Abstract

fetched live from OpenAlex

Genus Phytobia Lioy, 1864 Phytobia Lioy, 1864: 1313. TYPE SPECIES. — Agromyza errans Meigen, 1830. REMARKS Phytobia species are generally dark coloured in the Nearctic and Palaearctic region, but many species have contrasting yellow coloration in the Neotropical region. Most Phytobia have 3 +1 well-developed dc, a wing with vein R 4+5 ending closer to the wing tip than M 1+2 or both veins equidistant from wing tip. The frons is usually dark, sometimes paler (reddish), and the lunule is often silvery. The male genitalia usually have a broadly rounded hypandrium, and the surstyli are usually broad, lobate. A few species do not share this combination of characters and were included in a separate group, the Phytobia unica group (Boucher 2010), discussed below. Five specimens of Phytobia were collected in Mitaraka, each representing a separate species. Among them, Phytobia Mit-2 and Phytobia Mit-3 are known from female specimens only (Boucher & Pollet 2021), and their identities could not be confirmed. The other species, Phytobia Mit-1, Phytobia Mit-4 and Phytobia Mit-5 (Boucher & Pollet 2021) represent new species and are described below. Two of these new species (P. dalensi Boucher, n. sp. and P. corona Boucher, n. sp.) are part of the Phytobia unica group, along with four other previously known Neotropical species: P. unica Spencer, 1973, P. mentula Sasakawa, 1992, P. pipinna Sasakawa, 1992 and P. guatemalensis Sasakawa, 2005. This species group is characterized by the presence of only two well-developed postsutural dc, in addition to a very small third one in some species, a phallus ending in paired tubules, a well-defined cylindrical mesophallus, a narrow and elongate hypandrium, a C-shaped surstylus covered with short spines, and narrowly connected to the posteroventral margin of the epandrium. Also, the wing venation of the P. unica group is very similar to that of the subfamily Agromyzinae Fallén, 1823, with the subcostal vein joining R 1 before reaching the costa (also occurs in other Phytobia) and the distal margin of R 1 that is expanded near the junction.

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.

Not 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.
