Type material. Holotype ♂ ( Pl. 7 : Fig. 9 ): 28.I.1997, Rio Natal , 550 m, São Bento do Sul, SC [ Santa Catarina ], Brasil. A. Rank leg./ DZ 52.659/ HOLOTYPUS, Cibyra julie C. Mielke, Grehan & Koike, 2024 / ( DZUP).

Paratypes (in total 4 ♂ 1 ♀): Brazil. Santa Catarina. Same locality as holotype : 1 ♂, II.2004, A. Rank leg. ( CGCM 13.724 ) ; 1 ♂, I.2005, A. Rank leg. ( CGCM 17.636 ). São Bento do Sul , Rio Vermelho, 800 m: 1 ♀, I.1996, I. Rank leg. ( CGCM 6.427 [ HM375844 ]) ; 1 ♂, 26.I.1999, I. Rank leg. ( CGCM 4.467 ) ; 1 ♂, 28.I.2003, I. Rank leg. ( CGCM 4.684 ) .

Diagnosis. Males of C. julie sp. nov. can be readily identified by the uniform ground colour of the FW with a lighter area on the anterior portion of the postmedial band. The male genitalia cannot be confused with any other congeneric species with respect to the posterior margin of the saccus being deeply concave mesally with two protrusions laterally. The edged valvae with an inner side ribbed are unique within the genus ( Pl. 17 : Fig. 4 ; see arrows).

Description. Male ( Pl. 7 : Figs 8–9 , Pl. 11 : Fig. 11 ). Forewing length: 19–25 mm, wingspan: 37–49 mm. Epiphysis present.

Male genitalia. ( Pl. 17 : Fig. 4 , Pl. 21 : Fig. 4 ). Tergal lobes crab claw-shaped, setose basally with a spiniform process mesally. Saccus U-shaped, posterior edge bilobed, and mesally concave. Tegumen slightly S-shaped. Pseudotegumen expanded antero-ventrally, reinforced and ribbed medially. Fultura inferior rectangular, bilobed dorsally, slightly constricted meso-laterally.

Female ( Pl. 7 : Fig. 10 ). Forewing length: 39 mm, wingspan: 77 mm. Epiphysis present.

Female genitalia. Not dissected.

Distribution. Known from the type locality only ( Pl. 27 : Fig. 1 ).

Etymology. Homonym in honour of Julie Schultz, feminine. It is treated as a noun in the nominative singular in apposition.
