Figs. 21 , 31 , 41 .

Darlington 1971: 326 (type locality: Finisterre Range (New Guinea); holotype in NHML); Shi et al. 2013: 41.

Material examined. Holotype of Physodera bacchusi Darlington ( NHML), a male, " Holo / type " [round label with red circle]; "Stn. No. / 30"; "New Guinea: / Madang Dist. , / Finisterre Mts. / Damanti 3,550 ft . / 2–11.x.1964 "; "M.E.Bacchus. / B.M. 1965-120"; " Drawn 1968 / M.Catron / No.498 "; " Drawn 1968 / M.Catron / No.483 "; " Holotype / Physodera / bacchusi / Darl." [red label] ( Figs. 9 , 21 ); 3 males ( CCCC) " Xizang auto region., Mêdog county , near the township, 1100m, on tree trunk; Yang Xiaodong lgt., 2012. VII.30. "

Diagnosis. Body length 11.0– 11.5mm; body form weakly convex. Head and pronotum dark brown, pronotum without pattern; elytra dark green, with distinct metallic hue, and a pair of small red spots near apex: spots about one seventh as the elytra in length, occupying intervals 2–4 in width, spots not conjoint at elytral suture. Tergum and sternum VII dark, without distinct pattern, a little yellowish around spiracles. Pronotal hind angles sharp, about rectangular; setae only present near front and hind angels. Elytral third interval with three very small setigerous pores; the fifth with four or five small pores near base; the seventh interval with a series of fine setae. Comparisons with related species see diagnosis under P. andrewesi .

Male genitalia ( Fig. 41 ). Median lobe of aedeagus gently slender, apex strongly bent to right side in ventral view, right margin sinuated before apex; apical lamella small, its length about equal to the basal width, about triangular, rounded apically. Internal sac with main flagellum fine and curved, apex reaching apical orifice; secondary flagellum weakly sclerotized, length about 0.4 times as the main flagellum; trumpet-form expansion small, length about 0.3 times as the main flagellum; apical bursa absent. Female genitalia unknown.

Distribution. New Guinea and China (Xizang). ( Fig. 66 )

Remarks. It is unexpected to find this species in south Xizang, where is very far from the only know locality, New Guinea. The identical external and male genital characters between specimens from the two localities ( Figs. 21 , 31 ) educed that this rare species has a very wide range. Further explorations are expected to fill the distribution gaps in southeast Asia.
