This species is very similar in colour to R. wirthi and females appear to be indistinguishable from the latter. Males are distinguished by base of M 1 and M 2 ranging from short to long coalescence, eight short, slender dorsocentral setae, prescutellar depression without pruinescence and clasping cercus broad and rounded apically. Description. Wing length 3.6–4.2 mm. Male. Face and gena with bluish pubescence. Ocellar setae divergent, weak, shorter than pprn; vertical seta weak and short as ocellar seta. Antenna with short stylus, longer than length of postpedicel; postpedicel ovate, shortly prolonged apically. Length of proboscis four-fifths head height. Pleura with blue pruinescence; prescutellar depression without pruinescence; several acr, very short, confined to anterior to first pair of dc; 8–10 dc, slender and weak, prescutellar seta stronger; 1 pprn; 1 presut spal with several setulae; 2 npl with several anterior setulae; 0 psut spal; 1 pal; 2 sctl and numerous short to long setulae on disc and margin, outer and inner marginal setulae often nearly half length of apical seta; laterotergite with patch of pale setae; antepronotum with several setulae; lower proepisternum with pale setae. Wing infuscate; cell dm pointed apically, with base of M 1 and M 2 coalesced basally for short to long distance, subequal in length to crossvein dm-m. Legs dark brown; coxae with bluish pruinescence. Hind tibia with distinct ventral setae, longer than half width of tibia. Abdominal tergites dark brown, with bluish pruinescence; bearing short black setae. Terminalia (Fig. 17): Hypandrium slightly shorter than epandrium, apex rounded; without setae. Phallus slightly curved; membranous distiphallus with pair of elongate, narrow lateral extensions, bearing short, apical sclerotized plates. Cercal plate with several long setae; clasping cercus broad, apical margin rounded; stout, thickened setae on dorsal margin, with setae along upper inner face and long dense setae on inner base margin. Female. Similar to male. Etymology. This species is a patronym, honouring the late Canadian empidid specialist, J.G. Chillcott. Distribution. This species is known from Arizona and New Mexico (Fig. 32). Remarks. The type specimens of R. wirthi was a mixed series, with the holotype discovered to be conspecific with R. retroversus. The naming of a new species was required for several male paratypes of R. wirthi (Chillcott 1961, fig. 19), not conspecific with the holotype. See “Notes on types” under R. wirthi for further details.
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.
