Himalanura draconis sp. nov. (Figs 3P, 6 F–G 48A–F) Holotype . Male, on slide, QLD, St George, - 28.0374°N, 148.5807°E, 200m asl, sweeping grasses, 12.v.1974, P.G leg. [SAMA 22670-01]. Paratypes. Two males subadult on the same slide, same collection data as holotype. Description. Size. Length up to 1.524 mm excluding antennae (n=3). Colour. Body colour pattern as in Fig 6F, ground colour clear brownish with lateral band blue violet lateral in Th II–Abd I. Blue violet almost the whole Abd II–IV, and the tip of Abd V and VI. Antennae blue/violet (Fig. 3P). Clothing. Body clothed with expanded chaetae like narrow scales (Fig, 6G, 47C) characteristic of the genus Himalanura . Head. Antennal length 778 μm (Holotype), 2.5 times the length of the head, Ant IV with a bilobed apical ves- icle. The relative length of Ant I / II / III / IV =1.0/3.5/2.5/2.9. 8 eyes, GH smaller in size than EF. Four labral papillae smooth (Fig. 47A). Four prelabral chaetae ciliated, 5,5,4 labral smooth chaetae. Lateral process of labial papilla E reaching the papilla tip. Posterior labial row with MREL 1 L 2, but only are present two ciliated chaetae, but the alveoli of chaetae R is small than of that M. Thorax and abdomen. Trochanteral organ with 8 spiny chaetae. Unguis with 4 teeth on internal edge: first pair at 50% distance from base of unguis, and 2 unpaired teeth, first one at 75% distance from the base and the most distal one minute. Dorsal tooth approximately near the internal pair of teeth. Unguiculus spike-like, with a serrated external edge on leg III. Furca length 583 μm (Holotype). Manubrial plate with 4 chaetae and two pseudopores. Mucro with 2 teeth, subapical tooth in size similar to the apical one. Mucronal spine present. Chaetotaxy. Simplified formula: 3,1,0,1,2/3,3/0,2/0,0,1/0,0,2,1,2. Head chaetotaxy with H1 area with An 2, An 3a1 and An 3, as in Fig. 47B, H 2 area with A 5, S’ 0 Mc absent, H4 area with S 1, S 3,S 4, S 5i and S 5 Mc; H5 with Ps 2 and Ps 5. Thorax with Area T1 on Th II with 3 Mc (m 1, m 2, and m 2i present) (Fig. 47D). Area T2 on Th II with 3 Mc present (a 5, m 4, and m 4i). Abdomen with Area A1 on Abd II without Mc as in Fig. 47E and area A2 on Abd II with 2 Mc. Abd III with 1 Mc on area A5, without Mc on area A3 and A4. Abd IV with 10 Mc on central area among bothriotricha (A 4, A 6, and B 4 –B 6). (Fig 47F). Measurements . Length ratio of Abd IV/III=3.38 (n=3). Remarks. The genus, Himalanura, is reported for the first time from Australia. Its chaetotaxy is unique for an Entomobrya and also for a Himalanura . In 2014 Baquero, Mandal & Jordana described a new species from India and gave a complete chaetotaxy for the genus. The genus until now was only known from Taimyr Peninsula (Russia), Yukutia and Magadan provinces (Russia) (Siberia) and high altitude sites in the Himalayas, India, Tadjikistan, Afghanistan and China (Jordana, 2012). Baquero et al . (2014) described it as having an artic-alpine disjunction. The Australian record extends its distribution around 7,000 km south east and to a low altitude habitat of arid grassland. This new species has the same chaetotaxy on Th II as H. maculae Yosii, 1971 and H. nuptsae Yosii, 1971, but the chaetotaxy of Abd II and III separate the three species: 0,2/0,0,1 Mc for the sp. nov. , 1,2,011 Mc for H. maculae and 2,7/0,2,2 Mc for H. nuptsae . Etymology. The species name is refers to the legend of the name’s locality (Saint George) near the sampling site. : Published as part of Jordana, Rafael & Greenslade, Penelope, 2020, Biogeographical and ecological insights from Australasian faunas: the megadiverse collembolan genus, Entomobrya (Entomobryidae), pp. 1-104 in Zootaxa 4770 (1) on pages 90-92, DOI: 10.11646/zootaxa.4770.1.1, http://zenodo.org/record/3797958 : {"references": ["Jordana, R.
