Abstract
Pleuroseta monteithi sp. nov. urn:lsid:zoobank.org:act: 9321FA5F-A43E-4B05-8C88-E661260B9E23 Figs 5E, 10–11, 16B Etymology This species name is in honour of Dr Geoff Monteith, who collected the type specimens of this species as well as most of the other known specimens of Pleuroseta. Material examined Holotype AUSTRALIA • ♂; Queensland, Cape Tribulation, transect site 8; 16°05' S, 145°26' E; 18 Nov. 1998; G.B. Monteith leg.; dung trap, 6 am –6 pm; QMBA debu00160870. Paratype AUSTRALIA – Queensland • 1 ♂; same collection data as for holotype; DEBU. Description BODY (Fig. 10A). As described for P. ingens sp. nov., except as follows: length 3.7–3.8 mm. Frontal width 2.4–2.5 ×interfrontal height. Gena with 11–14 setulae. First postsutural pair of dorsocentral bristles separated by 9–10 rows of fine acrostichal setulae. Anepisternum with posterodorsal patch of 5–6 setae and 10–12 setulae. Wing pattern (Fig. 15B) slightly paler than in P. ingens. CS2 1.3×length of CS3. MALE ABDOMEN (Figs 5E, 10B–C, 11). S5 broad, subrectangular with large, triangular, posteromedial emargination, posterior surface of each lateral lobe with a dense tuft of fine, curved setae. S6+7 large (almost subequal to epandrium) and complex: S6 extending ventrally under (dorsal to) S5 and with dark, T-shaped posterior extension, the apex of which has a rippled margin; dorsal to this lies a tubular, basally constricted sclerite with heavily sclerotized, flattened, disc-like apex; S7 with elongate, dextral extension reaching across to ring sclerite; S8 with dorsal, anteromedial semicircular emargination; ring sclerite well-developed. Epandrium very large (only slightly smaller than head); cercus indistinct from epandrium; subepandrial sclerite thick, X-shaped. Hypandrium triangular, anteromedial apodeme curved upwards anteriorly. Surstylus short and complex: anterior half composed to two lobes: a semicircular dorsal lobe which is bent inwards anterodorsally and a thick, triangular, beak-like, ventrally setose ventral lobe; posterior half subtriangular, bulging laterally, with a broad anterior point, an elongate posterior ‘arm’, and a broad, rounded ventral lobe which has many long setae on the outer surface and a patch of thickened setae along the inner surface. Postgonite elongate, triangular and slightly bent forwards apically into a small hook. Phallapodeme elongate and curved; basiphallus large and saddle-shaped (often visible between surstyli in dried specimens). Distiphallus extremely large (~11% total body length), divided into basal and apical sections: basal section elongate, sclerotized and curved, with small lower knob articulating with apical section and spinose, membranous upper apex; apical section composed of a bent, trough-like, sinuate lower sclerite and a pair of flattened, curved lateral sclerites which fit along inner surface of lower sclerite. FEMALE ABDOMEN. Female unknown. Remarks Pleuroseta monteithi sp. nov. is externally almost indistinguishable from, and internally very similar to, P. ingens sp. nov. As such, the male genitalia are required to identify this species: S5 with a triangular posteromedial emargination, S6 with a flattened, T-shaped posterior extension, anterior lobe of surstylus with a more elongate triangular ventral lobe and a semicircular dorsal lobe, postgonite thicker and straighter along the anterior margin, and basal part of the distiphallus more evenly curved without an elongate apical extension. Both known specimens of Pleuroseta monteithi sp. nov. were collected some 150 km north of the northern-most collection locality of the similar P. ingens sp. nov. (from Mount Hypipamee National Park), suggesting that they might be allopatric or parapatric sister species.

How this classification was reachedexpand
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.
