FIVE GENERA OF NEW-WORLD “SHOVEL-HEADED” AND “SPOON-BILL” LEAFHOPPERS (HEMIPTERA: CICADELLIDAE: DORYCEPHALINI AND HECALINI)
Bibliographic record
Abstract
Abstract New-world leafhoppers with strongly flattened heads are here assigned to three tribes: Deltocephalini (six genera), Dorycephalini (two genera), and Hecalini (seven genera). Revised keys are presented to the new-world genera, and 44 new-world species of the Nearctic genera Attenuipyga Oman (Dorycephalini) and Neohecalus Linnavuori, the Holarctic genera Hecalus Stål and Memnonia Ball, and the widespread new-world genus Spangbergiella Signoret (Hecalini). In Dorycephalini, Attenuipyga (with subgenus Dorycara Emeljanov, stat.nov .) has nine species, including Attenuipyga (s.s.) joyceae sp.nov . from Manitoba and Dorycephalus sinuatus Beamer, 1942 b = Dorycephalus minor Osborn, 1920, syn.nov . In Hecalini, 10 species in Hecalus , 3 in Neohecalus , and 15 in Memnonia are recognized, including 20 species formerly in Parabolocratus Fieber, plus Hecalus finnamorei sp.nov ., Neohecalus magnificus sp.nov ., Memnonia anthalopus sp.nov ., Memnonia maia sp.nov ., and Memnonia panzeri sp.nov . from the northern prairies and Memnonia leptalea sp.nov . from the Gulf states. Parabolocratus continuus DeLong, 1938 and Parabolocratus planus Shaw, 1932 are reduced to subspecific status in Hecalus montanus , and three names are synonymized: Parabolocratus inflatus DeLong, 1938 = Hecalus montanus (Ball, 1900); Parabolocratus rotundus DeLong, 1938 = Hecalus major (Osborn, 1915); and Parabolocratus elongatus DeLong, 1938 = Memnonia grandis (Shaw, 1932) syn.nov .

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; a candidate call from one teacher head, not a consensus.
