Abstract
Scipopus (Parascipopus) nigriscapus subgen. et sp. nov. urn:lsid:zoobank.org:act: F905C84D-EBE3-49C4-9C71-226396A23583 Figs 6C, 42 Differential diagnosis Scipopus (Parascipopus) nigriscapus sp. nov. resembles S. (Pa.) fenestratus sp. nov. in having a mostly orange body, but differs by the basally orange mid and hind femora with preapical orange bands, the apical scutellar seta, and the shiny, bare orbital plate. The frontal vitta of S. (Pa.) nigriscapus is often (but not always) partially or entirely dark brown or black. Etymology The name refers to the partially or entirely dark antennal scape on many representatives of this species.

Antenna dark orange and/or black and/or light orange, flagellum usually darker apically (Fig. 42A). Palpus orange, pale microtrichose and setulose, narrow (length 4.5× width). Clypeus orange or light brown, dark brown medially, width ~1.8× height, silvery microtrichose on entire surface. Frontal vitta dull, orange and/or black, microtrichose, posterior apex strongly tapered to a point. Epicephalon light brown and/or orange, wide (width>⅔ of upper frontal vitta width at inner verticals), clearly delineated from upper frontal vitta. Paracephalon light brown and/or orange. Outer vertical seta absent, all other head chaetotaxy well-developed. THORAX. Scutum orange to reddish brown. Female cervical sclerite convex. Postpronotal lobe orange, orange setulose anteriorly. Notopleuron orange. Proepisternum orange, with dark brown or black stripe on posteroventral margin. Pleuron orange, sparsely covered in silvery microtrichosity. Tibiae black. Fore femur mostly dark brown or black, orange basally; mid and hind femora black or dark brown, orange on basal ⅛ to ½, with preapical orange band. Fore tarsomere 1 and sometimes 2 almost entirely white, hind tarsomere 1 dark brown or black with ventral golden fringe. Wing brown infuscate with indistinct, coalesced subapical hyaline spots (Fig. 42F). Apical scutellar seta present. ABDOMEN (J+ ♀). T1 with fine, yellow or orange setae. T1–6 dark brown or black, setulose. FEMALE ABDOMEN. Pleuron pale yellow or off-white, microtrichose, P1, dorsal ⅔ of P2 and dorsal half of P3–6 dark brown or black. T1+2 ~2.2 × length of T3. Oviscape dark brown or black, darker apically, white microtrichose on anterior ventral ⅓, lateral ⅓ and dorsomedian ⅛ (Fig. 6C), ~4.0–5.0× length of T6. Combined spermathecal duct length short; common duct ½ of entire duct length. Paired spermathecal duct narrow, short (2.0–3.0 × length of paired spermathecae), parallel-sided. Paired spermathecal stems narrow basally, swollen and wrinkled distally, longer than paired spermathecae. Paired spermathecae ovoid with an apical indentation. Single spermathecal duct arising from base of paired duct, narrow, ½ diameter and ≈ length as paired duct. Single spermatheca elongate, swollen apically, inornate. MALE ABDOMEN. Pleuron off-white, P1–3, dorsal half of P4–6 dark grey, pleural sac dark brown or black. T1+2 ~2.3 × length of T3. T6 short, genital fork 2.3× as long as T6, with arms converging, inner basal process angled inwards, ⅛ the length of arm. Epandrium elongate (length ~2.0 × height), short setose on posteroventral margin. Basiphallus small, crescent-shaped. Basal distiphallus short (~⅓ length of epandrium), ending in small, short (length ≈ height) phallic bulb with upper chamber with indistinct posterior round projection and rounded lower chamber. Distal distiphallus narrow, long (≈ in length to epandrium), apex very expanded, spinulose and funnel-like. Phallapodeme very broad and expanded apically. Anterior hypandrium expanded and broad. Remarks The expanded and spinulose distiphallus apex of this species is an unusual character state, not found elsewhere in Scipopus s. lat. The modified apex resembles what is referred to as the ‘glans’ in some Afrotropical genera (Marshall 2014). Distribution Mexico to Panama.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
