Cryptocephalus pusillus

This was found on a Sycamore leaf. I got it to pusillus or fulvus pretty quickly and then the relatively elongate antennal segments seem to clearly point to pusillus. The length of the apical segment confirmed this, which was good as I wasn't so convinced by the femora - there is something going on at the apex which I could have happily passed off as a apicoventral flange had the other characters pointed to fulvus.

This one came to my garden moth trap. The apical segments of both antennae were 0.20mm which isn't >0.2mm as it's supposed to be but it's clearly not <0.17mm as it's should be if it were fulvus. I don't know of any differences between the spermathecae of the different Cryptocephalus species but as I'd dissected it to see if it were a male (Duff shows the aedeagi of each species) I figured I might as well have a look.
