Description. Coloration. General coloration light brown yellowish with dark brown spots and dots ( Figs 1, 2 ). Coryphe almost totally dark brown except light yellow carinae. Pro- and mesonotum with dense dark brown dots. Episterna and epimera of meso- and metanotum dark brown. Fore and middle femora light yellow, with pair of brown or dark brown bands – basally and subapically. Fore and middle tibiae light yellow, with three dark brown bands – basally, slightly proximally of their middle, and slightly distally of their middle. Apices of tibiae brown or dark brown. Hind femora light yellow, with dark brown spots apically. Hind tibiae light yellow, with dark brown spots in its proximal half and dark brown stripes in its distal half. Apices of hind leg spines black. Abdominal sternites of males sometimes yellow or brown, with yellow hind margins. Female sternite VII yellow. Abdominal tergites light yellow, with dark brown spots. Anal tube of male and female light brown yellowish, except dark brown below the paraproct, with brown spot apically on midline. Gonoplacs yellow, with dense dark brown dots.

Structure. Metope narrow, slightly enlarged above postclypeus, with thick median and sublateral carinae ( Fig. 7 ). Median and sublateral carinae of metope joined on its upper margin. Median carina of metope running through postclypeus. Metopoclypeal suture almost straight. Lateral (marginal) keels of metope running on lateral parts of postclypeus in its upper half. Postclypeus flattened dorso-ventrally and laterally. Ocelli absent. Metope and coryphe joined at acute angle (in lateral view, Fig. 6 ). Coryphe longer than wide medially, anterior margin strongly convex, posterior margin angulately concave (in dorsal view, Figs 1, 2 , 5 ). Coryphe with median carina running from its posterior margin, but not reaching the anterior margin. Coryphe with areolet. Posterior part of coryphe (marked by shading on Fig. 5 ) almost vertically joined to its anterior horizontal part, forming obtuse angle (in lateral view). Pedicel globular, with several rows of rhinaria (around seven in each row). Pronotum shorter than mesonotum, with median carina; the anterior margin strongly convex between the eyes; its posterior margin straight. Paradiscal fields of pronotum very narrow behind the eyes. Paranotal lobes of pronotum wide. Mesonotum with median and lateral carinae. Fore wings nearly oval ( Fig. 8 ), reaching hind margin of tergite VI; without hypocostal plate. Longitudinal veins keel-shaped and simple; transverse veins absent except between CuA and Pcu; R and M starting from one point on basal cell. CuP reduced. Hind femora and tibiae longer than fore and middle ones. Hind tibia with one lateral spine in distal half and with five apical spines. First metatarsomere nearly equal in length to second and third metatarsomeres combined. First metatarsomere with two latero-apical and five intermediate spines arranged in arc. Ventral and dorsal surfaces of first metatarsomere covered by long hair-shaped setae. Second metatarsomere with only two latero-apical spines. Claws nearly twice as long as arolium of pretarsus, the latter equipped with two narrow dorso-lateral plates.

Male genitalia ( Figs 13–19 ). Hind margin of pygofer deeply concave medially (in lateral view, Fig. 15 ). Anal tube oval, with an apical concavity (in dorsal view, Fig. 19 ), gradually narrowing distally (in lateral view, Fig. 18 ). Paraproct short and wide. Phallobase wide and long, almost straight (in lateral view). Each dorso-lateral lobe of phallobase with a large tooth-shaped process subapically on its dorsal surface and with a large rounded lobe covering the ventral aedeagal hooks and bearing a small tooth-shaped process ( Figs 13, 14 : phlt). Ventral phallobase lobe thick and wide, with rows of denticles on its inner side. Apical aedeagal processes long and wide, bilobed, visible above the phallobase, with a pair of rod-shaped processes. Ventral aedeagal hooks short (nearly 1/3 of aedeagus length), pointed apically and directed to aedeagal base. Style with massive plate, hind margin convex ( Fig. 16 ). Capitulum of style small, without neck, lateral tooth finger-shaped, apical part of capitulum with two teeth ( Fig. 17 : apc).

Female genitalia ( Figs 10, 11 ). Sternum VII with hind margin bearing a pointed median projection ( Fig. 11 ). Hind margin of pygofer convex medially (in lateral view, Fig. 10 ). Anal tube narrowing apically (in dorsal view). Gonoplacs flat, much longer than anal tube, with rounded dorso-caudal angles (in lateral view, Fig. 10 ).

Measurements. Body length (from apex of coryphe to apex of anal tube in males or to apex of gonoplacs in female): males – 4.1 mm, female – 6.1 mm.

Etymology. The species is named after the collector of the type series, the renowned German hemipterist Prof. Dr. Reinhard Remane (1929–2009).
