( Figs. 55-58 , 86-87 ) Material examined. Holotype ♂ and 3 ♂ paratypes from Vietnam , Lao Cai , Sapa , Muong Hoa Ho River , 6 May 1995 , ROM 956013, D. Currie , B. Hubley , J. Swann ( ROM ). Additional paratypes : Vietnam : Lao Cai , Sapa , vicinity Sapa Post guest house, 1600 m , 5- 12 May 1995 , ROM 956003, D. Currie , B. Hubley , J. Swann , 1 ♀ ( ROM ). Lao Cai , tributary Muong Hoa Ho River , 15 km E Sapa , 926 m , 10 May 1995 , ROM 956033, D. Currie , B. Hubley , J. Swann , 1 ♀ ( IEBR ). Adult habitus. General color yellow brown patterned with dark brown. Head with dark pigment restricted to area between ocelli ( Fig. 59 ). Basal antennal segment dark apically and pale in basal third, subsequent segments dark. Pronotum pale with obscure pattern from pale brown reticulations. Wings pale amber with slightly darker veins. Femora pale in basal half, dark distally ( Fig. 61 ); tibiae and tarsi dark. Male. Forewing length 27-28 mm . Hemiterga slender, finger-like; inner margins armed with irregular row of minute spines ( Figs. 60, 65 ); dorsum and apex with a few (ca. 5-7) larger sensilla basiconica. Terga 7-9 with mesal patches of sensilla basiconica; patch on 9 extends from base of small median lobe to anterior margin of tergum; patch on 8 narrower than on 9 but extending across tergum; patch on 7 consists of a few scattered sensilla. Hair brushes present on sterna 4 or 5-7. Aedeagal sac membranous and irregularly tubular; apical third bearing a small ventral lobe; armature consists of minute to small spines covering most of venter and a smaller dorsal area; ventral patch interrupted forward of small lobe leaving a narrow bare corridor which extends almost to apex ( Figs. 63-64 ). Figs. 59-65. Kamimuria zonata adult structures. 59. Head and pronotum, 60. Male terminalia, 61. Femur, 62. Female terminalia, 63. Aedeagus, ventral, 64. Aedeagus, lateral, 65. Male hemitergal lobe, dorsal. Female. Forewing length 31-33 mm . Subgenital plate strongly narrowed to a truncate posterior margin ( Fig. 62 ). Egg. Outline oval with short stalked collar; collar moderately wide, rim flanged and margined with irregular tubercles. Chorion covered almost throughout with relatively uniform, coarse, shallow pits; micropylar area with pits more or less interrupted; ca. 18 rows of pits visible in lateral aspect and ca. 9 pits per row above micropylar line ( Figs. 88-89 ). Nymph. Unknown. Etymology. The species name refers to the distinctively banded legs. Diagnosis. This species is most easily recognized by its color pattern, large size and egg chorionic features. The uniform, relatively small pits together with the wide, stalked collar are distinctive among Thai and Vietnamese Kamimuria . The aedeagal shape ( Figs. 63-64 ) will distinguish males from related species with similar hemitergal lobes and femoral banding.
