Head black with light brown lateral keels of metope, marginal keels of coryphe, lateral parts between lorae and coryphe (genae, preocular and supraocular areas), lateral keels of postclypeus and medial keel of anteclypeus lightened. Antennae dark brown. Rostrum light brown with darkened tip. Holotype also with black median keel of metope and darkening under antennae. Margins and carinae on pronotum light brown. Mesonotum, including carinae, entirely black. Tegulae widely lightened posteriorly. Tegmina black brown to black, cells in membrane lightened marginally to brownish grey, veins dark; precostal area light brown gradually widening in distal third to occupy the fore part of adjacent costal area and entire pterostigmal cell. Thorax ventrally black except metathorax, fore coxae, tibiae and tarsi dark brown, middle coxae black, femora brown, tibiae and tarsi light brown. Hind femora brown, tibiae and tarsi light brown. Abdomen brownish black with lateral and hind margins of sclerites light brown. Length of male with wings 7.1 mm, to apex of abdomen 4.7 mm.
