Comprehensive taxonomic, faunistic, biological, and geographic inventory and analysis of the Sciomyzidae (Diptera: Acalyptratae) of the Delmarva region and nearby states in eastern North America
Bibliographic record
Abstract
Genera and species of Sciomyzidae known from the Delmarva region (Delaware, the District of Columbia, Maryland, Virginia, and West Virginia) and nearby states are reviewed taxonomically, faunistically, biologically, and geographically. Although restricted to the taxa in that area, this work amounts to a revision of the sciomyzid fauna of that portion of the Nearctic region. Treated are 91 species in 19 genera, i.e. 46% of the 199 species and all but four of the 23 genera of Sciomyzidae known from the Nearctic Region. Included are 67 species in 16 genera from Delmarva and 24 other species in 10 genera from nearby states. Euthycera flavescens (Loew) is resurrected; Renocera cressoni Mathis and Knutson sp. nov. is described from eastern North America; R. amanda Cresson is given new status as a junior synonym of R. longipes (Loew); and Chaetomacera brevis Cresson, R. cyathiformis Melander, R. pacifica Curran, and R. bergi Steyskal are given new status as junior synonyms of R. striata (Meigen). Newly diagnosed are taxonomic categories ranging from family to species level, including the first diagnoses of abdomens of females of many species, where known. Provided for each genus and species are annotated taxonomic/nomenclatorial catalogs of all North American references to all species, with generic combinations noted, with previously unrecorded synonymies as well as North American literature references, illustrations, and information on natural history and morphology of immature stages. Results of cross-mating studies of Dictya are reported and discussed. Provided are label data from examined specimens, lists of Canadian provinces and U.S. states from which reviewed species have been recorded, and detailed maps of geographical distribution of species in Delmarva, with references to previously published maps.
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.
