Cryptocephalus alternuns jungovittatus, new subspecies described by White (1968)
The description is from two individuals taken at Monterey, California, on July 30, 1927, by D. H. Blake. [cite:212163]
Size
Length: 4.7 to 5.0 mm (2)
Identification
Elytra: Background color light orange, dark markings black, sharply delimited. (2)
Range
CA(1); there is an AZ specimen in E.G. Riley's Collection
Remarks
The external differences exhibited by this subspecies and two specimens of C. alternans alternans Suffrian from Mexico in the USNM collection are primarily a matter of coloration: the discal and lateral dark markings of the pronotum broadly join in a. alternans but join just narrowly, if at all, in a. jungovittatus
