Gonioctena (Gonioctena) fujiana Cho & Borowiec sp. nov.
( Figs 19–20 View FIGURES 19 – 24 , 48–49 View FIGURES 48 – 53 )
Types. Holotype: male (NMPC), Cina, Fukien, Kuatun, V.1946, leg. Tschung-Sen // HOLOTYPUS Gonioctena (s. str.) fujiana sp. n. Cho & Borowiec 2014. Paratypes: 2 males (LMCM, TLMF), same data as holotype.
Diagnosis. Gonioctena (Gonioctena) fujiana sp. nov. is closely related to G. (G.) kamikawai and G. (G.) kanfani in having elytral humeri with a black spot surrounded by yellowish brown circle, elytra with partially double striae and aedeagus with flagellum divided into 3 parts at apex. These characters are unique in the subgenus Gonioctena . However, Gonioctena fujiana sp. nov. can be distinguished by body length 7.80–7.85 mm (5.90–6.40 mm in G. kamikawai and 7.10–8.80 mm in G. kanfani ) and apex of aedeagus wider than median lobe (wider than half width of median lobe in G. kamikawai , Fig. 50 View FIGURES 48 – 53 , and much narrower than half width of median lobe in G. kanfani ).
Description. Measurements in mm (n = 2): length of body: 7.80–7.85 (mean 7.83); width of body: 4.90–4.95 (mean 4.93); height of body: 3.10–3.15 (mean 3.13); width of head: 2.10–2.12 (mean 2.11); interocular distance: 1.45 (mean 1.45); width of apex of pronotum: 2.45–2.47 (mean 2.46); width of base of pronotum: 3.85–3.87 (mean 3.86); maximum width of pronotum: 3.92 (mean 3.92); length of pronotum along midline: 1.90 (mean 1.90); length of elytra along suture: 5.90–5.95 (mean 5.93).
Body oblong oval and moderately convex ( Fig. 19 View FIGURES 19 – 24 ). Head dark reddish brown, with 2 black spots on vertex, apex of mandibles black. Antennomeres 1–7 reddish brown, 7 partially darkened, 8–11 blackish brown. Pronotum dark reddish brown, with 9 black spots. Scutellum copper brown, basal margin black. Elytra copper brown, with feeble cupreous metallic reflections, except humeri yellowish brown with a pair of black spots. Venter largely dark reddish brown, partially darkened. Legs entirely reddish brown.
Head. Vertex weakly convex, covered with dense punctures. Frontal suture V-shaped, coronal suture weak. Frons flat, strongly depressed at anterior margin, covered with dense punctures. Clypeus very narrow and trapezoidal. Anterior margin of labrum weakly concave. Mandibles with 2 sharp apical teeth, a large excavation for maxillary palp at outer side. Maxillary palp 4-segmented, with apical palpomere distinctly widened, truncate apically. Antennae reaching base of pronotum; antennomere 1 robust, longest; antennomere 2 shorter than 3; antennomere 3 longer than 4; antennomeres 7–10 widened, 7–9 each longer than wide, 10 almost as long as wide; antennomere 11 about 1.44 times as long as wide ( Fig. 48 View FIGURES 48 – 53 ).
Pronotum. Lateral sides widest near base, roundly narrowed anteriorly, anterior angles strongly produced ( Fig. 20 View FIGURES 19 – 24 ). Anterior and lateral margins bordered, lateral margins well visible in dorsal view. Trichobothria present on posterior angles. Disc covered with sparse or dense punctures; lateral sides covered with much larger and denser punctures; interspaces covered with fine and sparse punctures. Scutellum slightly wider than long, roundly narrowed posteriorly.
Elytra. Lateral sides moderately widened posteriorly, widest beyond middle, thence roundly narrowed posteriorly. Humeral calli well developed. Disc covered with rather irregular punctures arranged in confused single or double 11 rows, including a short scutellar row; interspaces covered with fine and sparse punctures. Epipleura visible except apical 2/ 5 in lateral view. Hind wing well developed.
Venter. Hypomera rugose, with coarse punctures on anterior 1/4. Prosternum covered with coarse and dense punctures bearing long setae; prosternal process enlarged apically, bordered laterally, with sparse punctures. Metasternum covered with minute 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 a tooth-like projection. Fore legs with tarsomere 1 slightly narrower than 3. Tarsal claws appendiculate.
Genitalia. Aedeagus long and thin, subparallel-sided, slightly widened before apex, apex widely rounded in dorsal view; moderately curved, apex pointed in lateral view; apex of flagellum divided into 3 parts ( Fig. 49 View FIGURES 48 – 53 ).
Etymology. Named after the type locality, Fujian Province [= Fukien in formerly romanised form].
Distribution. China (Fujian).
