Sphictostethus striatulus Roig-Alsina 1985
Bibliographic record
Abstract
Sphictostethus striatulus Roig-Alsina CHILE: Araucanía Region, Cautín Province, Pucón, Huerguehue National Park; 25 February 2021; G. Andrés. Host: Unidentified species (Anyphaenidae), adult or subadult female. The first photograph shows the wasp standing over the paralyzed ghost spider as it laid on the ground, ventral side upward, grasping its left forecoxa with her mandibles. The second photograph shows S. striatulus pulling the spider in the opposite direction of an S. xanthopus, grasping its right forepatella or forefemur with her mandibles, while S. xanthopus (Spinola) grasps the trochanter of the third left leg with her mandibles. The third photograph shows the two wasps grappling atop the spider while it laid, ventral side upward, on the ground with S. xanthopus attempting to sting S. striatulus and bite it with her mandibles. The S. striatulus is grasping the patella of the spider’s second right leg (Andrés 2021). CHILE: Santiago Metropolitan Region, 12 km W of Paine, Altos de Cantillana Reserve; 23 September 2012; B. Segura. Host:? Grammostola sp. (Theraphosidae), juvenile. The wasp dragged the paralyzed tarantula backwards on the ground, dorsal side upward, grasping the base of its right foreleg with her mandibles. An accompanying video of the same event shows the wasp searching for and finding the paralyzed tarantula as it laid on its left side on the ground, then grasping the base of its right foreleg with her mandibles and dragging it backwards on the ground (Fig. 13; Segura 2012; Segura, Santiago, Chile, 2021 pers. comm.).
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.
