Drunella coloradensis / flavilinea - voucher specimens in alcohol - Drunella
Healdsburg, Russian River, Sonoma County, California, USA
April 3, 2013
Size: 9-11 mm
I've included a large number of pictures of this species because there are several color variants. I used Allen and Edmunds' key for Drunella (1962) to determine the species but once it got down to a choice of D. coloradensis and D. flavilinea I couldn't narrow it down any further.
