If I use a scientific name (Python regius) in a phrase that is already in italics, should the scientific name then be written normally or underlined? Does anybody know the rule?

2Underlined text in a hanwritten or typewriter manuscript is the equivalent to italics in typeset text. Underlines are not used in typeset text (such as books or magazines), underlines are a substitute for italics where they are not available, for example in handrwiting or on a typewriter. The exception are electronic documents, where underlines have become the standard markup for hyperlinks (for the very reason that they are not otherwise used). Never use underlining unless you are writing by hand or on an old typewriter.– user5645Commented Apr 6, 2015 at 13:09

Underlines are only used to indicate hyperlinks; they should not be used for emphasis.
When you have a block of italicized text, and you have a phrase which would normally be italicized in book or roman text, make your italic phrase book.
The ball python, also known as Python regius, is a nonvenomous python species found in Africa. This is the smallest of the African pythons and is popular in the pet trade, largely due to its typically docile temperament.
