Megamelanus bicolor Ball (Hemiptera: Fulgoroidea: Delphacidae): a Specialist Planthopper on Saltgrass (Distichlis spicata; Poaceae) in Nebraska's Alkaline and Saline Wetlands
Bibliographic record
Abstract
Originally described in 1902, Megamelanus bicolor Ball is an infrequently collected delphacid planthopper whose host plants have remained unknown. Nymphs and adults were collected on saltgrass, Distichlis spicata (L.) Greene (Poaceae), in the critically imperiled saline wetlands of eastern Nebraska, as well as in alkaline wetlands of western Nebraska. We suggest that the planthopper is a saltgrass specialist. In addition to the new state record of Nebraska, we give other new North American records based on examination of museum specimens: Louisiana, Oregon, South Dakota, Texas, and Wyoming in the United States, and British Columbia in Canada. A diagnosis of M. bicolor and illustrations and photographs of the male terminalia are provided.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
