Treatment

Himalanura draconis sp. nov.

( Figs 3P View FIGURE 3 , 6 View FIGURE 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 View Materials ]. GoogleMaps

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 View FIGURE 6 , 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 View FIGURE 3 ).

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 vesicle. 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 View FIGURE 47 ). 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 View FIGURE 47 2 View FIGURE 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 View FIGURE 47 ). 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 View FIGURE 47 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 View FIGURE 47 ).

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.
