Head with 4 interfrontal setae and row of 6–7 small setulae on inner margin of orbital plate. Gena with 2 strong setae and 6–8 smaller setulae. Acrostichal setulae in 6–8 rows. Costagial seta extending slightly beyond humeral break. Second costal sector ~1.2 × as long as third. Length of M 1 between crossveins dm-cu and r-m 2.0× dm-cu; CuA 1 stub vein ~4.0× M 1 stub vein. Male mid femur with 20–21 strong setae in ventrobasal cluster. Male mid tibia with ventral comb of 8 robust setae on apical ½. MALE ABDOMEN (Fig. 14). Sternite 5 posterior margin with two distinct teeth on each side of large emargination; emargination forming a broad circular desclerotized area, ~⅓ width of sclerite and extending anteriorly ~¾ of length; margin of emargination with numerous setae on posterior ⅔. Transverse part of sternite 6 arcuate. Epandrium with pair of long mediolateral setae, with 2–3 smaller pairs lateral to large pair; subanal plate narrowly continuous below anal opening. Surstylus (in lateral view) with anterior lobe reduced to small basal swelling; posterior lobe elongate, length ~4.0 × basal width, tapering to narrowly rounded apex; bent posteriorly near basal ¼, with 4–5 setae on both ventral and dorsal surfaces. Cerci quadrate, weakly differentiated from each other and from epandrium, with pair of ventromedial setae. Postgonite narrow, slightly sinuate, with 4 small dorsal setulae on apical ½. Dorsal sclerite of distiphallus (Fig. 14 D–F) without swellings and not extending beyond apex of acrophallus. FEMALE ABDOMEN (Fig. 15). Posterior margin of tergite 7 entire. Medial part of tergite 8 short and kidneyshaped, with posterior margin emarginate. Epiproct triangular, elongate, with mid-line desclerotized. Cercus half as long as epiproct, with flattened apical seta; narrowly fused anterolaterally to epiproct. Posterior margin of sternite 7 entire or slightly arcuate. Spermathecae inverted cup-shaped (with duct, appearing mushroom-shaped) and wrinkled; sclerotized portion of ducts ~2.0 × length of spermatheca; common duct of paired spermathecae poorly sclerotized. Remarks This species is distinguished from other Rudolfina by characters of the surstylus and male sternite 5. The female epiproct is intermediate in shape between the strongly modified epiproct found in the R. exuberata group and the unmodified epiproct of other Rudolfina.
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.

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.
