We report on analysis of the poorly studied source 2RXP J130159.6-635806 at different epochs with ASCA, BeppoSAX, XMM-Newton and INTEGRAL. The source shows coherent X-ray pulsations at a period ${\sim}700$ s with $\dot{\nu}\sim 2\times 10^{-13}$ Hz s$^{-1}$. A broad band (1–60 keV) spectral analysis of 2RXP J130159.6-635806 based on almost simultaneous XMM-Newton and INTEGRAL data demonstrates that the source spectrum is an absorbed power law with a photon index $\Gamma\sim 0.5-1.0$ and a cut-off energy of ${\sim}25$ keV. We also report on the identification of the likely infrared counterpart to 2RXP J130159.6-635806. The interstellar reddening does not allow us to strongly constrain the spectral type of the counterpart. The latter is, however, consistent with a Be star, the kind of which is often observed in accretion powered X-ray pulsars.
