Revision of Neotropical aphrophorine spittlebugs, part 1: Ptyelini (Hemiptera, Cercopoidea)
Bibliographic record
Abstract
Cephisus Stål, formerly with only 3 recognized species, is now known from at least 10 species ranging from southwestern USA to Argentina. Eight are keyed and described, including C. siccifolia (Walker), the economic species in South America, C. variolosus (Walker), the common species in Central America, C. brevipennis sp. nov. and C. laticeps sp. nov. from Mexico, plus C. magnificus sp. nov. from Brazil; two other biological species were identified in the C. variolosus species complex from the results of genetic “barcoding.” These are differentiated from Plinthacrus phaleratus, P. mexicanus and P. irroratus (all described by Spinola in 1850) that are new synonyms of Novaphrophara tasmaniae Lallemand, 1940 (as N. phalerata comb. nov.), a species collected recently only in Madagascar. These two genera along with 6 others are placed in the redefined tribe Ptyelini (= Takagiinae syn. nov.) as sister-genus to the palaearctic genus Cnemidanomia Kusnezov (=Takagia Matsumura), suggesting a pre-Oligocene dispersal from the old world to the new. A preliminary key is provided to the families and tribes of Cercopoidea represented in the new world.
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.
