Description. Measurements in mm (n = 1): length of body: 6.30; width of body: 4.30; height of body: 2.80; width of head: 1.85; interocular distance: 1.20; width of apex of pronotum: 2.15; width of base of pronotum: 3.92; length of pronotum along midline: 1.75; length of elytra along suture: 4.50.
Body short-oval and strongly convex ( Fig. 1 View Figs 1–4. 1–2 ). Head reddish-brown. Mandibles black with reddish-brown band near apex. Maxillary palps blackish-brown. Antennomeres I–V yellowish-brown, V partially darkened, VI–XI black, XI blackish-brown apically. Pronotum reddish-brown with basal margin black ( Fig. 2 View Figs 1–4. 1–2 ). Scutellum and elytra reddish-brown. Venter reddish-brown, partially black. Legs black, partially blackish-brown.
Head. Vertex weakly convex, covered with sparse punctures, becoming coarser and denser towards sides. Frontal suture V-shaped, reaching anterior margin, coronal suture weak. Frons flat, strongly depressed at anterior margin, covered with dense punctures. Clypeus very narrow and trapezoidal. Anterior margin of labrum almost straight. Mandibles with two sharp apical teeth and large excavation for apical maxillary palpomere on outer side. Maxillary palps 4-segmented, with apical palpomere slightly widened, truncate apically.Antennae almost reaching pronotal base; antennomere I robust; II shorter than III; III longer than IV; VII–X distinctly widened, VIII–X each wider than long; XI longest, about 1.40 times as long as wide ( Fig. 6 View Figs 6–12. 6–7 ).
Pronotum. Widest at base, roundly strongly narrowed anteriorly, anterior angles strongly produced.Anterior and lateral margins bordered, lateral margins barely visible in dorsal view. Trichobothria absent on both anterior and posterior angles. Disc covered with very sparse punctures; lateral sides covered with much larger and denser punctures; interspaces covered with fine and sparse punctures. Scutellum slightly wider than long, narrowed posteriorly.
Elytra. Lateral sides slightly widened posteriorly, widest before middle, thence roundly narrowed posteriorly. Humeral calli well developed. Disc covered with eleven regular rows of large punctures, including short scutellar row; interspaces covered with fine and sparse punctures. Epipleura visible except near base in lateral view. Hind wings well developed.
Venter. Hypomera weakly rugose, with 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 slightly narrower than III. Tarsal claws appendiculate.
Genitalia. Aedeagus long and thin, very slightly narrowed apically, setose apicolaterally, with apical process rather long, apex enlarged and semicircular in dorsal view; weakly curved, apex pointed in lateral view ( Fig. 7 View Figs 6–12. 6–7 ).
Differential diagnosis. Gonioctena (B.) kuatunensis sp. nov. is very similar to G. (B.) longshengensis sp. nov., G. (B.) mauroi , and G. (B.) medvedevi in body shape, coloration and setose aedeagus, but differs in semicircular apex of aedeagus (triangular or subtriangular in other species).
Etymology. The species is named after the type locality, Kuatun [= Guadun in modern spelling] in China;.adjective
Distribution. China: Fujian ( Fig. 13 View Fig ).
