Aims. The accretion-powered pulsar 4U 1626-67 experienced a new torquereversal at the beginning of 2008, after about 18 years of steadily spinningdown. The main goal of the present work is to study this recent torque reversalthat occurred in 2008 February.  Methods. We present a spectral analysis of this source using two pointedobservations performed by Suzaku in 2006 March and in 2010 September.  Results. We confirm with Suzaku the presence of a strong emission-linecomplex centered on 1 keV, with the strongest line being the hydrogen-like NeLy-alpha at 1.025(3) keV. We were able to resolve this complex with up to sevenemission lines. A dramatic increase of the intensity of the Ne Ly-alpha lineafter the 2008 torque reversal occurred, with the equivalent width of this linereaching almost the same value measured by ASCA in 1993. We also report on thedetection of a cyclotron line feature centered at ~37 keV. In spite of the factthat an increase of the X-ray luminosity (0.5-100 keV) of a factor of ~2.8occurred between these two observations, no significant change in the energy ofthe cyclotron line feature was observed. However, the intensity of the ~1 keVline complex increased by an overall factor of ~8.  Conclusions. Our results favor a scenario in which the neutron star in 4U1626-67 accretes material from a geometrically thin disk during both thespin-up and spin-down phases.
