  In our previous work [Phys. Rev. D $\bf{101}$, 074025 (2020)], the
photoproduction $\gamma p \to K^+ \Sigma^0(1385)$ has been investigated within
an effective Lagrangian approach. There, the reaction amplitudes were
constructed by considering the $t$-channel $K$ and $K^\ast(892)$ exchanges,
$s$-channel $N$ contribution, $u$-channel $\Lambda$ exchange, generalized
contact term, and a minimum number of $s$-channel $N$ and $\Delta$ resonance
diagrams. It was found that the inclusion of one of the $N(1895){1/2}^-$,
$\Delta(1900){1/2}^-$, and $\Delta(1930){5/2}^-$ resonances is essential to
reproduce the available differential and total cross-section data for $\gamma p
\to K^+ \Sigma^0(1385)$. In the present work, we employ the same model to study
the photoproduction $\gamma n \to K^+ \Sigma^-(1385)$, with the purpose being
to understand the reaction mechanism and, in particular, to figure out which
one of the $N(1895){1/2}^-$, $\Delta(1900){1/2}^-$, and $\Delta(1930){5/2}^-$
resonances is really capable for a simultaneous description of the data for
both $K^+ \Sigma^0(1385)$ and $K^+ \Sigma^-(1385)$ photoproduction reactions.
The results show that the available data on differential and total cross
sections and photo-beam asymmetries for $\gamma n \to K^+ \Sigma^-(1385)$ can
be reproduced only with the inclusion of the $\Delta(1930){5/2}^-$ resonance
rather than the other two. The generalized contact term and the $t$-channel $K$
exchange are found to dominate the background contributions. The resonance
$\Delta(1930){5/2}^-$ provides the most important contributions in the whole
energy region considered, and it is responsible for the bump structure
exhibited in the total cross sections.
