  We study the Magnus transport in a gapped 2D electron gas with Rashba
spin-orbit coupling using semiclassical Boltzmann transport formalism. Apart
from its signature in the charge transport coefficients, the inclusion of
Magnus velocity in the spin current operator enables us to study Magnus spin
transport in the system. In particular, we study the roles of mass gap and
Fermi surface topology on the behavior of Magnus Hall and Nernst conductivities
and their spin counterparts. We find that the Magnus spin Hall conductivity
vanishes in the limit of zero gap, unlike the universal spin Hall conductivity
$\sigma_s=e/(8\pi)$. The Magnus spin currents with spin polarization
perpendicular to the applied bias (electrical/thermal) are finite while with
polarization along the bias vanishes. Each Magnus conductivity displays a
plateau as Fermi energy sweeps through the gap and has peaks (whose magnitudes
decrease with the gap) when the Fermi energy is at the gap edges.
