Descriptions of larvae of the North American endemic stygobiontic Ereboporus naturaconservatus Miller, Gibson & Alarie and Haideoporus texanus Young & Longley (Coleoptera: Dytiscidae)
Bibliographic record
Abstract
The larvae of the North American stygobiontic dytiscid species Ereboporus naturaconservatus Miller, Gibson & Alarie, 2009 and Haideoporus texanus Young & Longley, 1976 are described with an emphasis on chaetotaxy of the head capsule, head appendages, legs, last abdominal segment and urogomphi. Both of these species share the presence of a nasale and the absence of the primary pores MXd and LAc, which have been recognized as synapomorphies for members of the subfamily Hydroporinae. Out of the common convergent characteristics associated with hypogaeic living, no synapomorphies were found that could relate Haideoporus texanus and Ereboporus naturaconservatus , which reinforces the hypothesis that these species evolved independently within the subfamily Hydroporinae. In terms of morphological adaptations, E. naturaconservatus stands as a remarkable hydroporine in that its larvae evolved a truncated last abdominal segment and a very elongate urogomphomere 1 relative to urogomphomere 2.

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.
