roach identification

[Birdman]

Could someone please help to identify these roaches? Bisexual reproduction, no egg case but live youngs. They came from Malaysia.

Thank you.

You mean parthenogenic, not "Bisexual reproduction".

These are common Pycnoscelus surinamensis. They are circumtropical in distribution, so are found in many countries.

All too easy to care for and a pest species in some locations.

Thank you Matt k. No, they are not parthenogenic. There are males and females involved in mating and reproduction. P surinamensis are parthenogenic and that is why I need to check if they are actually p surinamensis.

How do you know for certain there are males and females?

What about Pycnoscelus femapterus? That's a bisexual stock that's relatively circumtropical. The females of that species are wingless and the males are smaller and winged.

It looks like some of the roaches in the picture are partially winged...
