C. longulus
ssp. lenticus; keyed from Larson et al (2001)...recognized by broad metasternal wing (0.35 mm or greater at narrowest point between mesocoxa and edge of metacoxal plate)..since actual length was provided, was able to figure out magnification of the specimen.

 
Excellent!
Much thanks, Tim.
