Type material. Holotype MCZ 243 (Scudder’s no. 7982). A poorly-preserved articulate specimen in probably dorso-lateral aspect. Verbatim label data [typed]: (1) “Mus. Comparative Zoölogy, Cambridge / No. 243/ Tribochrysa inaequalis / Scud / Florissant Miocene”; (2) [handwritten]: “ 243 type Tribochrysa inaequalis Scud / Florissant / Neuroptera: Chrysopidae ”. The specimen has red and black ink writing on the rock that says “7982 / 243”, and a red paper label glued to the rock that says “Type.”. The specimen is covered with Canada balsam. Type locality and horizon. USA: Colorado: Teller County: Florissant (precise collecting locality unknown); Eocene, late Priabonian; Florissant Formation. Diagnosis. May be distinguished from T. firmata by more closely spaced subcostal veinlets (seven between origin of RP and third ra-rp) [T. firmata: five– six]; 10 branches of RP [T. firmata: eight]. Redescription. Body very poorly preserved, with only one eye well discernible (ca. 0.5 mm in diameter). Forewing ca. 12.5 mm long, ca. 4.7 wide (length to width ratio 2.66). Costal space relatively narrow. Preserved subcostal veinlets simple, widely spaced. Pterostigma, distal part of Sc, RA not discernible. RA with nine preserved crossveins (apparently ten complete). Origin of RP relatively far from wing base (at ca. 0.22 complete length). Anterior trace of RP zigzagged, with ten branches. Basal crossvein between RP, M (1r-m) rather long, connecting anterior trace of RP, MA within im at nearly proximal one-fourth length. M arched proximad fork; dividing to MA, MP distad level of origin of RP. MA, MP strongly curved; MA rather shallowly forked distad Psc; MP deeply forked at Psc. Crossvein between MA, MP (1im) rather long. Im elongate, almost not divergent distally (length/width 4.2). Psm poorly developed, strongly zigzagged. Crossvein 2m-cu very long, connecting im, CuA at nearly proximal one-ninths im length. CuA probably with three simple branches. Psc rather well developed, slightly zigzagged. CuP deeply forked. Crossvein 2icu connecting CuA, anterior branch of CuP proximad 2m-cu. CuA, A1 closely approaching for short distance. A1, A2 simple. Two gradate series of crossveins: inner series arranged in strongly broken line, with eight preserved crossveins distad MA (apparently 8–9 complete); outer series arranged in slightly curved line, with seven crossveins distad RP2 (apparently eight complete). Hind wing very poorly preserved. Remarks. Much of the fossil is obscured by a covering of Canada balsam, and so we are only able to describe the forewing venation.

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.
