Abstract
Monoctonus genriki Davidian, sp. nov. http://zoobank.org/ 012E1722-0D0F-4100-9C98-CD83BDE8C125 Fig. 1 Type material. Holotype: female, China, Sichuan Province, Jiuzhaigоu County, N Dajisi Village, 33 23ʹ32ʺ N, 103 48ʹ11ʺ E, h = 4205 m, 23.VI.2012 (I. Belousov, G. Davidian) (ZISP). Paratype: 1 male, with same data as holotype (ZISP). Description. Female. Body length 3.3 mm; length of antenna 2.6 mm; length of fore wing 2.9 mm. Head smooth, shining, with sparse setae, wider than mesosoma at level of tegulae. Eyes large, widely oval, with sparse short setae, below converging to clypeus. Face with long dense setae, its width 1.4 × height in middle. Malar space about 0.3 × height of eye. Eye in dorsal view 1.3 × longer than temple. Clypeus trapezoidal, with ten long setae, width of clypeus 1.4 × its medial height. Tentorial index = 0.16. POL 2.0 × Od. Maxillary palp with 4 segments, labial palp with 3 segments. Antenna filiform, with 18 antennomeres, covered by semi-erect setae, these setae about as long as width of basal flagellomeres. F1 and F2 almost same length, their length about 4.0 × width in middle. F1 without rhinaria (multiparous plate sensilla), F2 with two rhinaria (if studied from one side). Mesosoma. Mesoscutum with distinct notauli only in anterior one third. Propodeum with closed medial areola and additional short carinae around spiracles. Wings. Fore wing with closed central cell. Pterostigma about 7.5 × longer than its maximum width and 3.0 × longer than metacarp (1-R1). First abscissa of radial vein (r) 0.8 × as long as metacarp (1-R1), second abscissa (3- SR) about as long as metacarp (1-R1). First radiomedial vein (2-SR) almost absent near recurrent vein (m-cu). Metasoma. Petiole rugose, with distinct spiracular tubercles, length of petiole 2.0 × its width at level of spiracles. Ovipositor sheath plow-shape, narrowly subtriangular basally, widely obtuse apically. Length of sheath 3.5 × its maximum width and 5.6 × its apical width. Colour. Vertex dark brown, frons brownish, face light brown, mouthparts yellowish, apex of mandible infuscate. Antenna dark brown. Sternites, propleuron and legs yellowish brown. Meso- and metathorax, propodeum, petiole, remaining metasoma and ovipositor sheath brown. Male. Body length 1.7 mm; length of antenna 1.9 mm; length of fore wing 2.1 mm. Head smooth, shiny, with sparse setae, wider than mesosoma at level of tegulae. Eye large, wide oval, with sparse short setae. Maxillary palp with 4 segments, labial palp with 3 segments. Antenna with 19 antennomeres, with long semi-erect setae, length of setae almost equal to medial width of antennomeres. F1 and F2 subequal in length. F1 2.5 × and F2 2.2 × longer than its width in middle. Mesoscutum with distinct notauli in anterior one third. Propodeum with closed central areola. Fore wing. Pterostigma 6.2 × longer than its medial width, 3.3 × longer than metacarp (1-R1). First abscissa (r) of radial vein equal to its second abscissa (3-SR) and almost equal to metacarp (1-R1). Petiole rugose, with distinctly protruding spiracular tubercles, its length 2.5 × width at level of spiracles. Body monochromatic dark brown. Hosts. Unknown. Bionomics. Specimens were collected by shaking the bush Dasiphora fruticosa (L.) O. Schwarz (Rosaceae). Etymology. This new species is named in honour of Dr Genrik E. Davidian, one of the collectors of the type specimens. Comparative diagnosis. According to number of antennomeres, the new species is similar to M. montenegrinus Petrović & Tomanović, 2023 (Tomanović et al. 2023), parasitoid of the aphid Amphorophora sp. on Rubus sp., as well as to the Canadian M. parvipalpus Čkrkić, Petrović & Tomanović, 2019 (Čkrkić et al. 2019). Monoctonus genriki sp. nov. differs from M. montenegrinus by short petiole and wide ovipositor sheath (in M. montenegrinus, petiole 2.6 × longer than its width at level of spiracles, and ovipositor sheath 4.0 × longer than its maximum width). The new species also differs from M. рarvipalpus by number of segments in labial palps and presence of notauli in the anterior one third of mesoscutum (in M. рarvipalpus labial palps with 1 segment and notauli completely absent). From collected in the same time and locality Monoctonus sichuanicus sp. nov. the new species differs in having antenna with 18 antennomeres, propodeum with closed central areola, petiole of metasoma short and its length 2.0 × width at level of spiracles, and ovipositor sheath 3.5 × its maximum width. In М. sichuanicus sp. nov. antenna has 16 antennomeres, propodeum without closed areola and with only two anteriorly divergent carinae, petiole of metasoma long, with its length 2.5 × width at level of spiracles, and ovipositor sheath 2.5 × its maximum width.

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.
