Same issues here, macOS 10.13.1, MacTeX 2017 (with included TeX Live updated today using TeX Live Utility), using both XeLaTeX and LuaLaTeX.

So this sounds like an incompatibility between unicode-math (updated very recently) and lucida-otf. I can't say more, as I'm not using lucida-otf myself: I'm using direct calls to fontspec and unicode-math, based on the examples in lucidaot.tex and lucidaot-sys-example.tex from the Lucida OpenType distro.

By the way, using \textrm etc. directly in maths, that is

Compare text font faces to those in text, legacy commands:
$$\textrm{\Sphinx}   \quad   \text{{\Sphinx}}$$
$$\textsf{\Sphinx}   \quad   \text{\textsf{\Sphinx}}$$
$$\texttt{\Sphinx}    \quad   \text{\texttt{\Sphinx}}$$
$$\textbf{\Sphinx}   \quad   \text{\textbf{\Sphinx}}$$
$$\textit{\Sphinx}    \quad   \text{\itshape{\Sphinx}}$$
$$\textbf{\textit{\Sphinx}} \quad   \text{\bfseries\itshape{\Sphinx}}$$ 

does work with fontspec and unicode-math, and gives what you expected. I don't know why it works (I didn't double-check, but I think the LaTeX manuals only mention \mathrm etc. in maths), but it does.
