Aegista congener is a species of air-breathing land snails, a terrestrial pulmonate gastropod in the family Camaenidae.
The diameter of the shell attains 12 mm, its height 7 mm.
The shell of this species deviates from Aegista mitanensis <small>(Godwin-Austen, 1889)</small>, notably in its broader, less elevated shape, accompanied by a smoother, less pronounced angle at the periphery, and a significantly wider umbilicus.
This species occurs in Assam, India.
