Body and forewings mainly dark rusty brown (Figs 2 – 5, 10 – 13). Crown and thorax dorsally dark brown, with light spots. Rostrum black (Figs 4, 12). Scutellum at both lateral margins, in centre of anterior margin and sometimes also at posterior apex with light spots (Figs 2, 10). Forewings (Fig. 18) submedially with two oblong, transverse white spots – one on clavus, touching posterior edge of wing, but not reaching claval suture, and second one between cubital and median veins, touching both; apical portion of forewing with two transparent spots, one small on cubital vein and one larger on distal end of subapical cell and apical cells I and II. Legs light brown, arolium black (Figs 3, 4, 11, 12). Hind legs darkened at base of spines, spines light (Figs 4, 12). Abdomen brown (Figs 4, 12). Male. Vertex dark rusty brown (Fig. 2). Frons coloured as vertex, lateral parts light (Fig. 5). Dark colouration from basal part of frons continuing on upper median part of postclypeus and gradually lightening towards its lower part and anteclypeus. Lateral parts of postclypeus and genae light except dark spots on genae below eyes. Lora light, with darkened margin. Antennae light brown, middle parts of leaf-like thickening of flagellum dark distally (Figs 4, 5). Pro- and mesonotum and scutellum dark rusty brown (Fig. 2). Anterior halves of abdominal sternites III – VI brown, their posterior halves whitish (Fig. 4). Female. Head uniformly dark rusty brown with light spots (Figs 10 – 13). Postclypeus with 5 – 12 lighter round spots. Anteclypeus uniformly brown. Genae black below eyes, lighter near lora. Lora dark brown with lightened margins. Antennae light. Abdomen dark, pygofer ventrally lighter (Fig. 12). External morphology. Head with crown short, evenly convex anteriorly, finely punctate (Figs 2, 3, 10, 11). Frontoclypeus weakly convex, about as wide as long. Anteclypeus with parallel sides, approximately twice as long as wide. Lora elongated-elliptical. Rostrum reaching posterior margin of thorax. Eyes convex, only in ventrolateral part slightly concave, situated on dorsolateral margins of head, their maximum diameter is along vertical axis of head. Antennae in males with apical leaf-like thickening (Figs 4, 5). Pronotum about same width as head, five times longer than head in dorsal view, strongly convex and finely punctate. Mesonotum together with scutellum roughly of same length as pronotum and also finely punctate (Figs 2, 10). Fore and mid tibiae with row of fine setae, hind tibiae with longitudinal rows of robust spines (Figs 4, 12). Forewings overlapping widely at rear because of broad appendix (Figs 2, 10). Male genitalia. Subgenital plates uniformly wide along almost their entire length and curved in middle at about 45 ° (Fig. 22). Styli elongate, pointed at distal ends, bearing row of setae directed proximally (Fig. 24). Aedeagus curved, sickle-shaped; basal part large, laterally flattened (Figs 20, 26). Female genitalia. Abdominal sternite VII elongate and pentagonal. Pygofer short and robust; ovipositor short (Figs 12, 32). Gonapophyses IX (second valvulae) relatively narrow and with small teeth (Fig. 25).	en	Gjonov, Ilia (2024): A new species of ant-attended Balcanocerus from Bulgaria (Hemiptera: Cicadellidae: Eurymelinae).
