Bibliographic record
Abstract
1. Lathys mussooriensis sp. novo (Figs. 1-3) General: Cephalothorax dark-brown in colour and larger in-size than the previous recorded species of the genus Lathys. Total length 15.00 mm. Carapace 7.00 mm. long, 5.00 mm wide; abdomen 8.00 mm. long, 6.00 mm wide. These spiders are peculier in their body shapes look like as Theridiid, having the elongated abdomen. Detailed study of different morphological features, clearly shows that they are allied to Lycosidae. Cephalothorax: Cephalothorax is dark-brown in colour with characteristic shade, look like Hippasa (Lycosidae) with obscure border and median band longer than wide, convex, cephalic region slightly high and narrowing in front, clothed with fine hair, clypeus is low, centre is provided with a prominent and depressed fovea. Anterior row is slightly procurved and posterior row of eyes are slightly recurved. Out of eight heterogenous eyes, antero-median eyes are smaller than posteromadian eyes. Antero-median eyes are pearly white in appearance, lateral eyes are close and each situated on a brown tubercle. Strong, stout and long chelicerae are provided with two teeth in inner margin and one prominent tooth in outer margin. Strong and stout fang present. Sternum sheiledshaped, pointed behind and brown in colour. Labium as long as wide, brown, clothed with spine like hair and is provided with prominent scopulae. Legs are long, stout and strong, clothed with hair and spines having uniseriate calaminstrium on IV matatarsi and bear three tarsal claws. Male is not known till. Abdomen: Elongated, oval clothed with spine-like hair. Dorsum of the abdomen covered with blackish brown tiger-like ornamentation. Ventral side also same as like as dorsal side. Epigyne and internal ganitalia as in text figs. (2 & 3). Type species: Holotype female, paratype two females immature preserved in rectified spirit (70%). Registration numbers are 5582-83118. Type-locality: Mussoorri (Alt. about 8000 ft.), Uttaranchal, India, 21.x.2005, coil. Rakhi Roy from a corner of a wall within a heep of dry leaves. Distribution: India: Mussoorri, Uttaranchal (New record). Elsewhere: North America, Canada). Remarks: This species having some similarities with Lathus foxii Marx but differs from it in these successive characters (1) Size, length, colour and abdominal ornamentation of Lathys mussooriensis Sp. novo differs from Lathys foxii Marx (2) Size and appearance eyes greatly varies from Lathys foxii Marx (3) Prominent and depressed fovea is present in Lathys mussoooriensis Sp. novo but no such fovea in Lathys foxii Marx (4) Epigyne and internal genitalia are also structurally different. Comments: Lathys is one of the important genus under the family Dictynidae which was only found in America and Europe. Two genus as Argenna and Dictyna were recorded from India before. Lathys mussooriensis new species from Mussoorri is not only remarkable from Indian Sub-continent but also adds a new line to science of spider fauna from South East Asia.

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.
