Diagnosis

Dercetina taiwana is similar to Dercetina chinensis and Dercetina barclayi sp. n. in the absence of lateral fovea on the pronotum and antennomere III slightly longer than IV. Dercetina taiwana and Dercetina chinensis are separated from Dercetina barclayi sp. n. by its sexually dimorphic antennae. Both species have their distinct color patterns in most individuals: the bluish black elytra with white transverse band at middle in Dercetina taiwana; the yellowish brown elytra with or without longitudinal black bands long suture and lateral margins in Dercetina chinensis. Although some individual specimens of both species share the same color pattern, Dercetina taiwana differs from Dercetina chinensis by a more oval elytra (1.4 times longer than wide in contrast with 1.6 times longer than wide in Dercetina chinensis).

Redescription

Color (Figs 46–47) bluish black, head (except eyes and antennae), prothorax, coxae, and tibiae yellowish brown; elytra with one transverse white stripe at basal 1/3. Head smooth and impunctate. Pronotum transverse, 1.9–2.0 times wider than long, evenly convex on disc and lacking fovea or punctured depression, disc with scattered fine punctures; lateral margin rounded, anterior margin concave, posterior margin slightly rounded. Elytra more or less widened posteriorly, apex convergently rounded, 1.4 times longer than wide, disc with punctures in part arranged in longitudinal rows, epipleurae smooth and impunctate.
Male. Length 4.0–4.5 mm, width 2.2–2.5 mm. Ratio of length of antennomeres III to XI about 1.0: 1.3: 1.3: 1.3: 1.3: 1.2: 1.2: 1.1: 1.3; ratio of length to width of antennomeres III to XI about 2.5: 2.9: 3.0: 3.2: 3.3: 3.3: 3.6: 3.6: 4.5 (Fig. 56). Penis (Fig. 58) extremely slender, about 8.4 times longer than wide, parallel-sided, basally widened, apex narrowly rounded; tectum membranous, with scatted stout setae; weakly curved in lateral view (Fig. 59); endophallic sclerite elongate, about 0.4 times as long as penis, base and apex concave and membranous, with a dorsal sclerite connected at basal 1/4, almost reaching base, with a row of short setae along lateral margin at apical 1/4; in lateral view almost straight. Female. Length 5.2–5.7 mm, width 3.0–3.3 mm. Antenna 11-segmented, filiform (Fig. 57), comparatively narrower than in male, ratio of length of antennomeres III to XI about 1.0: 1.3: 1.3: 1.3: 1.3: 1.3: 1.3: 1.2: 1.5; ratio of length to width of antennomeres III to XI about 2.9: 3.1: 3.3: 3.5: 3.6: 3.5: 3.9: 4.0: 5.4. Sternite VIII (Fig. 60) weakly sclerotized subapically, apex truncate, setae along lateral and apical margin, spiculum long. Spermathecal receptaculum (Fig. 61) swollen; pump narrow and strongly curved, apex narrowly rounded; spermathecal duct short, deeply projecting into receptaculum. Gonocoxae (Fig. 62) narrowly connected in middle, about 4.6 times longer than wide, straight, with one short setae at apical 1/3 and nine setae at apex.
Color variation. A number of individuals have transverse white strip on elytra reduced at various degrees, or even totally absent (Fig. 48); some have the vertex, clypeus, and labrum darkened; a few individuals have pronotum darkened.
