Euconnus (Tetramelus) Motschulsky
Bibliographic record
Abstract
Subgenus Tetramelus Motschulsky Tetramelus Motschulsky, 1869: 257. Type species: Scydmaenus oblongus Sturm, 1838 (des. by Franz in Newton & Franz (1998): 147). Remarks. Morphological structures were illustrated and an emended diagnosis was given in Jałoszyński (2015c); further notes on character variability can be found in Jałoszyński (2017a, 2021a). Tetramelus, as currently defined, can be identified using the following set of co-occurring characters: hypostomal ridges running posteromesally; head ventrally lacking deep narrow longitudinal groove connecting gular plate and submentum; pronotum lacking longitudinal hypomeral grooves; pronotum broadest in front of middle; antenna in male unmodified, gradually thickened or with variously distinct tetramerous club; and tarsomere 4 in all legs lacking long distoventral lobe (for key to subgenera see Jałoszyński (2022b)). Distribution. Africa: Algeria, Cameroon, Comoros, Kenya, Lesotho, Madagascar, RSA, Swaziland, Tanzania; Asia: Asian Turkey, Nagorno-Karabakh, Nepal, “Syria”; Australia: Australia (incl. Franklin Is., Lord Howe Is., Reevesby Is., Tasmania); Caribbean: Jamaica; Europe: Albania, Andorra, Armenia, Austria, Belgium, Bosnia & Herzegovina, Bulgaria, Croatia, Czech Rep., France, Georgia, Germany, Greece, Hungary, Italy, Kosovo, Lithuania, Macedonia, Montenegro, Netherlands, Poland, Portugal, Romania, European Russia, Slovakia, Slovenia, Spain, Switzerland, European Turkey, Ukraine; North America: Canada, USA; Pacific: New Caledonia, New Zealand; South America: Bolivia, Brazil, Peru. Composition. At the time of submission of the present study there were 233 species and 2 subspecies. However, in a parallel study on Malagasy species some Stenichnini are transferred into Tetramelus (Jałoszyński, in press), which results in 17 more species included in this subgenus. All new Chinese species described below are microphthalmous, wingless and have reduced wing-related exoskeletal structures, including lack of humeral calli and the elytra strongly narrowing anteriorly; males have a large and deep median impression on the metaventrite, and all species except one have modified trochanters. All species are externally very similar, they differ in body size, pigmentation, modifications of male trochanters, and genital structures. The Chinese Tetramelus species are morphologically so close to their Western Palaearctic congeners that they can be included in the same Euconnus oblongus group (Jałoszyński 2021a).

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.
