Description
Original diagnosis after Engelbrecht, Mörs, Reguero & Kriwet, 2017 [25864]: Species of Abdounia differing from all other species of this genus by the following combination of characters: principal cusp blade-shaped; labial and lingual crown faces smooth; one pair of low and broad lateral cusplets in anterior teeth; in upper anterior teeth, no lateral cusplets present; in upper lateral teeth, mesial cusplet very reduced; distal cusplet broad and rather low; mesial cusplet reduced in lower lateral teeth; one or two distal cusplets; lingual protuberance well developed in upper teeth and less developed in lower teeth; and low labial root face.
