Preprint typeset using LATEX style emulateapj v. 5/2/11 THE INFLUENCE OF RED SPIRAL GALAXIES ON THE SHAPE OF THE LOCAL K-BAND LUMINOSITY FUNCTION

We have determined K-band luminosity functions for 13,325 local Universe galaxies as a function of mor-phology and color (for Ktot ≤ 10.75). Our sample is drawn from the 2MASS Extended Source Catalog, with all sample galaxies having measured morphologies and distances (including 4,219 archival redshift- independent distances). The luminosity function for our total sample is in good agreement with previous works, but is rela-tively smooth at faint magnitudes (due to bulk flow distance corrections). We investigated the differences due to morphological and color-selection using 5,417 sample galaxies with NASA Sloan Atlas optical colors and find that red spirals comprise 20 to 50 % of all spirals with-25 ≤MK <-20. Fainter than MK =-24, red spirals are as common as early-types, explaining the different faint end slopes (α =-0.87 and-1.00 for red and early-types, respectively). While we find red spirals comprise more than 50 % of all MK <-25 spiral galaxies, they do not dominate the bright end of the overall red galaxy luminosity function, which is dominated by early-type galaxies. The brightest red spirals have ongoing star formation and those without are frequently misclassified as early-types. The faintest ones have an appearance and Sersic indices consistent with faded disks, rather than true bulge dominated galaxies
