Dorsally whitish yellowish with some dark blue bands in anterior and lateral parts of Th II (sometimes with a posterior band), Lateral bands on Th III, Abd I and Abd II, Abd III with lateral longitudinal stripes and a posterior band with or without a posterior triangular central spot, Abd IV with lateral, transverse irregular bands and a narrow stripe on posterior edge. Abd V and VI with lateral spots (Figs 1A, 4A). Body some specimens very similar in colour to E. varia. Head. The apical bulb of antennal segment IV bilobed. The labral papillae spinulate with one or two spines. Prelabral and labral chaetae 4/554. Prelabral chaetae clearly ciliated, labral chaetae smooth. Labial chaetae with MREL 1 L 2 Ciliated chaetae, R smaller than M. External labial process of papilla E reaching at the papilla end. Eyes G and H small and subequal. Ant / head=2.55 (n=7). Ratio Ant I:II:III:IV=1:2.3:2.0:2.43. Thorax and abdomen. Trochanteral organ with 17–20 smooth and spiniform chaetae. Unguis (Figs 7 A–B) with 4 inner teeth; paired teeth located approximately 29% (n=12) of inner unguis length, dorsal tooth basal. Two clear unpaired teeth on the internal edge of the unguis, first one at 66% on unguis 1 and 2, 75% of the basis of unguis 3, unguiculus long in leg 3 and shorter in leg 1, on both legs truncate and with a smooth external edge. Tenent hair expanded distally and longer than the unguis. Manubrial plate with 4 chaetae and 2 pseudopores. Mucro normal. Not ringed part of dens 2 times the mucro. Chaetotaxy. Dorsal head chaetotaxy at figure 7D; Mc An’ 0, A 6, A 7, S’ 0, S 1, always absent, S 0, S 2, S 4i, S 4 and S 5 present (S 4i present or absent); M 2 and M 4 present; Ps 2 absent, Ps 5 always present. Thoracic chaetotaxy with one Mc (m 1) on T1 area on Th II, T2 area with Mc a 5 and m 4 (Fig. 7E). Abdominal chaetotaxy reduced.Abd II with a 2 present only in three specimens from 11, Mc a 3 absent, m 3 and m 3e Mc present Abd III with m 3 (Fig. 7G). Abd IV with 12 central and posterior Mc A 3, A 5 –A 6, B 5 –B 6 and E 1 (Fig. 7H). Mucro with 16 µ (n=7) as Figure 7C. The chaetotaxy formula: 3,1,0,2(1),1a/1,2/0(1),2/0,0,1/0,2,0,2,2. Trichobothria on Abd IV at T2 and T6 location (0101). Measurements: Ant I–IV 117, 264, 233, and 272 µm respectively. Abd IV/III=4 (n=7). Remarks. A number of specimens incorrectly labelled as Entomobrya varia from different localities were similar in chaetotaxy and were found to be this new species. The new species is common in high altitude locations in northeast Queensland with some material from Nothofagus rainforest at Styx River in northern NSW. Its colour is similar to that of Type II E. varia Schött, 1917 but it has a truncate unguiculus on all legs, which separates it from Entomobrya varia. It is also similar to E. peregrina sp. nov. in that they both have a simplified chaetotaxic formula in some respects. The following Table separates the three species by 12 characters as well as by the colour difference. 1=presence; 0= absence; Acu = acuminate; LP=labral papilla; mult = multispinate, tria = triangular; se = serrate; sm = smooth; Tru = truncate; A= E. additae; P= E. peregrina, V= E. varia. Differences A/P=8; A/V=8 Characters; P/V=9 Characters Very few Entomobrya have the truncate unguiculus, a character that is usually associated with halophilic habits. Etymology. The species name signifies yet another new species in the genus.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
