In the present paper we focus on the problem of the existence of strangepseudohyperbolic attractors for three-dimensional diffeomorphisms. Suchattractors are genuine strange attractors in that sense that each orbit in theattractor has a positive maximal Lyapunov exponents and this property isrobust, i.e. it holds for all close systems. We restrict attention to the studyof pseudohyperbolic attractors that contain only one fixed point. Then we showthat three-dimensional maps may have only 5 different types of such attractors,which we call the discrete Lorenz, figure-8, double-figure-8, super-figure-8,and super-Lorenz attractors. We find the first four types of attractors inthree-dimensional generalized H\'enon maps of form $\bar x = y, \; \bar y = z,\; \bar z = Bx + Az + Cy + g(y,z)$, where $A,B$ and $C$ are parameters ($B$ isthe Jacobian) and $g(0,0) = g^\prime(0,0) =0$.
