The New World genera of Parathalassiinae (Diptera: Empidoidea: Dolichopodidae s.l.), with new species of <i>Thalassophorus</i> and <i>Eothalassius</i>
Bibliographic record
Abstract
Abstract The parathalassine genera Thalassophorus Saigusa, Eothalassius Shamshev and Grootaert, and Chimerothalassius Shamshev and Grootaert are recorded from the New World for the first time. Thalassophorus arnaudi Brooks and Cumming sp. nov. is described from specimens collected at coastal localities in British Columbia, Oregon, and California, and represents the second known species in the genus, the type species being T. spinipennis Saigusa, known only from Rishiri Island in Hokkaido Prefecture, Japan. Detailed illustrations of the male genitalia of T. spinipennis are provided. Eothalassius borkenti Cumming and Brooks sp. nov. is described from specimens collected along the Pacific coast of Costa Rica, bringing the total number of described species of this former Southeast Asian genus to three, with one probable additional described species in the Mediterranean region. The genus Chimerothalassius , which was previously known from a single New Zealand species, is recorded from the island of Dominica, based on a female specimen plus a slide-mounted wing of an undescribed species. A new undescribed parathalassiine genus is also recorded from Chile, based on limited material of two undescribed species. A key to the six genera of Parathalassiinae in the New World, including Parathalassius Mik and Microphorella Becker, is given, as are some preliminary remarks on the limits and phylogenetic relationships of the parathalassiine genera.

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.
