1E6FA5333D4450B282C01DE5C5B9AB4E.taxon	diagnosis	Diagnosis. Adults of Argopistes biplagiatus are similar to those of A. rufus with similar color pattern but differing from A. rufus possessing line of punctures that are less coarse than those between the lines, sometimes confused (lines of punctures much coarser than those between lines in A. rufus) and a wider interspace between eyes. Genitalic characters are more diagnostic for both species. Those of A. biplagiatus possess pointed apices (Fig. 3 C) and are wider in lateral view (Fig. 3 D) (widely rounded apex (Fig. 5 C) and narrow aedeagus in lateral view (Fig. 6 D) in A. rufus); females have narrow, parallel-sided bases of gonocoxae (Fig. 3 G) (medially widened gonocoxae (Fig. 5 G) in A. rufus), and ventrite VIII evenly rounded and with dense setae on apical margin (Fig. 4 E) (medially depressed and without setae on median area of apical margin of abdominal ventrite VIII (Fig. 5 E) in A. rufus). In addition, adults of A. biplagiatus in Taiwan are larger (4.7 – 4.9 mm) than those of A. rufus (3.8 – 4.3 mm). Moreover, distinct color patterns occur in both species respectively (black elytra with reddish brown at middle in A. biplagiatus; yellowish brown elytra with distinct arrangement of black spots in A. rufus).	en	Lee, Chi-Feng, Chiang, Ming-Yao, Suenaga, Haruki (2024): The genus Argopistes Motschulsky from Japan and Taiwan, with descriptions of three new species from Taiwan (Coleoptera, Chrysomelidae, Galerucinae, Alticini).

In addition, adults of A. rufus in Taiwan are smaller (3.8 – 4.3 mm) than those of A. biplagiatus (4.7 – 4.9 mm).
