At or near Calleida punctulata Chaudoir.
At or near Calleida punctulata Chaudoir. If true, the Arizona specimens would represent a new state record. This one is conspecific with other Arizona examples posted on BugGuide. As Jonathan Quist pointed out at the post-2012 Caraboidea Registry, the AZ individuals appear superficially different from posted Texas examples of "C. punctulata". My concept of this species is derived from the descriptive account of "Callida rugicollis Horn, 1894:361". The latter was deemed a synonym of C. punctulata Chaudoir by Schaeffer (1910:396). In my early comparative analysis, the Horn account appears to better fit the photographed TX examples although I did not physically examine them. Specifically, the TX images fit the expected proportionately wider pronotum, pronotal sides only feebly sinuate, elytral intervals more prominently punctate. According to Horn, the third elytral interval has "four dorsal punctures". The AZ examples have only two and I can't see the number in the TX images. Help on the numbers from my Texas colleagues would be greatly appreciated. Not mentioned by Horn are a pair of faint reddish spots on head (occiput) that I see in the AZ examples but unfortunately are not visible in the BugGuide images. For now I'll keep AZ records with "C. punctulata" along with this taxonomic note. There are three likely outcomes: (1) AZ and TX populations are conspecific with regional variation in pronotum; (2) they are allospecific with one population a described Mexican species; (3) One is true "C. punctulata", the other an undescribed species.
