Figs 1, 2 , 21 , 33

TYPE MATERIAL. Holotype ( Figs 1 , 21 ) – ♂, Myanmar (Burma), 50 km E

Putao, env. Nan Thi village , 950 m, 11–16.V 1998, leg. Murzin & Sinjaev, slide

MWM 31683 Volynkin (Coll. MWM / ZSM). Paratypes: same data as in the holotype, 9 ♂, 1 ♀ , slides MWM 31767 (♂) , MWM 31768 (♀) Volynkin (Coll.

MWM/ZSM).

DIAGNOSIS. The new species is similar externally to B. garo ( Figs 3, 4 ) and B.

cuneonotatus (Walker, 1855) ( Figs 7, 8 ), but differs from the both species by its significantly smaller size, more orange forewing ground color and ochreous hindwings, whereas B. garo and B. cuneonotatus are significantly larger and have more reddish coloration of fore- and hindwings. The male genitalia of B. midzhan (Figs

21) differ clearly from those of B. cuneonotatus ( Fig. 24 ) and are similar to those of

B. garo ( Fig. 22 ), but differ by the much broader tuba analis, absence of medial process of juxta, slightly larger medial costal process, significantly larger dorsal subapical costal process, distally narrower distal saccular process, shorter aedeagus,

broader, sack-like subbasal diverticulum with a cluster of small cornuti, and shorter and more robust cornuti of both clusters, whereas in B. garo the juxta with a long,

conical medial process, medial costal process is slightly smaller, the dorsal subapical costal process is much smaller, the subbasal diverticulum is conical and has a small cluster of small cornuti, and the cornuti of both clusters are longer and thinner. The male genitalia of B. midzhan are also similar to those of B. complicata (Butler, 1877)

( Fig. 23 ), but differ by the broader tuba analis, broader medial costal process,

presence of distal costal process, much larger distal saccular process, and presence of two additional clusters of cornuti in vesica. In the female genitalia, B. midzhan

( Fig. 33 ) differs from B. garo ( Fig. 34 ) by its shorter apophyses anteriores, smaller lateral ostial ligula, broader and shorter postvaginal plate, stronger sclerotized appendix bursae and larger spinulose scobination of corpus bursae; from B.

complicata ( Fig. 35 ) differ by the presence of ostial ligula, much larger postvaginal plate, slightly shorter antrum, much smaller appendix bursae, much narrower corpus bursae with dense spinulose scobination medially and posteriorly (whereas in B. complicata the medial and posterior sections of corpus bursae are weakly sclerotized, rugose, with two sclerotized narrow bands), and larger signum.

DESCRIPTION. Adult ( Figs 1, 2 ). Forewing length 7.5– 8 mm, in males and 9.5

mm in females. Male antennae ciliate, female antennae filiform. Head and thorax brick orange; abdomen ochreous. Forewing ground color brick orange with reddish suffusion between veins; pattern thin, dark brown, consists of angled antemedial line,

wavy medial line connecting with antemedial line in cell, strongly curved postmedial line connected with medial line at costal and tornal margins, a series of longitudinal stripes of different length between veins in submarginal area, and marginal line presented as a row of dots between veins; costa and cilia blackish brown. Hindwings ochreous, with slight pinkish suffusion, and wide dark suffusion at apex; cilia blackish at apex and pinkish ochreous at tornus and along anal margin.

(MWM/ZSM); 6 – ♀, Borneo , Sarawak (© NHMUK) ; 7, 8 – B. cuneonotatus: 7 – ♂, Central

Thailand ( CKC); 8 – ♀, South Thailand ( CKC) .

Male genitalia ( Fig. 21 ). Uncus long, narrow, laterally flattened, curved, apically pointed; tuba analis very broad basally, scaphium thin and weakly sclerotized, subscaphium as a setose field; tegumen short and narrow; juxta shield-like; vinculum short, U-like. Valve long and narrow, costa weakly sclerotized, with short, pimplelike medial process directed ventrally and short and apically rounded subapical process directed dorsally; medial membranous lobe of valve small; sacculus narrow,

type ♀, NE India, Darjeeling ( MWM / ZSM); 12–14 – B. prominens : 12 – lectotype ♂ of B .

prominens, NE India (©NHMUK); 13 – holotype ♀ of Lyclene delicata (= B. prominens ) NE

India, Darjeeling (© NHMUK) ; 14 – ♀, NE India, Darjeeling ( MWM / ZSM) .

weakly setose, with short and apically blunt distal process curved dorsally. Aedeagus medium long, narrow, slightly curved medially, with short coecum; vesica membranous, broad, consists of large, sack-like subbasal diverticulum armed with small cluster of very small cornuti, and several smaller medial diverticula and two clusters of short, but robust, trigonal cornuti.

Female genitalia ( Fig. 33 ). Ovipositor short and broad, papillae anales quadran-

gular, with rounded angles; apophyses thin, apophyses posteriores ca. 1.5 times longer than apophyses anteriores; postvaginal plate broad and long; ostium broad,

with small lateral ostial ligula; antrum short and broad, moderately sclerotized;

anterior section of ductus bursae short, membranous, narrow. Corpus bursae globular,

with strong spinulose scobination postero-medially and round signum anteriorly;

appendix bursae small, conical, moderately sclerotized, situated latero-posteriorly.

DISTRIBUTION. Northern Myanmar (Kachin State).

ETYMOLOGY. Midzhan is a name of the beautiful woman, a character of the

Myanmar folk tale 'Maun Koun'.
