Adult habitus. General color dark brown to black. Head almost entirely dusky to black but darker on lappets and between ocelli, especially in recently emerged specimens ( Fig. 1 ); tentoria and M-line pale. Wing membrane dark brown, veins darker. Femora bicolored with pale basal and dark apical half ( Fig. 4 ); tibiae and tarsi dark brown.

Male. Forewing length 16-18 mm. Hemiterga slender, fingerlike, and bearing a partially hidden concave excavation along inner margins ( Figs. 2, 8 ); sensilla basiconica absent or rare on tips. Tergum 9 with a mesal patch of sensilla basiconica; tergum 8 with a smaller patch. Setal brushes present on sterna 4-6. Aedeagal sac membranous with apex expanded in lateral aspect and mesally constricted in ventral aspect ( Figs. 6-7 ). Armature consists of patch of fine to small spines covering most of sac venter, but apex and base bare.

Female. Forewing length 20-21 mm. Subgenital plate wide, but scarcely projecting over basal third of sternum 9 ( Fig. 5 ).

Egg. Outline oval with short medium width collar. Collar rim flanged and irregularly scalloped. Chorion covered throughout with obscure, shallow pits ( Figs.70-71 ).

Larva. Unknown.

Etymology. The species name refers to the dark adult habitus.

Diagnosis. Among Thai and Vietnamese Kamimuria , this species is distinctive by virtue of its dark habitus. The excavated inner margins of male hemiterga ( Figs. 2, 8 ) are also distinctive and the egg ( Fig. 70 ) will allow separation from known species.
