At a glance, it looked kind of like a dipteran pupation chamber or something to that nature to me as well... But it seems to have individual chambers that might suggest an oothecae.

Blaptica dubia do produce oothecae, they are just internally incubated and rapidly dry out in the external environment. If a female is very stressed or spooked, she can potentially abort her oothecae. Don't mean to be redundant with what you were saying Eric, just wanted to clarify that a bit further. B. dubia produce litters of live offspring purely because their ooths are retained and do not become heavily scleritized like you see in some other species.
