  We study a class of four-dimensional N=1 superconformal field theories
obtained by wrapping M5-branes on a Riemann surface with punctures. We identify
UV descriptions of four-dimensional SCFTs corresponding to curves with a class
of punctures. The quiver tails appearing in these UV descriptions differ
significantly from their N=2 counterpart. We find a new type of object that we
call the `Fan'. We show how to construct new N=1 superconformal theories using
the Fan. Various dual descriptions for these SCFTs can be identified with
different colored pair-of-pants decompositions. For example, we find an N=1
analog of Argyres-Seiberg duality for the SU(N) SQCD with 2N flavors. We also
compute anomaly coefficients and superconformal indices for these theories and
show that they are invariant under dualities.
