Sorry, it's not a Phylus...

The body shape, particularly the pronotum shape is very different from Phylus. The lateral margin of the pronotum of this bug is somewhat rounded, while that of Phylus is almost rectilinear. Furthermore, the ratio of length to width of the pronotum is very different between two species.

So, my previous ID was wrong.

Instead, i believe now it is a Plagiognathus species, in particular, P. longirostris. According to Schuh, P. longirostris is recognized by "nearly black, elongate body (fig. 9), entirely pale white legs (fig. 9), pale antennae with segment 1 dark only at extreme base (fig. 17)," etc.

The linked paper gives a key to Plagiognathus species, photos of all species, and schematic figures of antennae as well as the description of species, so you may confirm my new suggestion.

Your photo is so excellent that i can easily ID it.

Schuh's key is faulty for this species

You have to watch out when using his key for P. modestus vs P. longirostris. Weirdly, the key in Schuh (p. 21, couplet 4b) mentions P. longirostris having an entirely pale first antennal segment, but his diagram of the antennae on p. 109, photo on p. 101 and descriptions on pp. 16 and 155 all show and mention the dark base. This confused me considerably! I've no doubt this is mentioned in a later issue of the AMNHB as an erratum, but of course it isn't in the pdf copy of the original publication.

It's better to have a time...

It's somewhat different from Phylus...

looks like Phylus

It may be Phylus coryli...

And, Phylus coryli is a single species in the Genus Phylus that live in North America.

Thanks for the ID, WonGun.
