Konstantinov, Alexander S. & Duckett, Catherine N., 2005, New species of Clavicornaltica Scherer (Coleoptera: Chrysomelidae) from continental Asia, Zootaxa 1037, pp. 49-64 : 61-62

Key to Clavicornaltica species from China and Vietnam

1 Elytron very convex in lateral view [length (from apex to connection with pronotum) to width ratio 1.41 ( Fig. 5 )]. Intercoxal prosternal process high, reaching beyond procoxae. Metasternum with middle raised as high ridge ( Fig.10 ) continuing between mesocoxae ............................................................. C. longsheng new species

­ Elytron less convex in lateral view (length to width ratio 1.67 ­ 2.03) ( Figs.6­8 ). Intercoxal prosternal process low, not reaching beyond procoxae. Metasternum with middle as flat as sides ( Fig. 9 ).................................................................................... 2

2(1). Median lobe of aedeagus widening towards apex. Lateral sides of median lobe making “step” before apex, apex with acute, well defined denticle. Basal part of aedeagus longer than apical part in lateral view ( Fig.16 ) ...................... C. dali new species

­ Median lobe of aedeagus parallel sided or narrowing towards apex. Lateral sides of median lobe even, not making “step” before apex, apex with dull, poorly defined denticle. Basal part of aedeagus not longer than apical in lateral view (Figs.17,18). 3

3(2). Median lobe of aedeagus nearly parallel sided, apex asymmetrical ( Fig.17 ). Spermatheca with very short duct and pump shorter than receptacle ( Fig.19 ) ................... ................................................................................................. C. tamdao new species

­ Median lobe of aedeagus narrowing apically, apex symmetrical ( Fig.18 ). Spermatheca with very long duct and pump less than half as long as receptacle ( Fig. 23 ) ....... ......................................................................................... C. vietnamensis new species
