Diagnosis: C. miliaria is differentiated from C. bernardii by pale brown wing with hyaline spots not conspicuously fused on its apex and anterior margin of male sternite 5 convex. From C. aczeli it can be distinguished by the black setae and setulae, and from C. personata by the presence of a larger not convex spot on the anterior margin of the frons.

Redescription: Body ( Fig. 9 A): yellowish brown; setae and setulae black except labellum setulae yellow; body length 8.9–9.4 mm in male, (holotype 9.4 mm), 6.5–9.5 mm in female; wing lenght 7.8–8.1 mm in male (holotype 8.0 mm), 7.8–10.9 mm in female.

Head ( Figs. 9 B–D): vertex with a large black spot; frons anterior region dark brown, posterior region yellowish brown, with one longitudinal black stripe on center, absent in some specimens, frons 0.5–0.6 times wider than long; eye ratio 0.4–0.6; genal-eye ratio 0.3–0.5; first flagellomere-pedicel ratio 1.4–1.8; medial vertical seta convergent, 0.2–0.3 times as long as longest diameter of the eye; lateral vertical seta divergent, 0.3–0.5 times as long as medial vertical seta; orbital seta convergent, 0.7–0.9 times as long as medial vertical seta; antenna: scape and pedicel yellow; first flagellomere yellowish to dark brown, bare, 2–2.5 times as long as wide; arista yellow; antennal groove yellowish, with two dark spots on lower margin; parafacial yellowish, bare, 0.3–0.4 times as wide as first flagellomere in male and 0.6–0.8 in female; sclerites orbital yellowish; gena and postgena yellow; occiput yellow, lateral margins with a dark brown spot, with sparsely setulae; palpus ( Fig. 2 C) oval, yellowish, 0.5–0.8 times as long as first flagellomere, covered by large blackish setulae.

Thorax: yellowish brown; mesonotum yellowish brown; postpronotal lobe yellow, with an oblique row of 6–11setulae; anterior submesal spot and submesal stripe brownish; anterior dorsocentral stripe and dorsocentral stripe dark brown both merged with submesal stripe; scutellum yellow to brown, 2–3 scutellar setae; mediotergite brownish; pleura yellowish brown with anterior and posterior dark brown stripes; proepisternum brownish with one longitudinal row of setulae; anepisternum upper and posterior margins covered by a row of 18–32 setulae; katepisternum 6–9 setae, and 15–20 setulae; anepimeron 4–10 setae.

Legs: yellowish brown. Forecoxa with 3 apical setae on anterior surface, 1 apical seta on ventral surface, anterior surface covered by setulae. Foretrochanter with 1 apical seta on dorsal surface. Forefemur ( Fig. 3 C): 3.5–4.5 times as long as wide, with one longitudinal row of setae decreasing in size from base to apex on ventral surface; with ventrolateral row of setae in apical one-third. Midcoxa with 3–5 apical setae on anterior surface. Midtrochanter with 1 apical seta on dorsal surface. Midfemur yellowish on apex of ventral surface, with 1 basal seta on ventral surface, with ventrolateral row of setae in apical one-third. Midtibia with 2 apical setulae on ventral surface. Hindcoxa with 3 apical setae on ventral surface. Hindtrochanter with a row of 3–6 setae on posterior surface. Hindfemur with ventrolateral row of setae in apical one-third.

Wing ( Fig. 4 C): pale brown wing with hyaline spots not conspicuously fused on its apex; C ending before M; M becoming gradually without pigmentation through apex but reach apical margin; wing-thorax ratio 2.0– 3.4; R4+5 ratio 0.4–0.5; M ratio 1.1–1.5; halter yellowish brown.

Male abdomen: dark brown; syntergite 1+2 1.1–1.7 times as long as wide and 1.3 times as long as tergites 3–4 and 1.3–2.0 times as long as tergite 5; posterior margins of sternites 1+2–5 concave at center; lateral margins of tergites 1+2–5 with a row of setulae; anterior and posterior margin of sternite 5 with a central concavity ( Fig. 5 C); epandrium as in Figs. 8 A–B, as high as long in profile; medial surstylus covered by a row of short setulae on posterior half; phallapodeme with an antero-dorsal inverted V-shaped projection; ejaculatory apodeme as in Fig. 8 C; phallus glans as in Fig. 8 D; proctiger dorso-ventrally flattened, covered by strong reddish setulae.

Female abdomen: yellowish brown; syntergite 1+2 0.9–1.3 times as long as wide and 1.0–1.6 times as long as tergites 3–6 and 0.7–0.8 times as long as preabdomen; oviscape ( Figs. 10 E–F) yellowish, 1.5 times as long as wide and 0.9–1.3 times as long as preabdominal tergites combined; aculeus ( Fig. 10 G) 1.6–1.7 times as long as its bulky base.

Variability: Some specimens have lack the central longitudinal black stripe on the frons, and some specimens have four setae on the posterior margin of the anepisternum.

Distribution: Argentina (Salta, Catamarca, Tucumán and Santiago Del Estero), Brazil (Pará, Goiás, São Paulo and Mato Grosso do Sul).
