Abstract

fetched live from OpenAlex

Allocapnia pygmaea (Burmeister) (Figs. 67-72) Semblis pygmaea Burmeister 1839:874. Lectotype ♂ (Zoological Museum Berlin), Pennsylvania [no specific site], designation by Needham & Claassen, 1925:278. Capnella pygmaea: Needham & Claassen, 1925:277. Allocapnia torontoensis Ricker 1935:257. Holotype ♂ (Canadian National Collection), Credit River, Cooksville, Peel Co., Ontario, synonymy proposed by Frison, 1942:265. Allocapnia pygmaea: Ross & Ricker, 1971:45. Material examined. Kentucky: Leslie Co., Middle Fork Kentucky River, Daniel Boone Parkway, 8 February 1998, B. C. Kondratieff, R. F. Kirchner, 30♂, 8♀ (CSUC). Powell Co., Middle Fork Red River, Hwy N, 10 February 1998, B.C. Kondratieff, R.F. Kirchner, 21♂, 6♀ (CSUC). New York: Tompkins Co., Salmon Creek, Myers, 26 February 2000, M.H. Alford, 23♂, 12♀ (BPS). Tompkins Co., Ithaca, Cascadilla Creek, Cornell University, 26 February 2000, M.H. Alford, 8♂, 3♀ (BPS). Tompkins Co., Owasco Inlet, Stevens Rd, near Groton, 26 February 2000, M.H. Alford, 6♂, 2♀ (BPS). West Virginia: Mason Co., Ohio River, Apple Grove, 3 March 2001, B.C. Kondratieff, R.F. Kirchner, R.E. Zuellig, 5♂, 4♀ (CSUC). Male epiproct. Apical segment of upper limb ca. 340- 400 μm long, armed on apical ca. 176-220 μm with dense patch of wave-like spikes (Figs. 67-69); apical segment ca. 125-135 μm wide at base, tapered to a narrow, rounded tip. Basal segment of upper limb ca. 303-309 μm long and ca. 79-103 μm wide at midlength; basal segment with median groove narrowed toward base of apical segment (Fig. 67). Greatest width of lower limb ca. 148-194 μm; lower limb bearing a sparse, marginal row of long setae in apical third (Fig. 69). Male tergal process. Prominent raised structure on abdominal tergum 8 (Figs. 70-72). Bilobed process on tergum 8 ca. 162-174 μm wide and bearing a deep Ushaped mesal notch; notch width ca. 44-56 μm. Lobes of process diverge in dorsal aspect, but appear straight and slightly swollen in lateral aspect; lobes covered with scale-like structures; anterior face bearing a shallow, transverse groove.

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.
