contents In this paper, we are concerned with the Hölder regularity for solutions of the nonlocal evolutionary equation $$ \partial_t u+(-Δ_p)^s u = 0. $$ Here, $(-Δ_p)^s$ is the fractional $p$-Laplacian, $0<s<1$ and $1<p<2$. We establish Hölder regularity with explicit Hölder exponents. We also include the inhomogeneous equation with a bounded inhomogeneity. In some cases, the obtained Hölder exponents are almost sharp. Our results complement the previous results for the superquadratic case when $p\geq 2$.
