  A light singlino is a promising candidate for dark matter, and a light
higgsino is natural in the parameter space of the NMSSM. We study the combined
constraints on this scenario resulting from the dark matter relic density, the
most recent results from direct detection experiments, LEP and the LHC. In
particular limits from a recent search for electroweak production of charginos
and neutralinos at $\sqrt{s}=13$ TeV after 35.9 fb$^{-1}$ by CMS and
constraints on spin-independent dark matter-nucleon cross sections from XENON1T
after one tonne$\times$year exposure are considered. We find that scenarios
with higgsino masses below $\sim 250$ GeV as well as singlino masses below
$\sim 100$ GeV are strongly constrained depending, however, on assumptions on
the bino mass parameter $M_1$. Benchmark points and branching fractions for
future searches at the LHC are proposed.
