Description. Structure ( Figs 1–8 View FIGURES 1–3 View FIGURES 4–8 ). Coryphe slightly longer than wide, with almost straight anterior margin ( Fig. 1 View FIGURES 1–3 ). Coryphe and metope jointing at right angle in lateral view ( Fig. 2 View FIGURES 1–3 ). Metope long and narrow, parallel-sided, 3.5 times as long as wide medially, with a median carina running through its whole length, and with transverse keel at metopoclypeal margin ( Figs 3 View FIGURES 1–3 , 6 View FIGURES 4–8 ). Upper margin of metope concave; lateral margins keel-shaped. Metopoclypeal suture horizontal, deeply depressed. Post- and anteclypeus with median carina ( Fig. 3 View FIGURES 1–3 ). Anteclypeus strongly flattened laterally, with protruding apex ( Fig. 4 View FIGURES 4–8 ). Rostrum long, protruding beyond hind coxae by length of 3 rd segment; 3 rd segment slightly longer than 2 nd one ( Figs 2 View FIGURES 1–3 , 5 View FIGURES 4–8 ). Ocelli absent. Scapus shortly cylindrical. Pedicel long, 2–3 times as long as scapus. Pronotum as long as coryphe medially, with median groove and with strongly protruding anterior margin and angularly concaved posterior margin. Paradiscal fields of pronotum wide behind the eyes ( Fig. 1 View FIGURES 1–3 ). Paranotal lobes of pronotum long and wide ( Fig. 2 View FIGURES 1–3 ). Mesonotum twice longer than pronotum, with fine median carina. Tegulae large. Fore wings slightly protruding beyond apex of ovipositor, with a wide subcostal field in its basal third and almost no transverse veins; clavus as long as whole wing, open ( Figs 2 View FIGURES 1–3 , 8 View FIGURES 4–8 ). Basal cell elongate and narrow. Fore wing vein branching sequence ( Fig. 8 View FIGURES 4–8 ): R 4, firstly furcating closely to basal cell, posterior branch (R 2) soon after furcating twice; M 9–10, firstly furcating closely to basal cell, anterior (M 1) and posterior (M 2) branches again furcating near to wing middle; CuA 2, furcating near to wing middle. Pcu joint first anal vein (A 1) after wing middle. Hind wings as long as fore ones. Legs not flattened neither foliated. Hind tibia with eight spines apically and three lateral spines—small one in the middle and two larger ones subapically. First and second metatarsomeres short, nearly equal in length, with sparse long setae ventrally. First metatarsomere with two latero-apical and five intermediate spines. Second metatarsomere with only two latero-apical spines. Third abdominal sternite large. Hind margin of sternite VII concave laterally and convex medially ( Fig. 7 View FIGURES 4–8 ).

Coloration ( Figs 1–3 View FIGURES 1–3 ). General coloration yellowish brown to dark brown. Coryphe dark brown, with yellowish light brown median part and black anterior and lateral margins. Metope brown to dark brown above clypeus.

Anteclypeus, claws, and anterior connective laminae of gonapophyses VIII dark brown. Pronotum dark brown except yellowish light brown median line. Paranotal lobes of pronotum with black lower margins. Mesonotum dark brown laterally and yellowish light brown medially. Fore wings yellowish light brown to brawn, with dark brown to black marginal cells and cells between radial veins and with dark brown to black large oval spot at the fork of first and second branches of median vein (M 1 and M 2) on each wing. Clavus dark brown medially. Hind tibiae brown to dark brown. Abdominal sternites IV–VI and sternite VII medially brown to dark brown. Hind margin of sternite VII black laterally ( Fig. 7 View FIGURES 4–8 ). Gonoplacs light yellow.

Female terminalia. Anal tube twice as long as wide, weakly narrowing apically, with rounded apex. Gonoplacs large, flat, triangular-shaped, each with seven large teeth at apex ( Fig. 2 View FIGURES 1–3 ).

Total length. 8.0 mm.

Etymology. The species is named in honor of Dr. Edmund Schmidt who made important contribution to our knowledge of planthoppers of tropical Africa.
