Dyschirius sp.? - Dyschirius haemorrhoidalis

Dyschirius sp.? - Dyschirius haemorrhoidalis
Medford, (~25 miles east of Philadelphia, PA) Burlington County, New Jersey, USA
June 1, 2008
Size: ~2.7mm
Dyschirius sp.? I like the way the punctures on the elytra get weaker as the color changes from black the yellow. ID suggestions welcome :)

Moved - Thanks
Moved from Clivinini.

Thank you both. It's a lot easier to get good images when your subject doesn't move any more (especially under the bright lights :)

 
Driven by taxonomy and morphophilia,
I personally would like to see more "studio" shots like yours rather than "field" shots as emphasized by BugGuide.

yes -- may be IDable; nice pic!
a good view of the head and rear half of the elytra [to show setal pattern] may help a lot
the coarse striae vanishing behind the scutellum and far ahead of the apex are peculiar; among 38 MCZ types, only pumilus (Dejean) [as rufiventris LeC.] and perhaps brevispinus LeC. can't be excluded, i think; out of UNH-listed spp., all but larochellei (not seen) and haemorrhoidalis (here in BG) can be excluded

 
Dyschirius haemorrhoidalis
in my opinion which nicely matches my reference specimens. A species widespread in northeast. Supporting key factors are elytra with striae coarsely punctured in basal half, three pairs of so-called discal punctures (best seen in max image enlargement available only to contributing editors); smooth frons; 2.7 mm; location NJ. These images are among the best in BugGuide for desired perpendicular camera angle, clarity, brightness, and zooming capability. Without these qualities, species recognition of images become next to impossible for many tiny Dyschirius.
