Abstract
Indopolystoma viridi n. gen. n. sp. (Figs. 2, 3 and 4; Table 4) urn:lsid:zoobank.org:act: E314A3B7-A5CE-48BA-9A21- B100556A34B9 Synonym: Polystoma sp. of Verneau et al. [51], Badets et al. [2] and Héritier et al. [22]. Type-host: Rhacophorus viridis (Hallowell). Now Zhangixalus viridis (Hallowell) [21, 27]. Site: Bladder. Type-locality: Tokunoshima Island, Kagoshima prefecture, Japan. Collector: Professor Hideo Hasegawa, Department of Biology, Oita Medical University, Hasama, Oita 879-5593, Japan. Type-specimens: Holotype (MNHN HEL1173) and 10 paratypes (MNHN HEL1174 – HEL1183) deposited in the Parasite Collection, Muséum national d’ Histoire naturelle, Paris, France and four paratypes (NMB P512 – P515) in the Parasitic Worm Collection, National Museum, Aliwal Street, Bloemfontein, South Africa. Etymology: The name viridi refers to the species name of its host. Description Description based on 15 unflattened specimens stained in carmine and mounted in Canada balsam. Body elongate, total length 8550 (5532–11,907), including haptor; greatest width 2112 (1534–2859); width at vagina 1481 (1175–1800). Tegument smooth. Haptor sub-rectangular, 773 (526–1354) long, 1184 (588–1592) wide. Haptor/total body length ratio 0.09 (0.05–0.17). Suckers 333 (242–423) in diameter. Hamuli 313 (276–373) long; with hook 66 (48–74) long (Fig. 3A–H). Marginal hooklet C1 40 (31–44) long; C2–C8 21.5 (16–31) long (Fig. 4A–C). Mouth ventral, sub-terminal and surrounded by false oral sucker; false oral sucker 394 (266–465) wide. Pharynx pyriform, 210 (124–268) long, 209 (164–244) wide. Oesophagus not visible. Lateral intestinal caeca with medial diverticula branched lacking prehaptoral and haptoral anastomoses. Testis not visible hidden by digestive tract and vitellaria. Seminal vesicle prominent and packed with sperm. Genital bulb slightly sclerotized, medio-ventral, 105 (67–124) in diameter, with eight to nine sclerotized genital spines; genital spines 40 (27–49) long. Ovary prominent, sinistral and packed with oocytes; ovary 775 (577–925) long, 401 (286–536) wide. Ootype well developed. Genito-intestinal canal present on the same side of body as ovary, joining intestinal caecum posterior to ovary. Uterus confined to area anterior to ovary holding one egg; egg 241 (191–268) long, 125 (74–165) wide. No intrauterine development of eggs observed (Fig. 2). Differential diagnosis Indopolystoma viridi is similar to I. elongatum and I. parvum in terms of body shape, haptor/total body length ratio and shape of haptoral sclerites. However, it differs from the same two species by the general morphology of intestinal caeca and its body size (8550 µm vs. 14,791 µm for I. elongatum and 4714 µm for I. parvum). It differs from all other species of Indopolystoma in having intestinal diverticula without anastomoses.
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.
