Females can be distinguished from all oth- er described congeners by the distinctive, ‘eagle-like’ shape of the external epigyne (Fig. 52D). <b>Description.</b> <i>Holotype male</i>: Total length 0.98. Carapace 0.47 long, 0.40 wide. Abdomen 0.66 long, 0.48 wide. Leg I femur 0.35. Cephalothorax, abdominal sclerites, legs tan-yellow; abdomen with chequered dark-olive and tan-yellow pattern laterally and ventrally. Carapace raised anteriorly, not fused to sternum except around petiole; dorsal surface of pars cephalica slightly convex in lateral view. Eight eyes present on anterior margin of pars cephalica; AME 0.6x diameter of ALE; PME separated by half their own diameter. Chelicerae each with large, bulging anterior projection; promargin with three peg teeth. Legs relatively short (leg I femur-carapace ratio 0.74); distal, prolateral macroseta present on tibia I. Abdomen oval, covered with hair-like setae; dorsal scute large, covering most of dorsal surface of abdomen; lateral sclerotic strips absent. Pedipalpal patella with retrolaterally-directed, hooked lRPA, divergent distal apophysis and expanded distal region with ornate, ridged cuticular microstructure; tibia enlarged, with pointed posterior process; tegulum large, bulging posteriorly, with excavate ETR and large, divergent, fleshy distal conductor bearing prominent, retrolaterally-directed process; embolus short (length <5× width), spur-like, situated adjacent to base of conductor (Fig. 53). <i>Allotype female</i>: Total length 1.09. Carapace 0.49 long, 0.39 wide. Abdomen 0.74 long, 0.57 wide. Leg I femur 0.37. Cephalothorax, abdominal sclerites, legs tan-yellow; abdomen olive brown dorsally, with chequered dark-olive and tan-yellow pattern laterally and ventrally. Carapace raised anteriorly, not fused to sternum except around petiole; dorsal surface of pars cephalica slightly convex in lateral view. Eight eyes present on anterior margin of pars cephalica; AME 0.6x diameter of ALE; PME separated by slightly less than their own diameter. Chelicerae without bulging anterior projections; promargin without peg teeth. Legs relatively short (leg I femur-carapace ratio 0.76); macrosetae absent. Abdomen oval, covered with hair-like setae; dorsal scute and lateral sclerotic strips absent. Pedipalp entire, five-segmented. Epigyne heavily sclerotised externally, with distinctive ‘eagle-shaped’ morphology (Fig. 52D); spermathecae looped and twisted; insemination ducts curved and looped anteriorly; fertilisation ducts filiform (Fig. 51C). <b>Distribution.</b> Known from south-eastern Australia, in southern New South Wales, Victoria and Tasmania. <b>Remarks.</b> <i>Eterosonycha aquilina</i> is among the most distinctive of any Australian Textricellini, with an unmistakeable external epigyne (Fig. 52D) and male pedipalp (Fig. 53) morphology. It is common in moss and leaf litter in south-eastern Australia, and is one of the dominant micro-spiders in moss on Mount Donna Buang, in the Yarra Ranges of Victoria (M. Rix, pers. obs.). It can be found in sympatry with <i>E. alpina</i> at several localities (e.g. at Cuckoo Falls, Tasmania).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
