Diagnosis. Among all Cibyra spp., C. jurate sp. nov. shares only the interrupted baso-central band on the male FW with members of the monoargenteus species-groups ( C. tessellata, C. elyana sp. nov., C. regina sp. nov., and C. jane sp. nov.), but it is easily distinguished by attributes of the male genitalia, especially the two digitiform meso-ventral diverticula on the phallus, whereas this is a single structure in the monoargenteus species-group.

Description. Male (Pl. 7: Fig. 2, 3–4, 7, Pl. 11: Fig. 10). Forewing length: 13–16 mm, wingspan: 26–33 mm. Epiphysis present.

Male genitalia (Pl. 17: Figs 1–3, Pl. 21: Fig. 3). Tergal lobes with a protrusion posteriorly. Posterior margin of saccus with mesal portion projected, latter concave or V-shaped. Tegumen slightly S-shaped.

Female (Pl. 7: Figs 1, 5–6, Pl. 13: Figs 11–12). Forewing length: 17–28 mm, wingspan: 33–53 mm. Epiphysis present.

Female genitalia. (Pl. 23: Figs 11–12, Pl. 24: Fig. 11). Lamella antevaginalis with mesal third less sclerotised then lateral; latter postero-dorsal edge densely sclerotised and spiniform. Ductus and corpus bursae with 2/5 and 3/5 of its total length.

Distribution. Central and eastern Minas Gerais, Rio de Janeiro, and eastern São Paulo, southeastern Brazil, at altitudes between about 700 and 1400 m (Pl. 27: Fig. 2).

Etymology. Homonym in honour of Jurate De Prins, a prominent lepidopterologist. It is treated as a noun in the nominative singular in apposition.
