Head dark brown, lower fifth of frons orange; face, gena, and antenna orange-brown. Frontal width 2.2× frontal height. Two pairs of strong interfrontal bristles surmounting a fine third pair; anterior orbital 0.5× length of posterior. Palpus yellow. Eye very large, greatest height about 4.5× shortest genal height. Thorax brown, scutum with paler lateral edges. Two pairs of dorsocentral bristles (anterior pair distinct, 0.5 × length of posterior pair) separated by 6–7 rows of acrostichal setulae. Membrane around prosternum bare. Legs brown, femora darker. Fore femur with three large ventral preapical setae. Ventral surface of male mid tibia with two rows of stout setae in apical fifth. Wing (Fig. 8I) slightly infuscate. CS2 0.9× CS3. Halter brown. MALE ABDOMEN (Figs 116B–C, 117). Dark brown, posterior edges of tergites sometimes slightly desclerotized. T2–5 and S2–4 uniformly long-setose with large posterolateral setae. S5 rectangular, 1.1× length of S4, anteromedial half pale, posterior half long-setose with a dark, triangular posteromedial area. Anterior flange of S6+7 large, 1.0× as long as wide. Sclerite A forming a large, pale, densely setulose, elongate rectangular piece; sclerites B and C absent; sclerite D small, dark, ovoid, originating at apex of posteromedial dark area of S5; sclerite E dark, elongate with a narrow, curled, mesial end; sclerite F dark with an elongate, rectangular mesial end; sclerite G very large, bulbous, ring sclerite large and integrated into posterior surface of sclerite G. Epandrium small, 0.4× length of S8, height 1.2 × maximum length and 0.8× maximum width, long-setose; perianal pads weakly developed. Pseudocercus absent; halves of subepandrial sclerite flat and medially fused. Subcercus large, triangular in posterior view with a large, dorsoventrally flattened apical process. Hypandrium with sinuate, dorsoventrally flattened anteromedial apodeme. Surstylus subquadrate with two small anterior lobes and a larger, curved, long-setose, posteroventral lobe. Postgonite short, basal half broad with a slight anterior emargination, apical half constricted and curved anteriorly, apex with a thin, sinuate process. Phallapodeme large, apex dorsoventrally flattened; basiphallus large, basal part stout and connected to distiphallus by a neck-like distal part, posteriorly with a large (almost as long as postgonite), sinuate epiphallus; distiphallus unusual, basal half sclerotized and gently sinuate, apical half bent posteriorly, extending parallel to basal half, ventrally flattened with large membranous ventral folds. FEMALE ABDOMEN (Fig. 118). T7 broad, simple; T8 divided into a broad, membranous, dorsal sclerite and two large, dark, lateral sclerites, posterolateral corners slightly expanded and rounded. Epiproct large, subtriangular, medially split, anteromedially and posteriorly desclerotized, and setulose in posterior two-thirds. Cercus elongate, apically pointed with long apical, dorsal, lateral, and apicoventral setae. S7 very large, broadly desclerotized posteriorly with 4–5 large posterior setae; S8 divided into two small, dark, lateral sclerites. Hypoproct entirely setulose with short but thick ventromedial setae. Three spermathecae, bulb elongate, cylindrical but crumpled, finely striate with shallow invaginations at both ends (ducts connecting near middle), both with a stout, finger-like, central process. Distribution Neotropical: Ecuador. Remarks Sclerocoelus puyensis sp. nov. is superficially similar to S. punensis sp. nov. but can be distinguished by the medially flattened or even slightly convex male S5, apically tapered surstylus, apically flattened and posterodorsally projecting subcercus, and evenly curved postgonite. Sclerocoelus puyensis, like other ‘basal’ Sclerocoelus lineages, is a high Andean species. All known specimens are from over 3000 m a.s.l., mostly in relatively small pockets of moist decaying plant material such as fallen Puya (Bromeliaceae) stems, debris along high alpine streams, or prostrate Polylepis (Rosaceae) branches.
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.
How this classification was reachedexpand
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.
