal formula: 3-1-3-3, all epimeral setae setiform, smooth, seta 4a inserted at post tip of epimeral plate IV. Discidium triangular. Anogenital region (Figs 6b; 7; 8b, c). Six pairs of genital setae setiform, smooth, g 1–4 inserted along inner margin of genital plate while g 5–6 inserted posteriorly, g 1 longer than the others, mutual distances g 5 – g 5 largest. One pair of aggenital, two pairs of anal (mutual distances an 1 – an 1 ≈ an 2 – an 2) and three pairs of adanal setae setiform, smooth. Adanal seta ad 1 in posterolateral, ad 2 in lateral (ad 2 – ad 2 nearly same level with iad–iad), ad 3 in anterolateral positions to anal opening. Mutual distances ag–ag> ad 2 – ad 2 ≈ ad 3 – ad 3> ad 1 – ad 1. Adanal lyrifissure located longitudinal and close to anal aperture, below level of anterior margin of anal opening. Gnathosoma (Fig 9). Subcapitulum size: 88 × 49. Subcapitular setae (h, m 20–22; a 25) setiform, smooth. Chelicera (length: 90) attenuate-edentate, with smooth seta cha only; movable digit a little longer than immovable digit, without teeth. Palp (length: 70) with setal formula: 0-2-1-2-8 (+ω); solenidion pressed to the surface of palp tarsus. Legs (Table 1). Generally similar as A. (A.) polita sp. nov. Claw of each leg strong and smooth. Formulas of leg setation and solenidia (Table 1): I (1-5-2-4-20) [1-2-2], II (1-5-2-4-16) [1-1-2], III (2-3-1-3-15) [1-1-0], IV (1- 2-2-3-12) [0-1-0]. Setae p eupathidial on leg I and thorn-like on legs II–IV seta s on tarsus I eupathidial and located between u and a. Material examined Holotype: female (ZLH-21-051): China, Anhui Province, Jinzhai County, Tiantangzhai Town, Yezhulin, 31°6′52″N, 115°45′50″E, 1450 m a.s.l., in soil under tree and bamboo, 4.VIII.2021. Paratypes: one male (ZLH-21-051): same as holotype; one male (ZLH-21-041): China, Anhui Province, Jinzhai County, Tiantangzhai Town, Baima Canyon, 31°8′57″N, 115°46′0″E, 756 m a.s.l., in soil under coniferous forest, 3.VIII.2021. All specimens were collected by Lihao Zheng. Type deposition The type specimens are deposited in the collection of IZAS. Etymology The specific epithet “ subiasi ” is named after the late Prof. Luis S. Subías for his great contribution to the taxonomy of Oribatida. Remarks The new species is most similar with A. (A.). vietnamensis Ermilov & Anichkin, 2014 in the presence of the lateral notogastral condyle and shape of bothridial seta (spindle-form, with long stalk, shorter head and setiform tip). But it differs from the latter by: three pairs of rostral teeth in total (vs. four pairs of rostral teeth in total), tectopedial fields wide and smooth (vs. tectopedial fields absent), rostral region without oval foveolae (vs. rostral region with one pair of oval foveolae).
