Hairy beetle - Macrodactylus angustatus - female

Hairy beetle - Macrodactylus angustatus - Female
Blue River Township, Harrison County, Indiana, USA
June 23, 2009
Size: 10-12 mm
Scarab of some kind perhaps. Found in woods perched on a leaf.

Moved from Macrodactylus.
Am I glad that we rescued this one from frass! A new species for the guide.

Macrodactylus angustatus female
This is the best shot I have ever seen of that species--great photo that shows the erect spine-like setae on the pronotal disc. According to Paul Lago, there apparently is some overlap in the character between subspinosus and angustatus (comparing external characters to DNA analyses), although subspinosus females generally don't have such heavy erect vestiture on the pronotum. The males simply have appressed scale-like hairs on the pronotum, not the spiked "crew cut" effect, and look fairly similar to subspinosus males dorsally.

Moved from Frass.

Moved from ID Request.

Please, don't frass yet
It is a very good image and it may be IDed to species some day. Besides we have none from Indiana.

Should I move it to genus level?

I guess so.

i agree on keeping it
I also thought it was a really nice photo.
Whatever it is, especially if different, and can be ID'd to species, will help the next person that finds it.

Macrodactylus subspinosus or related i think
Maybe it's the rose chafer, Macrodactylus subspinosus, though the thorax has different color. I could be off.
