Abstract

We proved (Pacific J. Math. 293:1 (2018), 101–120) that if $L$ is a contact stationary Legendrian surface in ${\mathbb{𝕊}}^{5}$ with the canonical Sasakian structure and the square length of its second fundamental form belongs to $\left[0,2\right]$, then $L$ is either totally umbilical or is a flat minimal Legendrian torus. In this addendum we further prove that if $L$ is a totally umbilical contact stationary Legendrian surface in ${\mathbb{𝕊}}^{5}$, then $L$ is totally geodesic.
