Diagnosis. This new species is quite differed from all congeners of the genus by having black elytra with white markings. This is also distinguished from the Taiwanese congeners by the following characteristics: 1st segments of maxillary palpi elongate; phallobase of tegmen more than half of tegmen in length; phallus well sclerotized. This species is similar to A. yichei sp. nov., but different from the latter by the following characteristics: pygidial struts curved outer apically, spicular fork with depigmented spicular lobes; fully inflated phallus nearly orthogonal to tegmen; phallobasic apodeme short, stout; phallic plate thin. This new species is also easily separable from A. yichei sp. nov., by the coloration, viz. antennomeres 3rd to 11th, surrounding parts of elytral sutures, tibiae and tarsi black; pterothoraces in ventral view yellowish orange.
Description. Male. Head, antennomeres 1st and 2nd, pronotum, femora and abdomen yellowish orange; antennomeres 3rd to 11th, apical parts of mandibles, last segments of maxillary and labial palpi, tibiae and tarsi black. Elytra black, dully shining; each elytron with two milky white markings, median transverse marking wide and reaching lateral margin and suture, then obliquely extending along suture both basally and apically, and another one other marking at apex, barely connecting to median marking via narrow sutural extension (Figs 1, 3). Head clothed with yellowish suberect setae; pronotum covered with brownish suberect setae on disk and mingled with suberect yellowish setae on marginal portion, but evenly covered with yellowish suberect setae throughout in some specimens; elytra evenly clothed with suberect black setae, mingled with yellowish setae on anterior corners; abdomen covered with suberect yellow setae (Fig. 2).
Head sparsely covered with setigerous punctures, distinctly narrower than pronotum, inserted in prothorax to the near eyes; 1st segments of maxillary palpi elongate, obliquely truncate at apex; eyes large.
Antennae serrate in antennomeres 4th–10th; antennomere 1st claviform; 2nd rounded, short, almost half length of 1st segment; 3rd elongate triangular; 4th to 10th flattened, nearly triangular, gradually becoming shorter and wider toward 10th segment; 11th flattened, broad and oval.
Pronotum convex dorsally, rounded quadrangular in shape, PW/PL 1.24–1.36 (1.30), widest at behind middle; lateral margins parallel-sided; basal and lateral margins carinate throughout; disk evenly and sparsely punctated and pubescent.
Elytra oval, EL/EW 1.15–1.30 (1.23), widest before middle, thence arcuately narrowing apically, evenly and sparsely with setigerous punctures; humeri roundly projected laterally.
Legs with femora well stout, fusiform, slightly dilated toward apical 1/5, thence slightly tapered apically; tibiae slightly and straightly dilated apically, densely covered with setae, tibial inner side setae markedly short; tibial spur formula 0-0-1.
Pygidium with posterior margin faintly emarginate at middle, pygidial struts curved outer apically (Fig. 10); 8th sternite semicircular; posterior margin almost straight (Fig. 11). Spicular fork with elongate intraspicular plate; spicular lobes depigmented and almost membranous; spicular apodeme 2/3 as long as total length of spicular fork (Fig. 12).
Aedeagus with membranous parts between well sclerotized tegmen and phallus; fully inflated phallus nearly orthogonal to tegmen (Fig. 16). Tegmen widest at basal 1/3, gently narrowed apically, weakly pointed at apex; phallobase 5/6 as long as tegmen; phallobasic apodeme short, stout, roundly expanded in ventral view, slightly and gently sinuous in lateral view (Figs 17, 18). Phallus slightly longer than tegmen, with median orifice at apex; phallic plates thin, finely spinous from subapices to before middle of phallus on ventral margins (Figs 19, 20).
Female. Similar to male, but apical margin of 7th sternite triangularly incised at middle. PW/PL 1.24–1.35 (1.29), EL/EW 1.12–1.25 (1.21).
Measurements. Male (n = 17). BL 7.6–10.8 (9.4) mm, PL 1.8–2.6 (2.3) mm, PW 2.3–3.5 (3.0) mm, EW 4.0–6.1 (5.1) mm, EL 4.9–7.3 (6.2) mm. Female (n = 8). BL 9.7–10.9 (10.2) mm, PL 2.4–2.6 (2.5) mm, PW 3.0–3.5 (3.3) mm, EW 5.3–6.0 (5.6) mm, EL 6.5–7.3 (6.8) mm.
Biological notes. Most specimens of this species were collected by sweeping flowers of Acer albopurpurascens Hayata (Aceraceae) and Fagaceae spp. along open forest road in natural forest.
Etymology. The specific name is dedicated to our Taiwanese colleague, Dr. Wen-I Chou, who kindly helped and cooperated during the collecting trip to Taiwan.
