<p><strong>The old-world Zygonini tr. nov. (Hemiptera, Cercopoidea, Clastopteridae), with new taxa from the related Machaerotinae</strong></p>
Bibliographic record
Abstract
Three new species of old-world Clastopteridae belonging to Machaerotinae are described, two in new monobasic genera: Allox transfigurata (Hindolini) from Borneo and Irridiculum deformatum (Machaerotini) from Sulawesi. One new species Machaeropsis dramatica (Hindolini) is described from Borneo. It is the first male known from the genus and shows that Machaeropsis Melichar is not synonymous with Metaenderleinia Lallemand. Five other new species are described, belonging to a new, related tribe Zygonini. Two of these new species (Ambonga lanceolata and Pseudomachaerota cucullata) belong to formerly monobasic genera from Madagascar incorrectly assigned to Cercopidae and Aphrophoridae respectively. These are related to 3 new genera: (1) from Madagascar, Pseudoclastoptera with new species P. irrubesco and P. invidia; from sub-Saharan Africa, (2) Zygon with 1 new species Z. desegregatum, and (3) Hemizygon, the latter with 2 new combinations from Pseudomachaerota: H. grande (Maa) and H. saturnus (Linnavuori). Zygon is possibly the most basal genus in Clastopteridae, according to its remarkable antennal characters with 5 different types of sensilla that show how basiconic and coeloconic sensilla are homodynamous. Genera related to Zygon are widely divergent from other spittlebugs as measured by mDNA "barcode" data from the COI gene.
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.
