Leaf Beetle - Luperosoma subsulcatum - Male
East of Rio Rico, Santa Cruz County, Arizona, USA
August 8, 2009
Size: 3.9 mm

Det. E. G. Riley. This is a male as determined by the weakly enlarged terminal antennomeres and the small subapical notch on the inner margin of the mesotibia.

Thank you and Dr Riley
very much for your help!

Moved from ID Request.

Reminds me...
of this except that it looks like the first couple of segments of antennae are a little different...

This one also has hooked tarsals... Oh well, it's interesting to see how similar beetles from totally different taxonomies can look...
