Histronica and rostrata often have that ladder-effect of vertical bars connected by a short horizontal bar.
Kuobtai almost never do, but are more of a spotted pattern. Look into them, anyway.
Kubs definitely change their pattern as they grow, so might at some point (as a juvenile especially) look sort of like that. If you have had yours a while (several months at least) you may have seen them change their pattern. Its worth a look.
Here is a link to the kubotai, and within that are links to the other 2.
Look at several pictures of all these so you get a better feel for what they look like, as they all are somewhat variable.
