Paragrallomyia brasiliensis Ferro & Marshall 2020, new species
Bibliographic record
Abstract
Paragrallomyia brasiliensis new species (Figs. 12–14) Description: Body length 7 mm; wing 5 mm. Head and abdomen dark brown, thorax black. Palpus dark brown except for white outer face. Clypeus brown with sparse pale microsetulae. First flagellomere dark brown. Fronto-orbital plate yellowish-brown. Row of katepisternal setae brownish. Fore tibia dark brown. Fore tarsus mostly white, tarsomere one brown on basal ¾ only. Hind femur mostly dark brown, white on basal fifth and with a small angled preapical white ring. Tergites dark brown. Oviscape dark brown, apex brownish. 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 (Fig. 12). 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 cylindrical, without sulcus on outer face. Female cervical sclerite brown and smooth, without swelling. Cell r 4+5 open at the tip of the wing. Abdomen: Female abdomen: Single spermathecal duct with an apical small swelling. Single spermatheca cylindrical. Paired spermathecal duct with a rounded swelling apically before splitting into stems. Paired spermathecal duct stems tapered on basal third, with a rounded swelling on apical half. Paired spermathecae oval and striate, invaginated apically only (Fig. 13). Male abdomen: Inner basal lobes of the copulatory fork arms absent. Ejaculatory apodeme bigger than epandrium and with a broad blade, bigger than sperm pump. Type material: Holotype: BRAZIL. Amazonas, Rio Negro, downstream Uaupes, last right tributary of Rio Curicunari, 5.III.1994, M. von Tschirnhaus coll. (1 ♀, DEBU00280365, INPA). Paratype: BRAZIL. Amazonas, Rio Jaú, 015234S 613515W, 29.VII–08.VIII.2001, Arm. suspensa, lâmina d’água, Henriques & Vidal colls. (1 ♂, DEBU0001088959). Distribution: Brazil Comments: This Brazilian species is distinct for its light brown fronto-orbital plate and the absence of the inner basal lobes on the copulatory fork. The long and cylindrical paired spermathecae are also unusual. The genitalia of the holotype, the only available male of this species, was partially destroyed.
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.
