description
Redescription based on Australian material. Size. Length up to 0.9 mm excluding antennae (n = 7). Colour. Pattern as in Fig 2 J, some colour variations shown. Head. Antennal length 847 – 1020 μm, 2 – 3 times the length of the head; Ant IV with a bilobed apical vesicle. Relative lengths of Ant I / II / III / IV = 1.0 / 2.1 / 1.9 / 2.6. Four spinulate labral papillae or with some projections, four ciliated prelabral chaetae and 5,5,4 labral smooth chaetae. Lateral process of papilla E reaching at the papilla tip. Labial posterior row with MREL 1 L 2, R smaller than M; eight eyes, G and H similar in size to E and F. Thorax and abdomen. Ratio of lengths of Abd IV / III = 4 (n = 7). Trochanteral organ near of 22 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 % from the base and the most distal one minute. Dorsal tooth approximately at half distance between the base of unguis and internal pair of teeth. Unguiculus spike – like, with a smooth or external edge on leg III. Furcal length 636 μm (n = 7). Manubrial plate with 4 chaetae and 2 psp. Mucro with 2 teeth, subapical tooth in size similar to the apical one. Mucronal spine present. Macrochaetotaxy. Simplified formula: 3,1,0,3,2 / 2,3 / 2,2 / 1,2,1 / 0,2,3,2,2. Head chaetotaxy with H 1 area with An 2, An 3 a 1 and An 3, and as in Fig. 27 A, H 2 with A 5, S’ 0 Mc no present; H 4 with S 1, S 3 and S 4 i Mc, H 5 with Ps 2 and Ps 5. Thoracic chaetotaxy Area T 1 on Th II with 2 Mc (m 1 and m 2 i or m 2 present) (Fig. 27 B). Area T 2 on Th II with 3 Mc present (a 5, m 4 and m 4 i). Abdominal chaetotaxy Area A 1 on Abd II with 2 Mc as in Fig. 85 and area A 2 on Abd II with 2 Mc. Abd III with 1 Mc on areas A 3 and A 5, 2 Mc on area A 4 as in Fig. 27 C. Abd IV with 18 Mc (A 3 – A 6, B 4 – B 6, E 1 and C 2 a) sometimes a variation on Area A 7 on Abd IV 1 – 3 Mc. (Fig 27 D). Sensillary chaetotaxy S = 21 / 02293 and Ms = 10 / 101, similar position to E. nigrocincta.
discussion
Remarks. The characteristic colour may fade and only remain on the anterior part of Th II and on a distal part of the body. The only difference from the European E. multifasciata (cf. Jordana, 2012) is the presence of 3 Mc on H 4 in the head, but some Australian specimens are asymmetric in this character. This introduced species is the most widespread and abundant species of the genus in Australia. It has been misidentified as E. tenuicauda previously and with females of E. nigrocincta because of a similar colour. It is rarely found in native vegetation and nearly always in improved exotic grasses in pasture and on other open disturbed land.
