Diagnosis. This species is very similar to A. choui sp. nov. in the general appearances, but easily distinguishable from the latter by the following characteristics: pygidial struts straight apically, spicular fork lacking spicular lobes; fully inflated phallus forming an acute angle towards tegmen; phallobasic apodeme elongate; phallic plate thicker. It is also easily separable from those of A. choui sp. nov. by coloration, viz. antennae and legs entirely yellowish orange, pterothoracies brownish black, and surrounding parts of elytral suture milky white.
Description. Male. Head, antennae, pronotum, legs and abdomen yellowish orange; scutellum brownish yellow; apical parts of mandibles, venter of pterothorax brownish black. Elytra dully shining black except for suture and white bands on middle and apices, with two transverse milky white bands at middle and at apex, middle band usually forming transverse wide band that obliquely extends along suture and lateral ridge of elytra (Figs 4, 6), but in some specimens reduced to small spots transversally arranged near elytral middle (Figs 7–9); suture milky white. Head clothed with yellowish suberect setae; pronotum with yellowish suberect setae on disc and mingled with brownish suberect setae on marginal part; elytra evenly clothed with suberect black setae, mingled with yellowish setae on anterior angles; abdomen covered with suberect yellow setae.
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 gently serrate in antennomeres 4th–10th; antennomere 1st claviform; 2nd rounded, short, almost half length of 1st; 3rd elongate triangular; 4th to 10th flattened, almost triangular, gradually becoming shorter and wider toward 10th; 11th flattened, broad and oval.
Pronotum convex dorsally, rounded quadrangular in shape, PW/PL 1.25–1.47 (1.34), widest at basal 1/3; lateral sides slightly dilated basally; basal and lateral margins carinate; disk evenly and sparsely vested with setigerous punctations throughout.
Elytra oval, EL/EW 1.16–1.31 (1.23), widest at middle thence arcuately narrowed apically, evenly and sparsely punctured and pubescent; humeri roundly projected laterally.
Legs with femora stout, fusiform, slightly dilated toward apical 1/5, thence slightly tapered apically; tibiae slightly and linearly dilated apically, densely covered with setae which are markedly short on inner sides; tibial spur formula 0-0-1.
Pygidium with posterior margin nearly straight but slightly emarginate at middle, pygidial struts straight apically (Fig. 13). Eighth sternite trapezoidal; posterior margin almost straight (Fig. 14). Spicular fork with an elongate intraspicular plate, lacking spicular plates; spicular apodeme 3/4 as long as the total length of spicular fork (Fig. 15).
Aedeagus with membranous parts between sclerotized tegmen and phallus; when fully inflated, the phallus is forming an acute angle towards tegmen (Fig. 21). Tegmen widest before middle in ventral view; phallobase 3/4 as long as tegmen, gently narrowed apically, weakly pointed at apex; phallobasic apodeme dilated near base in ventral view, almost flattened in lateral view (Figs 22, 23). Phallus equal in length to tegmen, with median orifice at apex; phallic plates thick, finely spinous from subapices to the middle of phallus on ventral margins (Figs 24, 25).
Female. Similar to male, but apical margin of 7th sternite triangularly incised at middle. PW/PL 1.19–1.35 (1.30), EL/EW 1.07–1.39 (1.21).
Measurements. Male (n = 19). BL 6.2–8.4 (7.5) mm, PL 1.4–2.0 (1.7) mm, PW 1.8–2.7 (2.3) mm, EW 3.3–4.6 (4.1) mm, EL 4.0–5.7 (5.1) mm. Female (n = 19). BL 6.7–8.8 (7.9) mm, PL 1.7–2.1 (1.9) mm, PW 2.1–2.7 (2.5) mm, EW 3.6–5.1 (4.4) mm, EL 4.5–6.0 (5.3) mm.
Biological notes. Most specimens were collected by sweeping flowers of Acer albopurpurascens Hayata (Aceraceae), Lithocarpus kawakamii (Hayata) Hayata (Fagaceae) and Fagaceae spp. This species is sometimes collected together with A. choui sp. nov.
Etymology. The specific name is dedicated to our Taiwanese colleague, Mr. Yi-Che Hsu.
