We studied the electronic structure of the Kondo lattice system Ce_{2}Co_{0.8}Si_{3.2} by angle-resolved photoemission spectroscopy. The spectra obtained below the coherence temperature consist of a Kondo resonance, its spin-orbit partner, and a number of dispersing bands. The quasiparticle weight related to the Kondo peak depends strongly on Fermi vectors associated with bulk bands. This indicates a highly anisotropic hybridization between conduction-band and 4f electrons—V_{cf} in Ce_{2}Co_{0.8}Si_{3.2}.
