Abstract

fetched live from OpenAlex

A new species of the alpheid shrimp genus Potamalpheops Powell, 1979, is described on the basis of a single male specimen collected in a brackish water stream, 6 km from the sea, in southern Sri Lanka. Potamalpheops galle, new species, differs from all other species of the genus by a combination of several features, and appears to be closest to the South-East Asian species P. amnicus Yeo & Ng, 1997, P. miyai Yeo & Ng, 1997 and P. palawanensis Cai & Anker, 2004. The new species is the first record of Potamalpheops in South Asia and constitutes an important link between two major radiation zones of this genus, West Africa and South-East Asia/Australia.

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.
