FROM CHINA (II)

OKANOMasao

The present paper deals with five Chinese species belonging to the families Hespe;iidae, ’ and Nymphalidae. Among ’them one specie.s and two subspecies are described as new to science and one subspecies is newly.added to the fauna of China. The specimens mentioned in this paper are preserved irt’ my collection.. In preparing this paper, 1 wish’to express my gratitude to Prof. Dr. TAKAsHi SHIR6zu, Mr. KIKuMARo OKANo, Mr. JozABuRo’ OHKuRA, Mr. SATosHI KolwAyA, Mr. YuKiNoBu ABE and Mr. SHuNzo KAMMuRi for their’kindness rendered in varlous ways.

HESPERIIDAE

Satarupa omeia・ sp. nov.

(Pl. 1, figs. 1, 2, 8; Text-fig. 1, S genitalia)

At first glance,.this new species most closely resembles S. fodimosibia STRAND in almost similar appearance, but is separable in the folloWing characters: ’ .Male. On the forewing the cell spot and the spot in space 2 are smaller; the spot in space 3 is larger; the spot in space 2’ is placed .nearer to the spot in space 3 than to the cell spot as in∫. gopala.〃za]’asra FRuHsToRFER;the.spo七s in space lb ・are rather smaller. On・the hindwing the’ 垂盾唐狽р奄唐モ≠戟@black spots in spdces 3 to 5 are.

Specimens examined: 2 6, 2ufushan, Shandong (Shantung), N. China, June, 1981; 16, Dongk6u, Kunming, Yunnan, May, 1982; 16, Shilin, Yunnan, August, 1981 (S. Koiw4yA);46, Dali (Tali), Yunnan, 1981.. This species is new to the fauna bf N. China, but it has already been recorded from Yunnan by KoiwAyA (1980). Among the specimens recorded qbove, ’the males from Shandong are identical with those from Yunnan. The female is sepa- rable from’ the male in having the forewing termen more strongly convex. As compared with the W. Chinese male figured bY LEEcH (1893), the Shandong apd Yunnan specimens are smaller (length of forewing, 16.0-18.5mm. against 19.5 mm.) ; the streaks and bands pn the inrier and central areas of the hindwing below are white or faintly yellowish White, while in the LEECH’s male they are yellow. The Chinese male figuted by SEiTz. (1909)’is similar to the-LEE・CH’s male in size, colouration and markings. On the length of forewing i耳.subsp.. sinica, STIcH肌 (1928) says, it is “bis 22 mm.”i

This is a weil mqrked subsp.ecies ot Acraea issori.a. (HUBNER) bceurring in Yunnan. Closely related to subsp. sordibi e (FRuHsToRFER), but i. s easily destinguished by the, following characters, Male. On the upper surface the ground 6010ur is paler; the black bordering of both the wings is generally broader; the forewing blagk spots q.re generally morc strongly developed;adiscal series of bla¢k『pots.apPear on..the hiヰd彬ing in the extreme form (Pl. 1, fig. 7). On the under surface the hindwing ground cglour is whiti.sh, while in subsp. soraice...it is pale, yellgw.; the s.ubmarginal orgnge band is narrower, and’its inher side is’more strohgly margined With black than in subsp. soraice.
