Description. Male ( Figs 6–8 View FIGURES 1–13 ). Palpi brown to dark brown; flagellum brown. Head and thorax brown with dark brown longitudinal medial line. Abdomen dark brown. Forewing. Forewing length: 16–17 mm. Somewhat triangular, wavy, with prominences at R 3, M 1 and CuA 2 —1A+2A and semioval concavities in-between. Wing orangish brown in medioanal area, gets darker towards costa and even more so towards outer margin; antemedial line poorly pronounced, c-shaped, dark brown; medial dot slightly blurred, dark brown; postmedial line sinusoid, slightly blurred, dark brown.Fringe dark brown. Hindwing. Somewhat trapezoid.Almost evenly brown with orangish costal area. Fringe dark brown. Genitalia ( Figs 20–22 View FIGURES 20–24 ). Tegumen reduced to membrane, laterocaudally bears pair of knob-like socii covered with setae. Vinculum ventrocaudally develops somewhat triangular or semioval saccus, slightly more sclerotized medially and mediodistally. Cucullus claw-like with widened base and blunt apex, loosely covered with setae. Sacculus somewhat claw-like with prominent blunt apex, distal half loosely covered with setae. Juxta somewhat triangular, basally connected via membrane with sacculi and vinculum, dorsally fused with phallus. Phallus cylinder-shaped with wide distal opening of vesica and apical claw-like process about as long as phallus. Vesica somewhat oval with conical ventral diverticulum bearing apically two–three elongated thorn-like cornuti and mediocaudally slender vesica ejaculatorius. Female remains unknown.

Diagnosis. Bharetta sarah sp. nov. is externally similar with Bh. owadai and Bh. hanne sp. nov. but differs from:

1) Bh. owadai with blunt elongated apex of sacculus (compare Figs 20–22 View FIGURES 20–24 and 15–17 View FIGURES 15–19 ); allopatric distribution ( Fig. 25 View FIGURES 25–26 ); and p -distance of 3.26–4.56 % in COI barcodes;

2) Bh. hanne sp. nov. with overall smaller clasping apparatus and phallus, shorter sacculus with shorter apex (compare Figs 20–22 and 23–24 View FIGURES 20–24 ).

Distribution ( Fig. 25 View FIGURES 25–26 ). Jian Nan subtropical evergreen forests in China and South China-Vietnam subtropical evergreen forests in China and Vietnam (see Olson, 2001; Dinerstein et al., 2017).

Biology. Adults were collected from February to April altitudes of 950 to 1600 m.

Etymology. The species is named after Mrs. Sarah Ruhland, the daughter of Mrs. Hanne Dossmann, and beloved stepdaughter of Mr. Josef Mooser. She studied for several years in China and helped her parents organize their trips and collecting activities in remote areas of China.
