  Employing {\it state of the art} high resolution photoemission spectroscopy,
we studied the temperature evolution of the electronic structure of
EuFe$_2$As$_2$, an unique pnictide, where antiferromagnetism of Eu layer
survives within the superconducting phase due to `FeAs' layers achieved via
substitution and/or pressure. High energy and angle resolution helped to reveal
pseudogap-quasiparticle features having primarily As 4$p$ character and spin
density wave transition induced band folding in the electronic structure. A
weakly dispersing feature of dominant As 4$p$ character is discovered around 80
meV that becomes weaker in intensity below 20 K manifesting influence of
antiferromagnetic order on conduction electrons. These results provide an
evidence of a link between the pseudogap states and magnetism that could be
revealed employing high resolutions.
