The genus Mimaporia is characterized by the following characters: chaetosemata absent, forewing vein M₂ situated closer to vein M₃ than to the stem of vein R₅ and M₁ and aedeagus with a strongly sclerotized shaft.

Holotype: male, altitude 2800 m, 3.VIII.2004, Moxi Town, Luding County, Ganzi Tibetan Autonomous Prefecture, PR China, leg. Min Wang (SCAU).

Externally, male of Mimaporia owadai sp. n. is similar to that of the type species of the genus, M. hmong Wei & Yen, 2017, but it can be immediately distinguished from the latter externally by the bipectinate antenna, more yellowish patterns on upper side of both wings, hindwing upper side with a well-developed grayish basal zone and with submarginal band weakly developed, with only trails in cell M₁ to cell CuA₂. In male genitalia, Mimaporia owadai sp. n. can be distinguished easily from M. hmong by the tip of the valve obviously narrowing and ending with a sharper apex, praesacculus ending with a single-branched process, juxta with a median triangular process directing ventrally and with the sclerotized shaft in aedeagus narrowing in the middle part. The individual figured in Wei and Yen (2017: 544, fig. 11) is identical with the holotype in external features, which should be regarded as the same species.

Male (Figs 2–4). Length of forewing 35 mm, wingspan 62 mm. Head black; frons wide, covered with long blackish brown hairy scales and white scales; vertex covered with long blackish brown hair; compound eye black and large; antenna black, bipectinate. Thorax black; patagia covered with white scale and long blackish brown hairy scales; tegula covered with long blackish brown hairy scales and brownish scales, and surrounded by short white scales; abdomen covered with black scales and long blackish brown hair dorsally and yellowish white hair ventrally. Forewing upper side ground color black, all patterns creamy white, cilia black. Costa with a slender stripe at base; a triangle cell bar present at the base of discoidal cell; median band consisted of six patches of different sizes and shape extending from costa to cell CuA₁; postmedian band consisted of six dots of different sizes and shape extending from cell R₄ to cell CuA₁ and shifting outwards at cell R₅ and M₁; a single rounded dot present in cell R₃ at subapical zone. Forewing under side ground color blackish brown, paler at basal area; patterns similar to upper side. Hindwing upper side ground color black, all patterns creamy white, cilia yellowish white from apex to vein CuA₁, and gradually become blackish brown from vein CuA₁ to anal angle. Wing base and about half of the hindwing costa grayish brown; median zone with a single large patch extending from costa to dorsum, and are divided into smaller and slender patches by darkened veins. Two dots present at subapical zone; submarginal band poorly-developed, with only trail of paler patches extending from cell m₁ to cell CuA₂. Hindwing underside ground color similar to forewing underside, submarginal band well-developed and represented by five separated yellowish white patches extending from cell M₁ to CuA₂; other patterns similar to the upper side.

Costula (Fig. 8) presents at the junction of tegumen and vinculum, semi-circular and concaves shallowly at the middle, its surface scobinated by numerous small spines at both side of marginal area of the concave portion. Transtilla broad, slightly sclerotized. Juxta broad, U-shaped, with a triangular process at the middle part. Saccus narrow, triangular. Valva broad, gradually narrowing towards apex and ending with a rounded tip; its inner surface densely setose. Costa strongly sclerotized. Sacculus sclerotized, broad at base and narrowing towards tip. Praesacculus strongly sclerotized, ending with a triangular process directed dorsally. Aedeagus short and stout, narrowing at the middle and expanding near the apex in dorsal view. A strongly pigmented and sclerotized shaft present in the aedeagus, with middle part narrowing.

This species is currently known to occur in Luding and Wenchuan counties (Wolong) in western and northwestern Sichuan province at present.

The specific name owadai is named in honor of Dr. Mamoru Owada (Tsukuba, Japan) who provided us with assistance and some literature.

This new species flew like a Neptis (Nymphalidae) butterfly in conifer-broadleaf forest (Fig. 9) at the altitude about 2800 m. Actually, the wing maculation of forewing of the genus Mimaporia is also similar to certain species in the genus Neptis, for example Neptis alwina (Bremer & Grey, 1852), Neptis dejeani Oberthür, 1894 and Neptis philyroides Staudinger, 1887, by upper side sharing similar median and postmedian band and cell bar on forewing as well as postmedian band on hindwing. The distribution area of Mimaporia owadai sp. n. is within the distribution area of the former two species, while distribution area of M. hmong (northern Vietnam) falls within the distribution area of the last species. So we suspect that the genus Mimaporia might probably also a mimicker of the genus Neptis Fabricius, 1807 (Nymphalidae).

The genus Burmeia is a monotypic genus characterized by the following characters: antennal flagellum of male without scale, hindwing termen obviously angulate between vein M₂ and vein M₃ and in male genitalia tegumen and vinculum synscleritous. The female genitalia of Burmeia are also diagnostic and they differ from the ground plan of that of Psychostrophia in following aspects (female genitalia of other species in the genus Psychostrophia have been figured by Zhu et al. 2004): antrum membranous, while sclerotized in Psychostrophia; ductus bursae sclerotized, while membranous in Psychostrophia; corpus bursae nearly the same size of the 8^th abdominal segment, while much larger in Psychostrophia; corpus bursae with an appendix bursae of similar size, while without an appendix bursae in Psychostrophia. Regarding the characters of female genitalia given above, Burmeia is definitely a distinct genus from Psychostrophia.

28 males, 1 female, altitude 2700 m, 18–21.VII.2017, 62K, Motuo County, Linzhi Division, Xizang Autonomous Region, leg. Si-yao Huang & Shu-qin Ji; 1 male, altitude 2500 m, 15.VII.2018, Yaojiaping, Lushui County, Nujiang Lisu Autonomous Prefecture, Yunnan Province, leg.

The female genitalia are illustrated here for the first time. This little known species has not been recorded elsewhere after Minet described it in 2003 from northeastern Myanmar.

The flying period of this species in China is from early July to late July. Adults are usually found flying slowly above bushes and trees at edge of evergreen broad-leaved forest (Fig. 18) or conifer-broadleaf forest (Fig. 19) in altitude ranging from 2500 m to 3000 m along river or stream. They can fly in both cloudy days and sunny days. Males can be found sucking nutrients on human feces, damp ground, and wet stone (Figs 20–22). In 62K, Motuo County, this species was occasionally attracted to light trap in night (Fig. 23). Sometimes males can gather on damp ground (Fig. 24). In Yaojiaping, Western Yunnan, this species was found flying together with Psychostrophia nymphidiaria (Oberthür, 1893).

The genus Psychostrophia is characterized by the following characters: hindwing with cilia mostly black, except the part between vein M₁ and M₃ white; uncus long, thin and tubular for most of its length; aedeagus with a bunch of slender cornuti and coecum well developed and long.

1 female, 30.VII.2003, Jiuwanshan Natural Reserve, Rongshui Miao Autonomous County, Liuzhou, Guangxi Zhuang Autonomous Region, leg. Min Wang; 1 female, 9.VI.2014, Deqin County, Diqing Tibetan Autonomous Prefecture, Yunnan Province, leg. Jia-qi Wang.

Psychostrophia endoi is closely related to P. picaria Leech, 1897 from central and western China in external features, but it can be distinguished from it by the following combination of characters: on forewing upper side the postmedian band forming two obviously connected teeth in cell M₃ and CuA₁, pointing to termen in both sexes; the submarginal spots absent in male and the submarginal band below the subapical spot weak and represented by separated minute white dots in female; on hindwing upper side the postmedian band is obsolete and represented by white dots in male and the postmedian band ill-developed and represents by separated white dots in female; in male the genitalia valva more protruding at apex; in female genitalia the lamella antevaginalis is trapezoid in ventral view.

Length of forewing 21–22 mm, female differs from male in larger size and having submarginal series on both wings better developed. Head black; antenna filiform, black; forewing ground color black, cilia black from apex to vein R₅, white from R₅ to median portion of cell M₁ and becoming black again from median portion of cell M₁ to tornus; postmedian band white, extending from middle of the cell M₁ to dorsum, with its inner edge wavy and outer edge forming two prominent connected tooth in cell M₃ and CuA₁; subapical spot white and well-developed, oval shape; submarginal band consisted of four or five separated white dots situated from cell M₁ to cell CuA₂; hindwing ground color black, cilia black from apex to vein M₁, white from M₁ to median portion of cell M₂ and becoming black again from median portion of cell M₂ to tornus; median band white and broad, becoming wider towards costa; postmedian fascia consisted of separated white dots of different size running from apex to tornus.

Female genitalia (Figs 27, 28). Papillae anales slightly sclerotized, elliptical in lateral view, with tip rounded. Apophyses posteriores and anteriores slender; and the latter are slightly shorter than the former. Antrum well-developed and forming a strongly sclerotized chamber. Ostium bursae nearly the same width as antrum. Lamella antevaginalis strongly sclerotized, rectangular in lateral view and trapezoid in ventral view, with edge shallowly concave in the middle. Lamella postvaginalis slightly sclerotized and poorly developed, horn-shaped in lateral view. Ductus bursae membranous, long and curved medially, its anterior part near the corpus bursae slightly sclerotized and pigmented. Corpus bursae membranous, large and oval shape, scobinated with numerous small spines; its dorsal ridge near ductus bursae sclerotized and pigmented; next to the sclerotized ridge a sclerotized signum presents, consisting of larger spines.

The female of P. endoi (Figs 25, 26) is recorded here for the first time. This little known species has not been recorded elsewhere after Inoue described it in 1992 from northern Laos. The differences in the sizes of the submarginal series between females and males (Inoue 1992: fig. 1), due to sexual difference, is rather common.
