Afristreptaxis vengoensis is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Streptaxidae.

(Original description) The shell is comparatively large, oval, and rimate.

It is thin, transparent and olivaceous, with a smooth and glossy surface in the front and less so on the back.

The next four whorls are covered with close, prominent, oblique transverse striae with spiral pitting in the interstices.

Except immediately below the suture on the back of the shell, the sculpture becomes very faint on the body whorl, which is almost smooth, especially in front.
