Hi wm in arizona,
This is a Cockroach, and we believe it is the Surinam Cockroach, Pycnoscelus surinamensis, even though BugGuide does not report the species from Arizona.  It is reported in Texas and Florida as well as other southern states.  According to BugGuide, the Surinam Cockroach:  “Reproduces through parthenogenesis in the US, where no males are found. It has two sexes in some parts of the world (Europe and Indo-Malaysia), though. Unlike many roaches, the egg capsule is retained inside the female’s abdomen until young are ready to emerge. Usually described as giving birth to live young, however Modern Pest Services site below seems to show that the egg capsule is ejected from the female.“
