I had been looking for some sort of definitive listing of all the known species of Eupholus weevils for quite a while and finally found this book. It looks incredibly thorough, has both English and French text, and was written by a couple of folks that are credited with describing dozens of species in the genus. I ordered a copy and it should be here sometime in the next week or so. I'll provide an update/review when I get a chance to read through it.
I received it in the mail the other day, but it's a birthday gift so I haven't been able to read it yet. I still have a couple weeks to wait. I did open the package and the book is big (12 inch by 9 inch / 295x240mm) and heavy (over 3 lbs / 1.5kg). Definitely a bigger book than I was expecting.
Finally got a chance to look through it, and it's incredible. It's a big heavy book full of hundreds of photos representing all the different species. For example, the entry for E. geoffroyii has 34 different images showing the wide variability that can be seen in this species. I was really impressed with the E. bennettii entry that has 64 different examples. I had no idea there was that much variation in a single species. The smallest photos are about 2 to 2.5 times life size and many are larger than that so you can really see the details in the scale structure. For some of the rarest species there may only be a single photograph, but it really helped clarify a lot of the issues I was having identifying specimens.
