Entomobrya bioblitzi sp. nov.
(Figs 1D, 9 A–E)
Holotype. Male, NSW, Thredbo NP, alpine meadow, - 36.504722°S, 148.305556°E, 2037m asl, pitfall, January 2012, PG leg., [SAMA 22640].
Description. Size. Length 1.512 mm.
Colour. As indicated on label in having an orange head, as well as Abd V, VI (Fig. 1D).
Head. Eight eyes, G and H smaller than E–F. Antennae unknown. Labral papillae spinulate with three spines on each papilla (Fig. 9A). Labral chaetae with 4 prelabral and 5,5,4 chaetae, all smooth. Labial chaetae with MREL 1 L 2 ciliated, R smaller than M. External process of papilla E not reaching the papilla tip.
Thorax and abdomen. Length ratio of Abd IV/III=5.5. Tibiotarsus without differentiated chaetae, with exception of the presence of the smooth terminal chaetae on legs 3, characteristic for the genus. Trochanteral organ with 16-20 chaetae. Unguis with 4 teeth: paired at 50% of the basis, first unpaired at 75 % from the basis, dorsal and lateral teeth a little below the internal paired. Unguiculus acuminated, narrow, external lamella of leg 3 serrate. Tenent hair clavate, longer than unguis. Manubrial plate with 4 chaetae and 2 pseudopores. Mucro bidentate both teeth of similar size with mucronal basal spine. Mucro 15 micrometers and distal smooth portion of dens 2.5 times the mucro length.
Macrochaetotaxy. Simplified Mc formula: 4,1,0,1(2),1a/2,3/0,2/0,0,1/0,2,2,0,2. Head chaetotaxy (Fig. 9B) An 2, An 3a2, An 3a1, An 3 and A 5. M 2 and M 4 present as Mc. In sutural row present S 0, S 2, S 3, S 4i (present or absent), S 5i, S 5 and Ps 5 present. Thorax chaetotaxy: Th II chaetotaxy (Fig. 9C) T1 area with Mac m 1 and m 2, T2 area with Mc a 5, m 4, m 4i. Abdominal chaetotaxy (Fig. 9D): Abd II with m 3ep and m 3e, on Abd III m 3 Mc present; Abd IV (Fig. 9E) with Mc A 2, A 4, A 6, B 4, B 6, and E 1. Sensillary formula usual of Entomobrya . The bothriotricha on Abd IV in position T 2 and T 4 (0110).
Remarks. One specimen only was available. The colour of the fresh specimen was described on the slide. Taking into account only the chaetotaxy of the abdominal segments II and III 0,2 / 0,0,1, the only species with the same chaetotaxy of world Entomobrya are: E. assuta, E. boreensis sp. nov., E. clarki, E durrasensis sp. nov. and E. stirlingensis sp. nov. In the attached Table 4, the characters listed for E. bioblitzi easily separate it from the five species above. Table 4
Etymology. The species is named after the Bioblitz field expedition organised by NSW National Parks Officer, Ken Green in 2012.
