thank you

Thank you!
I knew I had seen this species and I ranked quickly but without confirmation. I have a little trouble making my eyes with this group.

I have two specimens of H. hemipodius collection and I think it does not look like himself. http://bugguide.net/node/view/866122

One is 10 mm and the other 15 mm. Moreover, the shape of the pronotum seems different. One is convex and the other relatively straight.Is this a diphormisme(male vs. female)?

yeah thinking sexual dimorphism

females of many clickers will often have wider pronota with less dense punctures; the degree of difference seen varies within a species so one cannot say that all females of a given species will look this radically different.
Also females do tend to be both longer and broader/huskier than males.

Hemicrepidius hemipodus is highly variable with regards to color as well; from all black to black with all-orange elytra (as seen here). Legs can be pale or dark.
