Little Black Beetle with Orange - Glischrochilus fasciatus

Little Black Beetle with Orange - Glischrochilus fasciatus
Cambridge, Middlesex County, Massachusetts, USA
April 27, 2006
Size: ~4mm
In the lid of a compost bin. Note the tiny mite next to it. I'm curious about the two light bumps on the side of the thorax(?).

Mites?
Does anyone know if those are mites (two on the right side and one near the left eye)?

Nitidulidae: Glischrocheilus fasciatus
This is the same species that others have identified as Glischrocheilus fasciatus.

 
Glischrochilus fasciatus
Thanks for the ID, Donald. 4-7 mm sounds like the right size.

Nicrophorus sp.
I believe this is a Sexton Beetle, genus Nicrophorus. There are a number of species, but most have this sort of orange marking on a black background, and shorter elytra that leave the posterior of the abdomen exposed. Like other Silphidae, they have a ball-shaped apex of the antennae.

dont think its a silphid
looks a little like one the pleasing fungus beetle family Erotylidae they range from 3-20mm so it could be something in this family. but it doesnt look like any siphid I have worked with

 
Too small?
Nicrophorus looks plausible except for the size -- the Info page says 16-35 mm, but this one was much smaller than that.

 
You're right, too small
Ooops, I failed to note the size of your beetle. You're right, way too small for any Nicrophorus I've ever seen.

This color scheme always makes me think of a Pleasing Fungus Beetle genus, Megalodacne, but among other differences Megalodacne is also too large to match your beetle.

Well I will keep looking and maybe someone else will chime in with some thoughts here too.
