Bibliographic record
Abstract
Pseudoholostrophus (Pseudoholostrophus) impressicollis (LeConte, 1874) (Figs 1, 8, 17, 26) Eustrophus impressicollis LeConte, 1874: 69; Horn, 1888: 36; Leng, 1920: 238; Csiki, 1924: 10; Poole and Gentili, 1996: 299; LeSage, 1991: 246; Hatch, 1965: 67, Plate IX, fig. 1; Nikitsky, 1998: 47, Plate 7 figs 9-11; Young and Pollock, 2002: 416. Lectotype, sex unknown, labelled “Vanc. / Type 4781 / Eu. impressicollis Lec. ”, in MCZ. Diagnosis This distinctive species can be separated from all Nearctic species of Eustrophinae by the combination of the following characteristics: uniform red-brown color, short, inconspicuous dorsal pubescence, widely separated eyes, and smooth meso- and metatibiae. Description TL 6.0- 6.2 mm; GEW 2.1-2.7 mm. Body (Fig. 1) elongate oval, moderately parallel sided. Dorsal and ventral color uniformly dark rufous, including antennae and legs; dorsal pubescence very short, inconspicuous (Fig. 1); eyes (Fig. 8) widely separated (> 3 x length of first antennomere), inner margin of eye slightly emarginate; antennae (Fig. 17) relatively short, antennomeres 7-10 distinctly widened; antennomere 7 triangular, 8-10 wider than long; antennal sensilla completely annular (as in Fig. 25); last maxillary palpomere distinctly widened, securiform; prosternal process elongate, spatulate distally extended past posterior margin of procoxae, bent dorsally at distal end; prothoracic episternal suture absent; elytral punctation fine, punctures not arranged in longitudinal striae; meso- and metatibiae with scattered short spines, without oblique ridges (as in Fig. 15). Distribution (Fig. 26) Th is species is restricted to extreme western North America. In Canada, all known records are from Vancouver Island and the adjacent mainland of British Columbia, north to the Queen Charlotte Islands. Th is is seemingly one of the rarest, or most infrequently collected, species of Nearctic Eustrophinae; most localities are represented by a single specimen. US distribution: WA (Hatch 1965), OR, CA. Natural history Little is known regarding the habits of P. impressicollis. Label data indicate the following: under bark of pine; in rotten log; fungus. Material examined Specimens were examined from the following Canadian localities: BRITISH COLUMBIA: Gabriola, 2.VI.1994, BF & JL Carr, lot 7, (CARR, 1); Qualicum, 16.IX.1962, BF & JL Carr, lot 1, (CARR, 1); Vancouver Island, Kye Bay, nr. Comox, 5 m, 2.VII.1980, H. & A. Howden, (CMNC, 1); Queen Charlotte Islands, Laskeek Bay, Haswell Island, 2-22.VI.2000, 52°51’42”N, 131°41’06”W, Allombert, Sylvain, (RBCM, 1).

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.
