Abstract

fetched live from OpenAlex

Microphorella convoluta sp. nov. urn:lsid:zoobank.org:act: 0FD45154-9404-44C0-A0F0-2CF7DD9880AC (Figs 21, 22, 29–31, 100) Type material. HOLOTYPE, ♂ labelled:“Onefour,Alta.|49°6',110°24'| 4.VI.1955 | J.R.Vockeroth ”;“HOLOTYPE| Microphorella | convoluta | Brooks & Cumming” [red label]; “CNC| 1155851” [white label with blue border, text duplicated on underside] (CNC). PARATYPE: USA: Montana: Valley County: Duncan Rd, alkali area, 48.81786°N 107.09033°W, 21–22.vi.2023, bee bowls, M. Campano, P. Watkins (1♂, MTEC). Diagnosis. Males of this species can be distinguished from other members of the M. acroptera species group by the following combination of characters: hind trochanter with rounded, globular tubercle (Fig. 21); hind basitarsus with upturned basiventral spur-like seta (Fig. 22); halter brown; postpedicel bulb-shaped; cercus with narrow, dorsally-projecting lobe (Figs 29–31); dorsal lobe of surstylus with 3–4 prensisetae (Figs 29, 30); apical portion of phallus (distal to inflated part) elongate, with U-shaped curve protruding posteriorly. Description. Male (Figs 21, 22, 29–31): Wing length 1.6 mm. Similar to M. acroptera except as follows: Head: Face tapered ventrally, about 1.3× width of anterior ocellus at narrowest point in middle; antenna with arista-like stylus shorter, subequal to length of postpedicel. Thorax: Setae relatively weak; acrostichals biserial, short, extending to prescutellar depression; 6 dorsocentrals. Legs: Hindleg: Trochanter (Fig. 21) with tubercle rounded and globular; basitarsus (Fig. 22) with tiny, upturned, basiventral spur-like seta. Wing: As in description of M. acroptera. Abdomen: Sternite 5 with apically pointed subtriangular projection. Hypopygium (Figs 29–31): Left epandrial lamella (Fig. 30) as long as hypandrium, ventral margin mostly distinct, fading into hypandrium anteriorly; ventral epandrial process gradually tapering to bluntly pointed apex, with pointed projection arising near mid-length about 1/3 as long as process. Dorsal lobe of left surstylus (Fig. 30) with 3 blade-like prensisetae dorsolaterally near base, apex of lobe tapered to point, with rounded medioventral projection bearing curved seta (not visible in Fig. 30). Ventral lobe of left surstylus as long as dorsal lobe, with long seta near mid-length and a few smaller setae apically. Right epandrial lamella (Fig. 29) nearly as long as hypandrium, ventral margin mostly distinct, fading into hypandrium anteriorly. Dorsal lobe of right surstylus short with rounded margin, bearing 4 prominent blade-like prensisetae. Ventral lobe of right surstylus long and relatively narrow, about 3× longer than dorsal lobe, with a few setae on posterior surface. Hypandrium (Figs 29, 30) ovoid, large, as long as epandrium in left lateral view, slightly longer than epandrium in right lateral view. Phallus (Figs 29, 30) long and convoluted, with curving tubular basal portion, inflated middle portion, and long J-shaped tubular apical portion bearing tiny spines preapically. Ejaculatory apodeme about half as wide as in M. acroptera, anterior margin straight. Cercus (Figs 29–31) with broad base bearing a few prominent setae, with narrow, dorsally projecting lateral lobe and short flap-like posteromedial lobe. Female. Unknown. Distribution and seasonal occurrence. This new species is only known from Onefour in southeastern Alberta and Valley County in northeastern Montana (Fig. 100). Specimens were collected in June. Etymology. This species is named for the convoluted basal part of the phallus, a characteristic feature of the M. acroptera lineage. Remarks. The paratype was collected from an alkali area, which was presumably an arid habitat.

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.
