Abstract

fetched live from OpenAlex

Cyclocephala berti Delgado, 1992 Material Examined. Two males and five females labeled: “ MÉXICO: Veracruz, Zongolica, La Quinta, Amatitla. 29-30-V-2011. Luz mercurial. Bosque mesófilo de montaña. Alt. 1250 m, E. Mora, L. Delgado y L. Lara cols”. One female with same data, except 31-VI-2011. One male with same data, except 31-VII-2011. The specimens are deposited in the following collections: University of Nebraska State Museum (Nebraska, USA) 1 ♂ 1♀; Instituto de Ecología, A. C. (Xalapa, México) 2♀; L. Delgado Collection (Mexico City) 1 ♂ 1♀; and E. Mora-Aguilar Collection (Xalapa, México) 1 ♂ 2♀. This species was described based on only one male specimen from the H. & A. Howden collection (now in Canadian Museum of Nature, Ottawa, Canada). The specimen was collected in the Los Tuxtlas region on the southeastern slope of the Volcán de San Martín, Veracruz, Mexico. Recently, nine specimens were collected at the Sierra de Zongolica, Veracruz. Male specimens agree with the description of C. berti, except for their larger size (length 13.7–16.8 mm, width across the humeri 6.5–7.3 mm), head completely covered with long and erect setae, and each elytron with 3 or 4 diffuse spots. Female specimens collected are similar to males except in the dimorphic characters, and are different from other species of Cyclocephala. Description of the previously unknown female of C. berti is as follows: Total length 13.1–14.8 mm, width across the humeri 6.2–6.7 mm. Similar to male except in the following respects: Head and pronotum glabrous. Each elytron with 3–4 small, fuscous spots. Elytra and scutellum glabrous, except for the apex and posterior lateral third of elytra with small, sparse setae. Epipleuron expanded at level of metacoxa to abdominal sternites 2–3, with small, rounded, obtuse tooth between abdominal sternites 2–3. Pygidium almost flat, glabrous, except with small, erect setae on the base. Protibiae with basal tooth normal, teeth equidistant. Protarsus not enlarged, claws simple. Metatarsi slightly longer than metatibia.

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.

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.
