Systematic revision of the Oriental planthopper genus Miasa Distant (Hemiptera: Fulgoromorpha: Dictyopharidae), with description of a new genus from southern India
Bibliographic record
Abstract
The dictyopharid planthopper genus Miasa Distant, 1906 (Orthopagini) is revised to include three known species, M. producta (Lethierry, 1888), M. smaragdilinea (Walker, 1857), and M. wallacei Muir, 1923, and two new species M. borneensis sp.n. and M. nigromaculata sp.n., all distributed in Southeast Asia. The confusion regarding the taxonomy of Miasa species is clarified on the basis of a critical review and examination of historical material. Male genitalia of all species and fifth-instar nymph of M. smaragdilinea are described and illustrated for the first time. A new genus Indomiasa gen.n. which is closely related to Miasa, is also established for a single new species, I. distanti sp.n., from southern India. A phylogenetic analysis based on morphological characters of adults was conducted to reconstruct the species-level phylogenetic relationships of Miasa and Indomiasa. The results show that the monophyly of Miasa and Miasa + Indomiasa is well supported. Keys to the genera of Orthopagini in the Oriental region and to the species of Miasa are provided.

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.
