Turbinicarpus pseudopectinatus grows solitary with bluish green, depressed spherical bodies and has a fleshy taproot.

The flowers are either white with a reddish or magenta central stripe, or rarely deep pink.

[3] It is endemic to Coahuila, Nuevo León, San Luis Potosí, and Tamaulipas states in northeastern Mexico.

[4] The specific epithet pseudopectinatus is derived from the Greek word pseudo for 'false' and the similarity to the species Echinocereus pectinatus.

Charles Edward Glass and Robert Alan Foster placed the species in the genus Turbinicarpus in 1977.
