Blapylis planata (Eschscholtz, 1829)
Blapylis novoverrucula (Boddy, 1957)
Blapylis scabrosa (Eschscholtz, 1829)
Genus: Blapylis Horn, 1870 (Eleodes (Blapylis))
Type species: Eleodes cordata
Range: Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, Wyoming (USA), Alberta, British Columbia (CAN), and Baja California (MEX)

-The following is a list of species within Blapylis-
The cordata Group:
the most easily separated group within Blapylis, best characterized externally by their usually angulately arcuate pronotum and deep pronotal punctures
Binomial: Blapylis cordata (Eschscholtz, 1829) (Eleodes cordata)
Range: Northern California
Size: Usually more than 12mm

My Remarks: This appears to be the most common species of Blapylis in California above Thousand Oaks. In most of its range it cannot be confused for any other Blapylis species except tuberculata, which it is separated from by its larger size (usually over 12mm) and proportionally smaller elytral tubercules. In the northeastern part of its range it overlaps with hybrida, brunnipes, pimeliodes, and nuenmacheri. It should be mentioned that spilmani of the caseyi group looks quite similar to this species.
Binomial: Blapylis tuberculata (Eschscholtz, 1829) (Eleodes tuberculata)
Range: Coastal California
Size: Usually less than 12mm

My Remarks: Blapylis tuberculata is apparently most common around the coastal areas of the San Fransico Bay, it is found north to Manchester and supposedly ranges as far south as San Diego, although records become sparse past Monterey. Its range should only overlap with that of cordata and is separated from it by its smaller size (usually less than 12mm) and proportionally larger elytral tubercules. A record of pimeliodes exists from the Bay Area, which (if accurate) should not present a problem in distinguishing these two species by the elytral tubercule size proportional to the rest of the body.
