Description. Measurements in mm (n = 4): length of body: 7.00–7.60 (mean 7.23); width of body: 4.70–5.10 (mean 4.84); height of body: 3.20–3.50 (mean 3.30); width of head: 1.97– 2.07 (mean 2.02); interocular distance: 1.40–1.45 (mean 1.43); width of apex of pronotum: 2.30–2.40 (mean 2.36); width of base of pronotum: 4.02–4.12 (mean 4.09); length of pronotum along midline: 1.80–1.85 (mean 1.83); length of elytra along suture: 5.10–5.60 (mean 5.30).

Body oval and strongly convex ( Fig. 3 View Figs 1–5 ). Head dark reddish brown to dark brown. Mandibles reddish-brown, apex black. Maxillary palps reddish-brown, with apical palpomere dark brown. Antennomeres I–V yellowish-brown, sometimes IV–V partially darkened, VI–VII blackish-brown, VIII–XI black. Pronotum brown to blackish-brown, margins black. Scutellum dark brown, basal margin black. Elytra dark brown to blackish-brown, with two pairs of yellowish-brown spots. Venter dark brown to black, with hypomera and last abdominal ventrite partially brown. Legs reddish-brown, with at least basal half of femora dark brown.

Head. Vertex weakly convex, covered with sparse punctures, becoming coarser and denser toward sides. Frontal suture V-shaped, reaching anterior margin, coronal suture rather long. Frons flat, suddenly depressed at anterior margin, covered with dense punctures. Clypeus very narrow and trapezoidal. Anterior margin of labrum with tooth-like projection. Mandibles with two sharp apical teeth and deep excavation for apical maxillary palpomere on outer side. Maxillary palps 4-segmented, with apical palpomere slightly widened, truncate apically. Antennae reaching pronotal base; antennomere I robust, longest; II shorter than III; III longer than IV; VIII–XI strongly widened and flattened, each distinctly wider than long, XI about 1.24 times as long as wide ( Fig. 22 View Figs 22–28. 22–24 ).

Pronotum. Lateral sides rounded, widest at base, thence strongly narrowed anteriorly; anterior angles strongly produced ( Fig. 8 View Figs 6–10 ). Anterior and lateral margins bordered, lateral margins well visible in dorsal view. Trichobothria absent on both anterior and posterior angles. Disc covered with sparse or moderately dense punctures; lateral sides covered with much larger and denser punctures; interspaces covered with fine and sparse punctures. Scutellum distinctly wider than long, narrowed posteriorly.

Elytra. Lateral sides slightly widened posteriorly, widest beyond middle, thence roundly narrowed posteriorly. Humeral calli well developed. Disc covered with irregular, coarse and large punctures except humeri, elytral suture and lateral margins; punctures partially arranged in double rows; interspaces covered with fine and sparse punctures. Epipleura visible in lateral view except near base. Hind wings well developed.

Venter. Hypomera weakly rugose, with a few punctures near anterolateral corners of prosternum. Prosternum covered with coarse and dense punctures bearing long setae; prosternal process enlarged apically, bordered laterally, with sparse punctures. Metasternum covered with small and sparse punctures in median region, large and dense punctures in lateral region. Abdominal ventrites covered with sparse or dense punctures bearing short setae.

Legs. Moderately robust. Tibiae widened apically, with tooth-like projection. Fore legs with tarsomere I distinctly narrower than III in both sexes. Tarsal claws appendiculate.

Genitalia. Aedeagus rather thick, parallel-sided, strongly narrowed before apex, setose apicolaterally, with apical process short and elongate-oval in dorsal view; strongly curved, with apical process short in lateral view ( Fig. 23 View Figs 22–28. 22–24 ). Spermatheca C-shaped, thin and apex rounded ( Fig. 24 View Figs 22–28. 22–24 ).

Differential diagnosis. Gonioctena (A.) jindrai sp. nov. is similar to G. (A.) eburoides , G. (A.) flavoplagiata , G. (A.) mausonensis , and G. (A.) truncaticornis sp. nov. in strongly widened and flattened last four antennomeres and two pairs of yellowish brown spots on dark elytra. However, it can be distinguished from G. (A.) eburoides and G. (A.) flavoplagiata by aedeagus with apical process short and elongate-oval (moderately narrowed to blunt apex in G. (A.) eburoides and very thin and parallel-sided in G. (A.) flavoplagiata ). Gonioctena (A.) mausonensis differs in reddish brown venter while G. (A.) truncaticornis sp. nov. differs in rather truncate apex of last antennomere.
