We show their result for groups with $\mvir=10^{12-13}\msun$, which are most similar to MW/M31 masses.
Altogether, Figure~\ref{fig:quench_times} indicates a complex dependence of the environmental quenching timescale on satellite $\mstar$.
Specifically, the typical timescale for satellites in the MW/M31 halos increases with
satellite $\mstar$, from $\lesssim1\gyr$ at $\mstar<10^7\msun$ to $\sim5\gyr$ at $\mstar\approx10^{8.5}\msun$.
The results of
\citet{Wheeler2014} indicate
a continuation of that this
trend, mass dependence continues, though with a rapid increase ($\sim2\times$)
of the timescale to $\approx9.5\gyr$,
though interestingly they find and no change from $\mstar\approx10^{8.5}$ to $10^{9.5}\msun$.
This rapid increase
suggests implies some tension with our results, specifically,
the two satellites of M31, NGC 205 and M32 ($\mstar\approx10^{8.5}\msun$),
which are quiescent, unless
either (1) both
satellites experienced unusually early
infall, infall $>9.5\gyr$ ago, or
(2) M31
is particularly efficient at quenching quenches its
satellites, satellites particularly rapidly, even compared with
more the massive
hosts.
(\citeauthor{Wheeler2014}'s hosts in \citet{Wheeler2014}.
%(\citeauthor{Wheeler2014}'s results are consistent with the star-forming LMC/SMC of the MW.)
Finally,
the results of \citet{Wetzel2013}
indicates indicate that the quenching timescale rapidly \emph{decreases}
by $\mstar=5\times10^9\msun$ at $\mstar>5\times10^9\msun$ and continues to decline with increasing $\mstar$.
Thus, Overall, the
typical environmental quenching timescales are shortest for the lowest-mass
satellites, satellites and
the timescale is
longer longest for satellites
near with $\mstar\sim10^9\msun$ (roughly Magellanic-Cloud
masses. mass).
