description: Physodera bousqueti Mateu, 1990
Figs. 27, 28, 35, 55.
Mateu 1990: 156 (type locality: Berganj Lothar (Nepal); holotype in BRIO); Kabak 2003: 438; Shi et al. 2013: 41.
Material examined. China: 1 male (HBUM), " Hainan Prov. Changjiang, Bawangling, East-first station, 750m, 2008. VI.5–7, Ba Yibin & Lang Juntong leg.". 1 male (IZAS), " Hainan Prov., Qiongzhong Baihualing, D 2009.11.26, Liang Hongbin leg.". 1 female (IZAS), " Yunnan, Xishuangbanna, Menglun botany garden, Lyushilin, 2009. XI. 17, 647m, Tang Guo, Yao Zhiyuan lgt.". Vietnam: 1 male (IZAS), " Tonkin, Hoa-Binh, 1940.VIII, leg. A. de Cooman ". Malaysia: 1 female (NHML), " Malay Penin. West Coast, Langkawi Is, Apr. 21.1928.".
Diagnosis. Body length 8.5–9.0 mm. Dorsal side dark brown with purple hue and yellowish pattern. Pronotum bicolor, with brown I-shaped patch in the middle, lateral areas pale yellow, a pair of isolated dark spots present on lateral areas. Elytra with pale yellow zigzag pattern on disc. Tergum VII yellow, with one large central black spot, side area dark, forming vague side spots (Fig. 46 B). Sternum VII black, apex narrowly orange-yellow, a pair of oblique orange-yellow bands present on each side (Fig. 46 A). Pronotal hind angles distinct, about rectangular. Elytral intervals densely punctate, punctures similar with strial ones, so that the strial puncture rows difficult to distinguish; the second interval with one setigerous pore near apical fourth; the third one with one or two pores; the fifth one with one large pore near base.
P. bousqueti can be readily distinguished from all the other members of Physodera by the confused elytral punctures and zigzag pattern on elytra disc.
Male genitalia (Fig. 35). 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 very large and long, rounded apically, oviform in lateral view, its length about two times as the 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 (Fig. 55). Apical segment of ovipositor about 2.6 times long as its basal width, widest at base, gradually narrowed to apex, apex sharp; apex distinctly bent, outer margin weakly curved, inner margin strongly curved; apical half with long setae; membranous extension slender, pointed laterally.
Variation. This is a rare and relatively widely distributed species. We didn't examine the type specimen from Nepal. Compared with the habitus of type in the original literature (Mateu 1990), some specimens (Hainan, Vietnam) are slightly different in elytral patch: there is a branch of elytral patch in the third interval which is strongly extended almost reaching elytral apex in the type specimen, while this branch only shortly extended in our studied specimens.
Distribution. China (Hainan, Yunnan), Vietnam, Malaysia and Nepal. (Fig. 63)
Remarks. Two females from Yunnan and Langkawi Island (Malaya) are distinctly different from those from Hainan and Vietnam in coloration: dorsal coloration higher light; pronotum without isolated spots, which fused with the middle patch; elytral patch about quadrate, though weakly zigzag. This may be the phenomenon of sexual dimorphism.
