Key to the apterous viviparous females of the genus Cryptomyzus Oestlund, 1922

( Cryptomyzus elshotze Bhattacharya et Dey, 2001 and Cryptomyzus michaelseni (Schouteden, 1904) are not included in the key. The first species is described from fundatrix, the second species is described from the larva of the last instar).
