I don't have any input on breeding this species, but wanted to mention that according to Cifuentes et. al. (2016) Pamphobeteus petersi will be transfered to the genus Megaphobema pending a generic revision of the genus Pamphobeteus. Cifuentes et. al. (2016) states the transfer will occur due to the copulatory organ (tibial spurs) matching to that of Megaphobema.
It would be very interesting to examine these you have a Pamphobeteus petersi actually key to the genus Megaphobema. Something to think about.
