Review of the Sogdini of North and Central America (Coleoptera: Leiodidae: Leiodinae) with descriptions of fourteen new species and three new genera
Bibliographic record
Abstract
This paper is a review and revision of the tribe Sogdini (Coleoptera: Leoididae: Leiodinae) of North and Central America. It covers the following genera: Triarthron Märkel, 1840, with one species; Hydnobius Schmidt, 1841, with seven species; Stereus Wollaston, 1857, new for North America, with one species; Sogda Lopatin, 1961, new for North America, with two species; Kalohydnobius new genus, with three species; Macrohydnobius new genus, with six species; and Platyhydnobius new genus, with eight species. The species are inhabitants of northern and mountain forests or sandy habitats. Larvae and adults probably feed on subterranean fungi. The following new synonyms are recognized: Triarthron pennsylvanicum Horn, 1883 = T. lecontei Horn, 1868; Hydnobius luggeri Hatch, 1927 = H. substriatus LeConte, 1863; Hydnobius lobatus Hatch, 1936 = H. longidens LeConte, 1879; Hydnobius longulus LeConte, 1879 = Sogda obtusa (LeConte,1879); Hydnobius femoratus Hatch, 1936 = Kalohydnobius strigilatus (Horn, 1880); and Hydnobius stacesmithi Hatch, 1957 = Macrohydnobius matthewsii (Crotch, 1874). Hydnobius kiseri Hatch, 1936 and H. longidens LeConte, 1879 are resurrected from synonymy to valid species status. The following new combinations are established: Sogda obtusa (LeConte, 1879), ex Hydnobius; Kalohydnobius strigilatus (Horn, 1880), ex Hydnobius; Macrohydnobius contortus (Hatch, 1957), ex Hydnobius; M. crestonensis (Hatch, 1957), ex Hydnobius; M. matthewsii (Crotch, 1874), ex Hydnobius; M. simulator (Brown, 1932), ex Hydnobius; Platyhydnobius arizonensis (Horn, 1885), ex Hydnobius; and P. validus (Brown1932), ex Hydnobius. Lectotypes are designated for Hydnobius substriatus LeConte, 1863; H. pumilus LeConte, 1879; H. obtusus LeConte, 1879; H. longulus LeConte, 1879; H. strigilatus Horn, 1880 and H. matthewsii Crotch, 1874. New species are Hydnobius acarinus, H. autumnalis, Stereus arenarius, Sogda enigma, Kalohydnobius californicus, K. dentatus, Macrohydnobius montanus, M. tibiocalcaris, Platyhydnobius andersoni, P. bicolor, P. calvario, P. howdenorum, P. latigra, and P. newtonorum.

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.
