Abstract

fetched live from OpenAlex

Abstract This chapter provides a checklist for the family Megastigmidae. It provides information on species diversity, host records, distribution records by province in Iran, as well as world distribution. Comparison of the megastigmid fauna of Iran with adjacent countries indicates that the faunas of Turkey (20 species) and Russia (17 species) are both more diverse than Iran (12 species), followed by Kazakhstan (six species), Armenia (five species), Turkmenistan (three species) and Afghanistan, Azerbaijan and Iraq (each with one species); no species have been recorded from Bahrain, Kuwait, Oman, Qatar, Pakistan or Saudi Arabia. Furthermore, 17 species were recorded from the former USSR. Turkey shares eight known species with Iran, followed by Russia (seven species), Armenia (four species), Turkmenistan (three species) and Afghanistan, Azerbaijan and Iraq (each with one species shared).

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.

Not 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.
