( Figs 27 , 69–70 )

Copelatus zimmermanni Gschwendtner in Zimmermann, 1934: 143.

Type locality. “ China (Hangchow)” [ China, Zhejiang Province, Hangzhou , ca. 30°16′N 120°09′E] .

Type material. Holotype ♀, originally deposited in Yenching University , Beijing, China; destroyed during fire in 1980’.

Material examined. CHINA: Guangdong: 3 ♂, 4 ♀, Danxiashan Mts. , 23.v.2008, F. Jia leg. ( SYSU) ; 9 spec., 30 km NE Shaoguan, Duanshi vill., Danxiashan NP, 25°02.7′N 113°43.8′E, 125 m, pool, 4.-5.v.2011, J. Hájek leg. ( NMPC) ; 1 ♂, Danxiashan Mts., Yangyuanshan , 10.vi.2011, F. Jia leg. ( SYSU) .

Diagnosis. Medium sized (TL: 5.4–5.7 mm), oblong-oval species; dorsal surface distinctly convex. Head reddish, with dark band along eyes and infuscation on frons between eyes; pronotum reddish brown, laterally broadly testaceous; elytra brown, with very broad, irregularly shaped, transverse basal orange band. Pronotum with few short longitudinal strioles laterally. Each elytron with 11 superficially impressed discal striae: sutural stria usually strongly reduced to few short strioles, or almost absent in some specimens; all striae abbreviated posteriorly, striae 2, 3, 5, 7 and 9 ending in posterior fourth of elytral length, striae 4, 6, 8 and 11 reaching apical fourth of elytral length; striae 7 and 9 often fragmented to strioles throughout their length ( Fig. 27 ). Median lobe broad, club-shaped, with two protuberances on dorsal side, sinuate on ventral margin; apex beak-shaped ( Fig. 69 ). Paramere slender ‘C’-shaped; apex slender; apical lobe long, club-shaped ( Fig 70 ). Female similar to male; strioles on pronotum more numerous, elytral striae more impressed.

Collection details. The specimens from Danxiashan were collected in shallow open pool with sparse littoral vegetation, and in a pool on a stream ( Fig. 78 ).

Distribution. A species described from Zhejiang ( China), and subsequently recorded also from Japan and Korea ( Satô 1985, Park et al. 2008). First record from Guangdong province ( Fig. 83 ).
