Orig. Comb: Coreus calcarator Fabricius, 1803
Syn: Coreus alternatus
Say, 1825 (1)
**The following is being kept for now, but the two species (alternatus
) are considered both to be P. calcarator
Dealy (2000) gives the following diagnosis for this species:
Morphologically, P. calcarator is similar to both P. alternatus and P. indecorus, however, the body color is much paler than the latter two, often with an orange hue and all of the connexival segments of P. calcarator are unicolorous, as opposed to the bicolored segments of P. alternatus and P. indecorus. P. calcarator does not have the dark brown to black hairs covering its body that P. alternatus does.
Additionally, P. calcarator occupies only the southeast region of the United States, whereas P. alternatus and P. indecorus are more cosmopolitan across the United States and Mexico, respectively.
Baranowski and Slater (1986) concur, "Connexivum uniformly reddish brown or suffused with black, but never with alternating pale and dark markings
." But they also treat P. alternatus
as a separate sp. from P. calcarator
