What is this part called?

This is a piece that came out of an 1 1/2" ABS p-trap assembly I ordered for my shower drain. I am looking to replace just this component with one that has a slightly longer "skirt". I just need a 1" longer skirt. But al the searches for this component turn up parts that have the threads on the OUTSIDE. I need a replacement with threads on the INSIDE. There must be such an animal. Yes? What's it called please?

Looks like a FIP (female) adapter x abs male spigot.

You’d just need a FIP adapter x abs female hub and a short piece of abs.

Ya dig ?
