Treatment

Aradus chinensis VÁSÁRHELYI 1988 ( figs 11-21 View Figs 11-21 )

Due to lack of comparative material, the westpalaearctic Aradus betulae (LINNAEUS 1758) was reported to occur in China ( HSIAO 1964, LIU 1981). VÁSÁRHELYI recognized it as a new taxon and described it on specimens from Tianjin as the new species A. chinensis . He compared it with the eastpalaearctic A. hieroglyphicus J. SAHLBERG 1878, stating that A. chinensis shows small differences in the length of antennae, particularly of segment II and in the male genitalic structures.

Investigation of comparative material now available of " A. chinensis " from China, Sichuan (Alshu-Nanping, Juizhaigou 8-13 VI 1991, lg. Holzschuh & Li (CEHI) and further specimens of A. hieroglyphicus from Ussuri and Primorsky Kraj compared with paratypes of A. chinensis has shown, that the male genitalic structures, important characters for species taxonomy of Aradus , are identical within some smaller variability ( figs 11-17 View Figs 11-21 ). The length of antennae and that of segment II is variable and specimens from Sichuan show no differences to those from Russia ( figs 18-21 View Figs 11-21 ).

Therefore a new synonymy is proposed: Aradus hieroglyphicus J. SAHLBERG 1878 = Aradus chinensis VÁSÁRHELYI 1988 nov.syn.
