( Figs 1–2 , 5 ) Chrysozephyrus sp. — Jiang et al . 2001: 103 , pl. 114, figs. 26–334 [misidentification] Type material. Holotype : male, VII.1995 , Baoshan , Shunchang County , Nanping City , Fujian Province , P. R . China , leg. Li-Huo Yao , dissection number JF200 ( Coll. CFJ, will be later deposited in the Lepidoptera collection of Fujian Academy of Forestry Sciences ). Description. Male. Length of forewing 21 mm . Antennae lost, but according to Jiang et al . (2001) , length is about half length of forewing. Compound eyes covered densely with whitish hair. Thorax and abdomen dorsally black and ventrally grayish white. Forewing upperside ground color blackish brown, with a intense heart-shaped orange patch in discal zone, occupying basal part of spaces 3 to 5 and extending to distal end of discoidal space and the middle part of space 2; cilia blackish. Forewing underside ground color yellowish brown; discoidal space bar slightly tint with orange and edged with white; postdiscal band white, running from costa to space 2, with the part in space 2 slightly dislocating inwards; submarginal band blackish, edges outwards with a white line and attenuating towards costa; marginal line obsolete, only visible in space 1b and 2. Hindwing upperside ground color same as forewing, with costal zone paler; vein 2 bearing a long, tail-like projection (tip lost); cilia blackish. Hindwing underside ground color as forewing; discoidal space bar slightly darker than ground color, edged with white; postdiscal band white, running from vein 8 to dorsum and strongly dislocating and curving inwards on vein 2, with part from vein 2 to dorsum forming a V-shaped pattern; submarginal band slightly darker than ground color, ornamented with two whitish lines anteriorly and posteriorly; a black rounded spot broadly encircled by orange presenting in space 2; three orange tornal spots of different shapes and sizes presenting in spaces 1b and 1c and edged with black; marginal line prominent, thin and white, extending from vein 1c to vein 8. Male genitalia. Uncus short and stout, moderately wide in dorsal view and gradually narrowing towards end. Tegumen rectangular and broad. Socii short and broad with a straight termen in lateral view, curves inwards distally in ventral and dorsal view. Branches of gnathos (falces) slender, J-shaped in lateral view and basally bearing a short and broad lateral process in dorsal view. Lateral window shallow, narrow and crescent-shape. Lateral process short and forming a small round bump. Vinculum slen- der. Saccus short and broad in lateral view and nearly trapezoid in dorsal view. Juxta slender, U-shaped. Valva broad basally and gradually narrow towards tip in lateral view, its lateral margin strongly curving medially in ventral and dorsal view; ampulla bifurcate, forming stout branches; sacculus short and rounded. Phallus slender, gently curving downwards in middle; suprazonal sheath slightly longer than subzonal sheath; aedeagus gradually tapering towards end in lateral view, with extreme distal part slightly bending downwards; vesica small, with numerous cornuti scattered on surface in basal part and gradually becaming sparse towards distal part. FIGURES 1–4. Teratozephyrus spp. adults. 1, T. yaolihuoi sp. nov. , holotype male, SE. China, Fujian (CFJ); 2, ditto , underside; 3, T. hinomaru , male, SW. China, Guizhou, TSY001 (CHSY); 4, ditto , underside. Scale=1 cm. Diagnosis. The male of T. yaolihuoi sp. nov. externally resembles only T. hinomaru Fujioka, 1994 ( Figs 3–4 , 6 , 7–8 , type locality: Chin-fo-shan, Nanchuan, Szechuan, now Mt. Jinfou, Nanchuan District, Chongqing City) from Chongqing City and Guizhou Province , southwestern China in sharing a similar intense orange patch on the forewing upperside, The new species, however, can be readily distinguished from the latter externally by the following features: 1) on the upperside of the forewing, the orange patch is less extensive and not extending to space 6 in yaolihuoi , while that in T. hinomaru is much larger and forming a long orange bar in the space 6; 2) on the underside of both wings, the ground color is yellowish brown without a reddish tint in the new species, while the ground color is ochreous brown with a reddish tint in T. hinomaru . In male genitalia, T. yaolihuoi sp. nov. can be distinguished from T. hinomaru soundly by the following characters: 1) uncus is significantly narrowing towards its tip in the dorsal view, while that in T. hinomaru is much broader throughout the whole length and only slightly narrowing at the distal end; 2) uncus, in the lateral view, is not broadening towards the base, while that in T. hinomaru is significantly broadening towards the base; 3) tegumen, in the dorsal view, is wide with the horizontal width much longer than the length of the uncus, while tegumen in the dorsal view is narrower with the horizontal width slightly longer than the length of the uncus in T. hinomaru ; 4) branch of gnathos (falx) in lateral view is curving near the distal end, while that in T. hinomaru is curving slightly before the middle point of the whole length; 5) sacculus is rounded in ventro-posterior view, while that in T. hinomaru is sharper and forming a triangular projection in the same view; 6) aedeagus has its distal end slightly bending downwards, and aedeagus vesica has shorter cornuti at its base, while the distal end of aedeagus in T. hinomaru is pointing forwards and aedeagus vesica has much longer cornuti at its base. Female. Unknown. Distribution. Currently only known from the type locality in northwestern Fujian Province ( Fig. 9 ). Etymology. This species is dedicated to the memory of Mr. Li-Huo Yao, a butterfly amateur who collected the holotype of this interesting lycaenid butterfly and devoted most of his life to investigating the butterfly fauna of Fujian Province .
