Thanks for asking!
Based on my location and the appearance from above, I figured it had to be either E. tristigmus or E. servus. E. tristigmus tends to be much darker dorsally (but not always). Almost all (but not all) of the E. servus photos show green or yellow ventrally, and almost all (but not all) of the E. tristigmus photos show tan ventrally, like this fellow. There's no info on the info page for E. servus about the appearance ventrally for that species, but the info page for for E. tristigmus says "Abdomen ventrally with 1-4 black spots down midline (spots obsolete in some individuals)", so I figured that this fellow either had "obsolete" spots or that what spots he does have are hidden by the stick in the photo. I looked at how rounded/pointed the shoulder spines are, but there's a LOT of variation there. I looked at the length of the "nose", and it seems that E. servus has a longer "nose" than E. tristigmus. So, with his dark dorsal surface, tan ventral surface, and short "nose", I figured it had to be E. tristigmus. Add in the dark antenna tips, and I concluded E. tristigmus luridus. I'd be delighted to know what you think - again, thanks for asking! :)
