Remove space between figure label and number in caption within a separate floating environment

Question

I created a separate floating environment for my supplementary figures using \usepackage{newfloat} \DeclareFloatingEnvironment[name={Figure S}]{suppfigure}.

However, this prints in the figure caption "Figure S 1" with a space between S and the number. How can I remove this space only for this floating environment?

(I know about \renewcommand{\thefigure}{S\arabic{table}}, however this works globally and since I also have normal figure environments this is not possible.)

MWE:

\documentclass[a4paper]{scrbook}
\usepackage[utf8]{inputenc}

\usepackage{newfloat} \DeclareFloatingEnvironment[name={Figure S}]{suppfigure}

\begin{document}
\begin{suppfigure}
    \centering
    \caption{Test}
\end{suppfigure}

\end{document}

Answer 1

The suppfigure environment has its own counter.

\documentclass[a4paper]{scrbook}
\usepackage{newfloat}

\DeclareFloatingEnvironment[name={Figure}]{suppfigure}
\renewcommand{\thesuppfigure}{S\arabic{suppfigure}}

\begin{document}
\begin{suppfigure}
    \centering
    \caption{Test}
\end{suppfigure}

\end{document}

Answer 2

One approach would be to add some negative horizontal space at the end of the name-attribute, like so:

\documentclass[a4paper]{scrbook}
\usepackage[utf8]{inputenc}

\usepackage{newfloat} \DeclareFloatingEnvironment[name={Figure S\hspace{-.6ex}}]{suppfigure}

\begin{document}
\begin{suppfigure}
    \centering
    \caption{Test}
\end{suppfigure}

\end{document}

You can fine tune the space to your liking.
