Paragrallomyia bifurcata Ferro & Marshall 2020, new species
Bibliographic record
Abstract
Paragrallomyia bifurcata new species (Figs. 10–11) Description (female only): Body length 6 mm; wing 4 mm. Head and abdomen black, thorax black. Palpus dark brown except for white outer face. Clypeus brown with sparse pale microsetulae. First flagellomere dark brown. Fronto-orbital plate dark brown. Row of katepisternal setae brownish. Fore tibia dark brown. Fore tarsus mostly white, tarsomere one brown on basal half only. Hind femur mostly brown, white on basal quarter and with a small angled preapical white ring. Tergites black. Oviscape black. Head: First flagellomere covered by pale microsetulae. Frontal vitta with a darkened spot anterior to ocellar plate. Frontal vitta flat, not swollen anterior to ocellar plate. Epicephala converging, not immediately merging posterior to ocellar plate. Epicephalon somewhat swollen above frontal vitta level. Epicephalon somewhat swollen above frontal vitta level. Thorax: Mesonotum with lines of thin brownish microsetulae. Anterior half of postpronotal lobe bare. Femur covered with sparse black microsetulae. Mid and hind tibia almost cylindrical, sulcus on outer face weak. Cervical sclerite with a whitish oval swelling. Cell r 4+5 open at the tip of the wing. Abdomen: Single spermathecal duct with an apical small rounded swelling. Single spermatheca cylindrical and forked, with sparse small rounded processes (Fig. 11). Paired spermathecal duct uniformly thick, slightly tapered on apical third before splitting into stems. Paired spermathecal duct stems uniformly thick, slightly convoluted. Paired spermathecae oval with an apical nipple-like swelling. Type material: Holotype: COSTA RICA. Heredia, Rara Avis Nat. Res. 12 km S Las Horquetas, 10º17’00” N 84º02’50” W, 700 m, 22–27.II.2005, S. A. Marshall (1 ♀, DEBU00241651, MNCR). Paratypes: Heredia, Rara Avis Nat. Res. 12 km S Las Horquetas, 10º17’00” N 84º02’50” W, 700 m, 22–27.II.2005, S. A. Marshall (3♀, DEBU00241632, DEBU00241634, DEBU00241650). Distribution: Costa Rica. Etymology: The specific name refers to the remarkable bifurcate single spermathecae of this species. Comments: The conspicuously bifurcate single spermathecae confirm that P. bifurcata is distinct from the very similar P. albibasis.
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.
