Diagnosis: Carrerapyrgota aczeli is distinguished from other congeners by the reddish yellow setae and setulae, which in the other species are mostly black; the frons with a brown convex spot on the anterior margin, in contrast to the spots of C. bernardii and C. miliaria, which are larger and not convex on anterior margin, and the absence of such spots on C. personata; the occiput in C. aczeli is dark brown to black, whereas it is yellow with a dark brown spot on the lateral margins in C. bernardii and C. miliaria, and yellowish brown with reddish lateral margins in C. personata; the palpus setulae is reddish and smaller than observed in C. bernardii and in C. miliaria, whereas in the other congeners they are blackish; the wing in C. aczeli is light brown on the upper half and pale brown on the lower, whereas it is dark brown or pale brown with sparsely hyaline spots on C. bernardii and C. miliaria respectively, or hyaline with irregular pattern of dark brown longitudinal and transversal stripes on C. personata; and also the male sternite 5, which is straight on the posterior margin in C. aczeli, but convex in other Carrerapyrgota species.
Description: Body (Fig. 1 A) yellowish to dark brown; setae and setulae reddish-yellow except labellum setulae yellow; body length 12.7–15.6 mm in male, 11.3–15.0 mm in female (holotype 14.8 mm); wing length 14.5–17.2 mm in male, 10.8–15.2 mm in female (holotype 16.3 mm).
Head (Figs. 1 B–C): frons dark brown with two lateral yellow stripes; posterior region with a brown spot convex at anterior margin; 0.7–0.9 times wider than long; eye ratio 0.5–0.6; genal-eye ratio 0.2–0.3; first flagellomere-pedicel ratio 0.8–1.2; medial vertical seta 0.4–0.6 times as long as longest diameter of the eye; lateral vertical seta divergent, 0.4–0.8 times as long as medial vertical seta; orbital seta convergent, 0.7–0.9 times as long as medial vertical seta; postocellar seta divergent, crossed with medial vertical seta; antenna: scape yellowish brown; pedicel dark brown; first flagellomere yellowish dark brown, with one longitudinal groove at center of the anterior surface, bare, 2.5–2.8 times as long as wide; arista yellow; antennal groove yellowish brown, lateral margins dark; face dark brown; parafacial yellowish dark brown, bare, 0.7–0.9 times as wide as first flagellomere; orbital sclerite yellowish to dark brown; gena yellowish brown; postgena yellowish brown, covered by sparsely setulae; occiput dark brown to black, lateral margins black; with sparsely setulae; palpus (Fig. 2 A) oval, yellowish dark brown, 0.5–0.8 times as long as first flagellomere; covered by short reddish setulae.
Thorax: yellowish brown to blackish; mesonotum brown to blackish; postpronotal lobe yellow to dark brown, with an oblique row of 8–11setulae; anterior submesal spot and submesal stripe blackish; anterior dorsocentral stripe and dorsocentral stripe blackish, both merged with submesal stripe; scutellum dark brown; 2 scutellar setae (except for single female specimen from Salesópolis with 3 setae); 1–3 pairs of central setulae convergent; mediotergite brown; pleura yellowish brown without anterior and posterior dark brown stripes; proepisternum dark brown, with one longitudinal row of setulae; anepisternum with one longitudinal row of 13–15 setulae on posterior margin; katepisternum 7–17 setae on lower margin and 13–18 disperse setulae; anepimeron with 1–2 setae and 8–11 setulae.
Legs: yellowish brown. Forecoxa with 3 to 4 apical setae on anterodorsal surface, anterior surface covered by setulae. Foretrochanter with 1 apical seta on posterodorsal surface. Forefemur (Fig. 3 A) 3.0–4.0 times as long as wide, with one longitudinal row of 8 setae decreasing in size from base to apex on ventral surface, region between setae covered by setulae more concentrated on basal half; with ventrolateral row of setae in apical one-third. Midcoxa with 6–9 setae on apical margin of anterior surface. Midtrochanter with 1 apical seta on posterodorsal surface. Midfemur with one longitudinal row of 8 setae decreasing in size from base to apex on ventral surface, with ventrolateral row of setae in apical one-third. Midtibia without distinguishable apical setulae on ventral surface. Hindcoxa with one longitudinal row of 3–4 setae on posteroventral surface, ventral surface with tufts of setulae. Hindtrochanter with one longitudinal row of 4 apical setae on posterodorsal surface. Hindfemur with two longitudinal rows of 2–3 apical setae on dorsal surface, with one longitudinal row of 1–4 basal setae on ventral surface; with ventrolateral row of setae in apical one-third.
Wing (Fig. 4 A): light brown on upper half and pale brown on lower; C reaching M; wing-thorax ratio 3.2– 3.8; R4+5 ratio 0.3–0.5; M ratio 1–1.5; halter yellowish brown.
Male abdomen: yellowish dark brown; syntergite 1+2 1.6 times as long as wide, 2.0 times as long as tergites 3–4 and 1.2–1.9 times as long as tergite 5; anterior margin of sternite 5 convex (Fig. 5 A); epandrium as in Figs. 6 A–B; medial surstylus covered by setulae; phallapodeme narrow, with an antero-dorsal hookshaped projection; ejaculatory apodeme as in Fig. 6 C; phallus glans as in Fig. 6 D; proctiger bean-shaped, laterally flattened, covered by strong and long yellow to reddish setulae.
Female abdomen: yellowish dark brown; syntergite 1+2 1.6–2.0 times as long as wide and 1.3–2.0 times as long as tergites 3–6, covered by sparse setulae, lateral margin with a row of setulae; apical margin of tergites 2–6 covered by setulae. oviscape (Figs. 6 E–F) yellowish brown, 1.8 times as long as wide on dorsal view and 0.5-0.8 times as long as preabdominal tergites combined; aculeus (Fig. 6 G) 1.3 times as long as its bulky base.
Variability: some specimens with an extra seta posterior or lateral of postocellar seta.
Distribution: Brazil (Rio de Janeiro, São Paulo, Paraná and Santa Catarina).
Etymology: named in memory of the dipterist Dr. Martin Ladislau Aczél (1906–1958) who dedicated part of his life studying the Neotropical acalyptratae fauna.
