Glyphonyx knulli

Glyphonyx knulli
Hank&Yanks Springs on Ruby Road, Santa Cruz County, Arizona, USA
July 24, 2004
Size: 4.5 mm
I'm pretty confident on this ID; although it gave me some fits. Keys out well in Smith & Blasbaugh (1984) based on:

-frontal and nasale carinae joined at the middle
-prosternal process margined to apex
-size and color
-length of elytra only slightly more than twice the width
-lateral pronotal carina extending to almost, but not beyond, 3/4 length of pronotum (1/2 to 2/3 length)
-geographic distribution (the type is from southern AZ in the Catalina Mountains)

another new one, 6 more to go?
