Rhysida longipes longevity after maturing?

[Arthroverts]

Hello everyone, my local invertebrate store (I'm serious, they have more invertebrates than reptiles) recently got in a Rhysida longipes (African long tail centipede). Its about three inches long (which is about their max size), which leads me to the question, how long do they live after maturing? Any help is greatly appreciated.
Thanks
