Abstract

fetched live from OpenAlex

Paragrallomyia quaternaria new species (Figs. 43–46) Description: Body length 6 mm; wing 5 mm. Head and abdomen dark brown, thorax black. Palpus dark brown except for white outer face. Clypeus dark brown with sparse pale microsetulae. First flagellomere dark brown. Frontoorbital plate dark brown. Row of katepisternal setae brownish. Fore tibia brown. Fore tarsus white with brownish pubescence ventrally at base of tarsomere one. Hind femur mostly dark brown, white on basal fifth and with a small angled preapical white ring. Tergites dark brown. Oviscape dark brown. 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. 43). 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 brown and with a rounded swelling. Cell r 4+5 open at the tip of the wing. Female abdomen: Four spermathecae (Fig. 44). One pair oval and smooth, connected by short and broad stems, spermathecal duct broad apically only. Other pair cylindrical and elongated, connected to a uniformly thick duct with two small rounded swellings apically. Male abdomen: Inner basal lobes of the copulatory fork arms absent. Ejaculatory apodeme smaller than epandrium and with a diminute blade, length subequal to sperm pump. Phallapodeme short, not extending to anterior limit of hypandrium. Distiphallus long, longer than epandrium; phallic bulb subequal in length and width. Distal distiphallus long and thin, almost 2x the basal distiphallus (Fig. 46). Type material: Holotype: BOLIVIA. La Paz, Heath River Wildlife Centre, ~ 21km SSW Puerto Heath, 12º40’S 68º42’W, 29.IV–12. V.2007, J. H. Kits (1♀, DEBU00282418, CBFC). Paratypes: BRAZIL. Amazonas, Rio Negro, Lago do Miratuca, 20.VII.1993, armadilha Shannon, L. S. Aquino (1 ♂, DEBU01086324, INPA); Pará, Tucurui, R. Tocantins, prox. cid. Muru. 26.III.1981 (1 ♀, DEBU). Distribution: Bolivia, Brazil. Etymology: The specific name (Latin quaternarius: consisting of four) refers to the four spermathecae of this species. Comments: P. quaternaria can be distinguished from other species in the complex by the presence of four spermathecae and the long and thin distal distiphallus (twice as long as basal distiphallus).

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.
