Description. Coloration (Fig. 19). Head black, before eyes including mouthparts honey yellow to ferrugineous. Antennae sooty, base of antennomere 1 narrowly yellow. Prothorax saffron yellow, in specimen from Gaoligong Shan sepia. Meso- and metasternum, scutellum and ventral portion of abdomen sepia, elytra sooty, legs chestnut brown to sooty.
Male. Eyes large and strongly protruding, head across eyes by more than one third wider than pronotum, lateral margins of head behind eyes straight, strongly converging posteriorly. Antennae extending beyond apex of elytra by ca one quarter of elytral length, middle antennomeres moderately flattened, antennomeres 4–11 with very small, hardly visible, oval semilustrous impression. Surface of head finely imbricate-punctate, with fine, brown decumbent pubescence, matt. Pronotum slightly longer than wide, anterior margin convex, anterior corners rounded, lateral margins nearly parallel, slightly bisinuate, posterior corners rounded, posterior margin convex. Surface of pronotum sometimes with very slight mediolongitudinal carina in posterior half, finely imbricate-punctate, with fine, sparse, decumbent yellow pubescence, matt to semilustrous. Elytra parallel-sided, elytral venation absent, surface of elytra finely imbricate-punctate basally, rest of elytra finely rugulose-lacunose, with fine, decumbent yellowish brown pubescence, matt, semilustrous basally. Aedeagus as in Figs. 93–95.
Female. Eyes much smaller and less protruding than in male, head across eyes only slightly wider than pronotum. Antennae much shorter, reaching one third of elytral length, antennomeres not flattened. Last abdominal sternite as in Fig. 96.
Length (both sexes). 5.0–8.0 mm.
Differential diagnosis. Stenothemus hajeki sp. nov. is similar to Stenothemus sepiaceus Švihla, 2005 (Yunnan) and Stenothemus bezdeki Švihla, 2004 (N Laos) in the shape of the pronotum and form of the aedeagus. It differs from the former by longer antennae, which extend beyond the elytral apex, and longer divided portions of dorsal part of the aedeagus (cf. Švihla 2005), from the latter by shorter laterophyses, which do not, or very slightly, extend beyond the middle of the divided portions of the aedeagus, and the semilustrous surface of the elytra (cf. Švihla 2004).
Etymology. Patronymic, dedicated to one of its collectors, Jiří Hájek (NMPC).
Distribution. China: Yunnan province.
