A review of the Callogobius (Teleostei: Gobiidae) from the Red Sea with the description of a new species
Bibliographic record
Abstract
Five species of Callogobius Bleeker have been previously reported from the Red Sea: C. amikami Goren, Miroz & Baranes, C. clarki (Goren), C. dori Goren, C. flavobrunneus (Smith), and C. maculipinnis (Fowler). Records of C. bifasciatus (Smith) in the Red Sea are referable to C. clarki. Callogobius amikami has been previously known only from a single specimen, the holotype from the Red Sea, and two photographs, a live juvenile from Oman and a live specimen at an aquarium at Coral World, Eilat. We obtained a possible additional juvenile from the Red Sea, although we are unable to definitively determine its identity. Red Sea specimens previously identified as C. maculipinnis [or C. irrasus (Smith)] represent a new species, distinguished from the latter by normally having four sets of transverse mandibular rows on each side (rather than three); this species is described here as Callogobius pilosimentum sp. nov. Four specimens of an additional, undescribed species of Callogobius, C. sp. A, have been collected from the Red Sea, but we withhold a formal description because this species is currently under study by colleagues. Callogobius sclateri (Steindachner), previously known from the Indo-West Pacific, is reported from the Red Sea for the first time. A key to all seven species is provided. Each species is photographed, habitat is described and a brief description with detailed comparisons is provided. The new species and C. clarki are endemic to the Red Sea.
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.
