Diagnosis: C. bernardii is similar to C. miliaria in the vertex with one large black spot, long blackish setulae on palpus, wing with mottled pattern of spots. These species can be differentiated by dark brown wings with fused hyaline spots pattern on its apex, and anterior margin of male sternite 5 straight in C. bernardii , whereas pale brown wing with hyaline spots not conspicuously fused on its apex and anterior margin of male sternite 5 convex in C. miliaria .

Thorax: yellowish dark brown; mesonotum dark brown; postpronotal lobe yellow to dark brown, with an oblique row of 5–11setulae; anterior submesal spot and submesal stripe brownish; anterior dorsocentral stripe and dorsocentral stripe dark brown both merged with submesal stripe; scutellum dark brown; 2 scutellar setae; mediotergite dark brown; pleura with anterior and posterior yellowish brown stripes; proepisternum dark brown, with one longitudinal row of setulae; anepisternum upper and posterior margins with one longitudinal row of 20–27 setulae; katepisternum 7–14 setae on lower margin; and 10–18 disperse setulae; anepimeron 3– 8 setae.

Legs: yellowish dark brown. Forecoxa with sparsely dark brown spots on ventral and posterodorsal surface, covered by sparsely setulae, 2–3 apical setae on anterodorsal surface, anterior surface covered by setulae. Foretrochanter with 1 apical seta on posterodorsal surface. Forefemur ( Fig. 3 B): 3.6–4.6 times as long as wide, longitudinal row of 2–3 setae decreasing in size from base to apex on ventral surface; with ventrolateral row of setae in apical one-third, forefemur 4.0–8.5 times longer than wide. Foretibia dark brown, yellow on basal third and ventral surface. Midcoxa with 1–2 setae on posterior surface, 1 apical seta on dorsal surface and 1 row of setulae on apical margin of dorsal surface. Midtrochanter with 1 apical seta on dorsal surface; midfemur yellow, dark brown to black on middle of anterior, posterior and ventral surfaces, with 1–3 basal setae on ventral surface. Midtibia dark brown to black, yellowish on base, with 2 apical setulae on ventral surface. Hindcoxa with 1–2 setae on posterior surface, 1 apical seta on dorsal surface and 1 row of setulae on apical margin of dorsal surface. Hindtrochanter with one longitudinal row of setulae on apex of posterodorsal surface. Hindfemur with 1–3 apical basal setae on ventral surface; hindtibia dark brown to black, base yellowish; all tarsi yellowish brown.

Wing ( Fig. 4 B): dark brown with fused hyaline spots pattern on its apex; C ending before M; M becoming gradually without pigmentation through apex but reach apical margin; wing-thorax ratio 2.7–3.8; R4+5 ratio 0.4–0.5; M ratio 1.1–1.6; halter yellow.

Male abdomen: yellowish brown to black; syntergite 1+2 1.1–1.4 times as long as wide, 0.8–1.0 times as long as tergites 3–4 and 1.2–1.9 times as long as tergite 5; anterior margin of sternite 5 straight, posterior margin concave at center ( Fig. 5 B); lateral margins of tergites 1+2–5 with a row of setulae; epandrium as in Figs. 7 A–B; medial surstylus with four long setulae on posterior half; phallapodeme with an antero-dorsal fan-shaped projection; ejaculatory apodeme as in Fig. 7 C; phallus glans as in Fig. 7 D; proctiger dorsoventrally flattened, covered by strong and long reddish setulae.

Female abdomen: yellowish brown to black; syntergite 1+2 0.8–0.9 times as long as wide and 1.0–1.3 times as long as tergites 3–6, covered by sparsely setulae, lateral margin with a row of setulae; oviscape ( Figs. 8 E–F) yellowish brown, 1.9 times as long as wide and 0.9–1.3 times as long as preabdominal tergites combined; aculeus ( Fig. 8 G) 1.6–1.8 times as long as its bulky base.

Variability: frons longitudinal black stripe at center absent in some specimens; anepisternum of some specimens with 4 setae on posterior margin; midfemur of some specimens completely dark brown except apex of ventral surface yellow.

Distribution: Brazil (Bahia and Minas Gerais).

Etymology: named in honor of the entomologist Dr. Nelson Bernardi for his contribution to the knowledge of Neotropical Pyrgotidae .
