Then after a discussion at the recent Coleopterists' Day in Oxford, Howard Mendel was kind enough to post me a couple of specimens of the new species as I had never seen one.
|Chrysomela saliceti approx 9.5mm long.|
|Chrysomela saliceti under different lighting to more clearly show the punctures on the pronotum and elytra.|
- The claw-bearing tarsal segment (two apical teeth on the underside in tremula, absent in saliceti).
- Dissection of males to check the tip of the aedeagus (equivalent of a penis).
|Tarsus ('foot') of C. saliceti - the claws are visible but no teeth on the underside.|
|The aedeagi of the two species for comparison.|
