Mature larva of Mycetaea subterránea is re-described based on modern research techniques including SEM. Apart from the very inaccurate and little informative description of Agaricophilus reflexus larva by Mamaev (1977), the present paper contains detailed and richly illustrated description of the second known larva of the family Mycetaeidae. The phylogenetic placement of Mycetaeidae within Coccinelloidea is discussed, based on larval and adult characters.
