Abstract

fetched live from OpenAlex

Halictophagus forthoodiensis Kathirithamby & Taylor, new species Type. Holotype ♂: USA, Texas, Coryell County, Fort Hood, UTM zone 14 R (NAD 1983) 607873mE 3451198mN, malaise trap (30.9.04 10am– 1.10.04 2pm. J. Kathirithamby, S. J. Taylor, C. E. Pekins (deposited in Oxford Museum of Natural History, Oxford). Locality Description: Vegetation at the site was savannah grassland (Fig. 1) dominated by King Ranch bluestem (Bothriochloa ischaemum), side­oats grama (Bouteloua curtipendula), Texas winter grass (Nassella leucotrica), and silver bluestem (Bothriochloa laguroides) with scattered plateau live oak (Quercus fusiformis) mottes; drainage from a sediment control pond outlet, just upslope of the malaise trap, was dominated by sedge (Carex spp.) and short ragweed (Ambrosia artemisiifolia). Description. Male. Total length, 1.12mm. Head width, 0.36mm, head length, 0.06mm. Antennae 7­segmented with 5 flagellomeres on segments 3–7. Scape and 2nd segment of equal length (0.03mm), flagellomeres on segments 3–5 (3rd & 4th = 0.21mm, 5th = 0.19mm, 6th & 7th = 0.13mm) (Fig. 2 a). Mandibles short (0.05mm) not meeting medially. Basal segment of maxilla one third length of palpi (base = 0.03mm, palpi = 0.09mm) (Fig 2 b). Prenotum length, 0.05mm; scutellum narrower (0.10mm) than postlumbium (0.13mm); postnoum long (0.55mm) and longer than rest of mesothorax (Fig 2 c). Wing length, 0.89mm. R2 half the length of R3; R5; MA and CuA touching wing margin (Fig 2 d). a. antennae; b. mandible (left) maxilla (right); c. thorax (dorsal view); d. wing; e. foreleg with pseudoplatella on tibia; f. tarsus on mid leg; g. tarsus on hind leg; h. lateral view of VIII, IX and X abdominal segments. Scale 1a, b, e­h = 0.2mm; c, d = 0.3mm. ae=aedeagus; a3=antennal segment III; cx=coxa; md=mandible; mn= mentum; mx=maxilla; pc=parascutum; ps=pseudopatella; psl=postlumbium; psn=postnotum; sc=scutum; sct=scutellum; st=sternite; t=tergite; ti=tibia; tf= trochanterofemur; ts=tarsus; vi­x=6th ­10th abdominal segments. Wing veination follows standard notation. Legs: Fore coxa as long as femur (0.12mm), tibia (0.0.8mm) with pseudoplatella (Fig. 2 e), 1st tarsomere large and round (Fig 2 f); mid femur slightly longer (0.15mm) than tibia (0.13mm); hind femur and tibia of equal length (0.15mm) (Fig. 2 g). Fine hairs on tibia and tarsus. Projection on VIIIth abdominal sternite large (0.11mm) (Fig 2 h). Abdominal segment IX long (0.15mm), and Xth nearly as long (0.12mm). Aedeagus, as most other strepsipterans, crescent shaped with pointed apex. Female: unknown. Host: unknown. Diagnosis. The pseudopatella on the fore­tibia is present only in three species of Halictophagus described so far: H. forthoodiensis sp. n., H. mackayi Bohart (1937) from Canada and H. languedoci Abdul­Nour (1969) from France. H. forthoodiensis differs from H. mackayi and H. languedoci by the shape of the anterior margin of the head which on dorsal aspect is straight and not v­shaped; mandibles very short, not meeting medially; maxilla with a very short basal segment and long palpi (curved upwards); antennal flabella on segments 3 and 4 distinctly longer 6 and 7, 5 intermediate in length; postlumbium large and two thirds longer than width (at widest point); 1st tarsomere on foreleg rounded; VIII abdominal sternite with a ventral projection, and Xth and IXth segments both extend equidistant. Etymology. This species is named for the type locality, Fort Hood, Texas.

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.
