4-spotted hairy fungus beetle - Litargus tetraspilotus

4-spotted hairy fungus beetle - Litargus tetraspilotus
Nashua, Hillsborough County, New Hampshire, USA
July 20, 2005
Size: 2.3 mm
Came to UV lights. Can anyone recognize the species by outline and elytral markings?

Mycetophagidae: Litargus tetraspilotus
Litargus tetraspilotus rings a bell.

 
Shape looks right.
Spots are a little different on the one Web image I've located.

Looks like another new family for bugguide!

 
Litargus placement
Yes, the spots are a bit redder than normal. The posterior spots are curving posterolaterally on your image, but are not easy to see, and so they look smaller. I actually looked at the specimens in the collection for this one, and it does fall within the range of variation, and there are no other candidates of which I am aware.

 
Excellent
And thank you for checking it against the collection.
