Late Triassic immature Diptera (Insecta): aquatic and rheophilic
Bibliographic record
Abstract
Abstract Immatures of Diptera are extremely rare in the Triassic fossil record and up to now they are only known from the early Anisian of Europe (Upper Buntsandstein of France and Spain). Herein, three immatures are described from the Norian (Upper Keuper) of Seinstedt, Germany: larva of Tanyderidae Larvaderus triassicus gen. et sp. nov. and pupa of Simuliidae Simulipupa curriei gen. et sp. nov., and Ramobuccina herrigi gen. et sp. nov., a pupa whose affinity is uncertain. Branched respiratory organs of both pupae suggest a rheophilic mode of life. The expansion of the order to (fast-) flowing waters no later than the Late Triassic is proven by the Norian immatures, which were strictly aquatic and could live without contact to the water surface in contrast to Anisian ones. The immature Tanyderidae and Simuliidae are the oldest records of these extant families. Simulipupa gen. nov. is the oldest record of a putative dipteran bloodsucker.

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.
