DIAGNOSIS. An unmistakable species. The forewing pattern resembles that of

B. hypoprepioides (Walker, 1862) ( Fig. 17 ) and B. syntypica Swinhoe, 1906 ( Fig.

18), but B. cernyi ( Figs 15, 16 ) differs clearly from the both species by its bright yellow wing coloration and smoothly curved medial line of forewing. The male and female genitalia of B. cernyi ( Figs 28 , 39 ) are very different from those of B.

hypoprepioides ( Figs 31 , 42 ) and B. syntypica ( Figs 32 , 43 ) and more close to those of Barsine peraffinis (Fang, 1991) comb. n. ( Fig. 19 ) and Barsine collina (Černý,

2016) comb. n. ( Fig. 20 ), but differ from B. peraffinis ( Fig. 29 ) by the presence of medial costal process, presence of a long pointed distal costal process, absence of a dorsal lobe of distal saccular process, and narrower vesica with four bunches of robust spines (whereas in B. peraffinis a medial costal process is absent, a distal costal process is very short and broadly trigonal, the distal saccular process is bilobate with a long dorsal lobe, and the vesica is significantly broader, with a long row of robust spines and a short row of short trigonal cornuti); from B. collina ( Fig.

30) differ by the presence of medial costal process, absence of pointed costal process directed dorsally, much broader distal section of costa with a slenderer distal process, absence of a dorsal lobe of distal saccular process, and narrower vesica with four bunches of robust spines (whereas in B. collina a medial costal process is absent, the costal process directed dorsally is present, the distal saccular process is bilobate with a long dorsal lobe, and the vesica is broader, with a cluster of short trigonal cornuti only). The female genitalia of B. cernyi ( Fig. 39 ) differ from those of B. peraffinis ( Fig. 40 ) and B. collina ( Fig. 41 ) by the longer apophyses anteriores,

34 – B. garo sp. n., paratype, NE India; 35 – B. complicata, Malaysia, Cameron Highlands ;

36 – B. cuneonotatus, NE Thailand; 37 – B. wernerthomasi sp. n., paratype, NE India ; 38 –

B. prominens, NE India; 39 – B. cernyi sp. n., paratype, N Myanmar ; 40 – B. peraffinis ,

Central Vietnam.

rounded lateral lobes of antrum directed laterally, shorter ductus bursae, more robust spinulose scobination of corpus bursae, and smaller appendix bursae

(whereas in B. peraffinis and B. collina the apophyses anteriores are shorter, the lateral lobes of antrum are pointed apically and directed posteriorly, the ductus bursae is longer, the spinulose scobination of corpus bursae is weaker, the appendix bursae is much longer).

DESCRIPTION. Adult ( Figs 15, 16 ). Forewing length 10 mm, in males and 11

mm in females. Male antennae ciliate, female antennae filiform. Body dark yellow,

thorax with two large lateral black spots. Forewing ground color bright yellow;

pattern black, consists of a subbasal spot and three strokes, W-like waved antemedial line, S-like curved medial line connected with antemedial line in the cell, comma-like discal spot, S-like curved postmedial line and lengthwise strokes on veins in outer part of forewing; cilia bright yellow. Hindwing pale yellow,

medial band diffuse, grey, slightly wavy; submarginal area with intense black suffusion on veins and slight black suffusion between veins; cilia pale yellow.

Male genitalia ( Fig. 28 ). Uncus long and narrow, laterally flattened, medially slightly broadened, apically pointed; tuba analis membranous; scaphium thin, moderately sclerotized; subscaphium not developed; tegumen medium long and broad;

manica weakly sclerotized, setose; juxta broad, rectangular; vinculum short, V-like.

Valva elongated, distally broadened; costa S-like curved, distally broadened, with long, narrow, apically pointed distal process; medial costal process short and broad,

trigonal, with pointed apex; sacculus narrow, setose; distal saccular process elongated,

with broad base and rounded tip; aedeagus long, narrow, slightly S-like curved;

vesica globular, with two large bunches of robust spines, broad subbasal diverticulum having a small bunch of spines, and a broad apical diverticulum with a row-like cluster of spines.

Female genitalia ( Fig. 39 ). Ovipositor short, conical; papillae anales rectangular with rounded angles; apophyses of equal length, long and thin. Antrum broad, with short, rounded medial concavity and lateral rounded lobes directed laterally; ductus bursae long, dorso-ventrally flattened, heavily sclerotized, with weaker sclerotized lateral margins. Corpus bursae sack-like, with strong spinulose scobination medially and posteriorly; its anterior section with granulation; appendix bursae very short, conical.

DISTRIBUTION. The species is known only from its type locality, northern

Myanmar (Kachin State).

ETYMOLOGY. The name is dedicated to Dr Karel Černý, a famous expert in the Oriental Arctiinae and author’s friend.
