Notes on type. According to the original literature, the syntype of P. amplicollis should be in the collection of NNML. But, Jedlička (1963) indicated that the type was destroyed. The second author of this paper did not find the type when he visited NNML. However, before finding additional evidence to support the loss of type, we are not to designate a neotype.

Diagnosis. Body length 8.8–10.0 mm. Pronotum bicolor, lateral areas yellow, not tumid, two isolated dark spots present in the yellow areas. Elytra metallic blue to violaceous, yellow patch only present at apex ( Figs. 25, 26 ). Tergum VII orange-yellow with three black spots, the central one largest ( Fig. 45 B). Sternum VII black, apex narrowly orange-yellow, a pair of oblique orange-yellow bands present on each side ( Fig. 45 A). Pronotal hind angles about rectangular. Elytral striae with distinct puncture rows, the third interval with three or four setigerous pores; the fifth with only one near base.

P. amplicollis can be readily distinguished from all the other members of Physodera , but it is similar to P. bousqueti and P. diglena by the pronotal pattern. It is different from P. bousqueti by: elytra without yellow pattern on disc; elytral striae with regular puncture rows; aedeagus less slender, apical lamella shorter (versus elytra with yellowish zigzag pattern on disc; elytral interval densely punctate, strial puncture rows indistinct; aedeagus slenderer, apical lamella longer in P. bousqueti ). Its rectangular hind angles of pronotum, the third interval of elytra with three or four setigerous pores, shorter apical lamella of aedeagus which is more sinuate before apex making it is easily separated from P. diglena (which has completely rounded hind angles of pronotum; two setigerous pores on the third interval of elytra and longer apical lamella of aedeagus which is less sinuate before apex).

Male genitalia ( Fig. 34 ). Median lobe of aedeagus gently slender, distinctly bent to right side in dorsal view, right margin strongly sinuated before apex; dorsal surface with a few fine setae subapically; apical lamella large, rounded apically, about triangular in lateral view, its length subequal to basal width. Internal sac with main flagellum not reaching the apical orifice; secondary flagellum long and distinctly sclerotized, length about 0.6 times as the main flagellum; trumpet-form expansion small, length about 0.3 times as the main flagellum; apical bursa present.

Female genitalia. Apical segment of ovipositor about 2.8 times long as its basal width, widest at base, gradually narrowed to apex, apex sharp; outer margin about straight, inner margin curved; apical half with long setae; membranous extension slender, slightly expanded at apex.

Distribution. China (Anhui, Fujian, Yunnan, Hainan, Taiwan), Vietnam, Laos, Thailand, Indonesia (Java). ( Fig. 63 )

Variation: Specimens from China ( Fig. 25 ) are slightly but distinctly different in color from those from other counties ( Fig. 26 ) in: (1) pronotum orange yellow (versus pale yellow); (2) elytra metallic dark blue (versus dark violaceous); (3) elytral apical yellow patch very narrow, patch greatest width about 1/30 as elytra full length (versus wider and forming transverse zigzag patch, patch greatest width about 1/8 as elytra full length). In some Taiwanese individuals, the pronotal black spots are close to the median patch.
