Abstract

fetched live from OpenAlex

Atrichopogon (Meloehelea) ladislavi Tóthová, new species Diagnosis: Female adult: only extant species of Meloehelea in the Nearctic Region with a very long slender third palpal segment with PR> 4 and about 22 large mandibular teeth. Description: Female adult: Descriptive measurements in Table 1. Head: Antenna medium brown, with 13 flagellomeres, flagellomeres 1–8 disciform, proportions as shown in Fig. 3 B. Mandible well developed, with 20–22 teeth, 5–6 distal teeth very small, 9 at midlength broad. Laciniae with 12–13 teeth. Palpus (Fig. 3 C) with very long, slender third palpal segment, pit at midlength. Thorax: scutum, scutellum dark brown (Fig. 3 A). Wing (Fig. 3 E) without pattern of pigmented membrane, with many macrotrichia on the entire membrane. Halter: white. Legs: Light brown; empodia present. Abdomen (Fig. 3 D): light brown. Genitalia: 2 equal ovoid spermathecae, each with short neck. Male adult: unknown. Distribution and bionomics: The specimens of A. ladislavi were collected in a woodland habitat not far from a river near Rowanton, Québec, Canada (46°24’ N, 77°45’ W, 380 m). TAXONOMIC DISCUSSION: According to a key to the subgenus Meloehelea which includes New World species (Wirth, 1980), the characters of A. (M.) ladislavi indicate that it belongs in the lucorum group. This species is similiar to the European A. (Meloehelea) winnertzi Goetghebuer, 1922, which also has a distinctive very long and slender 3rd palpal segment (PR>4.3), however the difference in mandibular teeth is obvious. While A. (M.) winnertzi has mandibles with 31–36 fine teeth, A. (M.) ladislavi has 20–22 large mandibular teeth. Types: Holotype, female adult on microscope slide, labeled “ HOLOTYPE Atrichopogon ladislavi Tóthová, nr. Rowanton, P.Q., 29. vii. 1954, J.A. Downes, No. J.A.D. 126/4/29, CNC“; paratype: 1 female, from type locality, 29. vii. 1954, J.A. Downes, No. J.A.D. 126/4/28. SPECIMENS EXAMINED: Canada, Québec, Rowanton, 29. vii. 1954, J.A. Downes, 2 females No. J.A.D. 126/4/ 29, 126/4/28. Derivation of specific epithet: This species is named after the senior author´s beloved father who will stay in her loving memory.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
