Chrysodema (Chrysodema) tonkinea Kerremans, 1909

( Figs 3F–I , 5L–T , 8D )

Chrysodema (Chrysodema) tonkinea Kerremans, 1909: 540 .

Material examined. 1 ♀ ( Fig. 3F , 5R–T ) ( CHTS): CHINA, Damingshan Nature Reserve, Nanning City , Guangxi; 11.VIII.2011; Hai-Tian Song leg. • 1 ♀ ( CHTS); Guangxi; 2009 • 2 ♀♀ ( Fig. 3G–I , 5L–Q ) ( CHTS) , 2 ♀♀ ( CCHZ); Damingshan Nature Reserve, Nanning City , Guangxi; 2006; Ying-Bing Li leg.; body ♀♀ length: 2.39–2.64 cm, width: 0.77–0.89 cm, length/width ratio: 2.97–3.10.

Distribution. China (Guangxi, new country record); Cambodia; Laos; Vietnam.

Host plant. Unknown.

Remarks. This is a variable species, which is mainly reflected in the number of transverse impressions on each elytron. Three of our four specimens only with an obvious transverse principal impression on the lateral impression towards elytral suture at apical third of each elytron. Specimens in Figs 3F and 8D have an extra transverse impression at basal third of each elytron, which angles slightly to the elytral suture. It is quite similar to Figs 138 and 139 in Lander (2003), only transverse impressions on apical third are larger. Apex of ovipositor varies, slightly protruding ( Fig. 5L ), flat ( Fig. 5O ) or slightly concave ( Fig. 5R ). Female tergite IX also changed ( Fig. 5M, P, S ) but female tergite VIII nearly constant ( Fig. 5N, Q, T ).
