Holotype ♂ (MNHN), Lao Cai / Ho-Kheou region , Tonkin [= Vietnam ] Material examined. Vietnam : Lao Cai / Ho-Kheou region , 1 ♂ ( holotype , MNHN ) . Adult habitus (translated from Klapálek 1912 ). General color yellow-brown to brown. Head yellow brown but with a black interocellar area. Pronotum brown, legs mostly brown but tips of femora darker and base of tibia pale brown. Wings brown except costal field pale. Hind ocelli much larger than anterior ocellus and nearer eyes than each other. Figs. 47-50. Kamimuria similis adult structures. 47. Male terminalia. 48. Male hemitergal lobe, lateral. 49. Aedeagus, lateral. 50. Aedeagus, dorsal. Male. Forewing length ca. 17 mm . Hemiterga long, slender and wide in lateral aspect beyond midlength and abruptly narrowed to tip ( Figs. 47-48 ); tips with sensilla basiconica. Tergum 9 with a large mesal field of sensilla basiconica; tergum 8 sensilla basiconica patch much smaller. Aedeagus membranous but armed with prominent patches of spines; basal lobe armed throughout with small spines on venter and dorsum ( Figs. 49-50 ); apical lobe armed dorsally with subapical lateral patches and an apical pair of large spine-like sclerites; venter with a median subapical spine patch. Female. Unknown. Larva. Unknown. Comments. The genitalic segments of the holotype were made available for our study through the courtesy of P. Zwick. Among known species the males are distinctive by virtue of the hemitergal lobe shape ( Fig. 48 ) and in the presence of a pair of large spine-like sclerites on the dorsal aedeagal tip ( Figs. 49-50 ).
