Description, male. Body length 8.5–9.5 mm, width 3.2–3.5 mm. Body slender, weakly convex, with dull shine; legs and antennae red-brown. Head widest at level of the eyes. Eyes large, convex. Ratio of head width at eyes to distance between eyes: 1.7. Genae regularly strongly rounded. Lateral margin of head with obtuse emargination between gena and clypeus. Punctation of head moderately coarse and dense: diameter of punctures subequal to distance between punctures. Antennae long (reaching almost 1/2 of elytral length), with 4 apical antennomeres extending beyond base of pronotum. Pronotum weakly transverse (1.2 × as wide as long), 1.4 × as wide as head, widest at middle, rarely slightly before middle. Lateral margins of pronotum weakly rounded, not sinuate in base. Anterior margin straight; base straight, sinuate in middle. Anterior angles obtuse, narrowly rounded on apex; posterior angles right, distinct on apex. Hypomera with very fine irregular wrinkles. All margins narrowly beaded. Disc regularly weakly convex, sometimes with small impression on each side near base. Punctation of disc moderately coarse, not dense (diameter of punctures visibly smaller than distance between punctures), punctures round. Hypomera with longitudinal wrinkles, very narrowly and weakly flattened laterally. Elytra weakly convex, elongated (1.6 × as long as wide), 1.25 × as wide and 2.5 × as long as pronotum, 1.8 × as wide as head. Strial punctures merged in interrupted furrows. Elytral intervals flat, without tubercles or with very small, weakly visible tubercles on apex. Epipleural carinae wide and distinctly visible in dorsal view throughout entire length; epipleura with inner narrow carinae reaching elytral apex. Lateral margins of elytra straight (not sinuate) apically. Ventral side of body bare. Metaventrite with same punctation as pronotum. Abdominal ventrites with fine and sparse punctation; ventrite 1 with very dense punctation and dense hair brush at middle; sometimes 2nd ventrite also with short hair brush; ventrite 5 without transverse depressions, bare, completely beaded on apex. Legs. Inner side of femora smooth, without punctation. Tibiae narrow, straight. Protibiae with 3–4 teeth; mesotibiae with 4–5 teeth; metatibiae with 3–5 very small teeth. Each pro- and mesotrochanter with single hair and very short brush of setae; metatrochanters with dense hair brush.

Description, female. Body length 9.8–11.4 mm, body width 3.9–4.5 mm. Body more robust. Pronotum more transverse. Antennae shorter than in male, with 3 (rarely 4) antennomeres extending beyond base of pronotum, reaching 1/4 of elytral length. First and second abdominal ventrites without hair brush. Anal ventrite without depressions, only flattened in middle. Strial punctures on elytra like dotted lines.

Etymology. The name is derived from Thracia (province of the Roman Empire, presently the European Turkey).

Bionomics. Imagoes were found between 17:00 and 23:00 on Quercus robur   covered with lichens.

Diagnosis. Differences from the nominate subspecies are shown in the key.
