Type species: Dipavali petri ( Russell, 1964) , late Thanetian, Cernaysian ELMA, Cernay, Berru.
Emended diagnosis: Louisinidae with cheek teeth with bulbous cusps. P 3 with low crestiform protocone. P 4 as long as wide, with paracone with convex mesial slope, small to medium-sized metacone, and small protocone. P 4 postprotocrista short, mesiodistally orientated (shared with Gigarton ). Lower premolar trigonids with concave distal slope. P 1 two-rooted. P 3 with low unicuspid talonid basin. P 4 with: inflated trigonid with metaconid much smaller than protoconid (shared with Gigarton ); gently sloping paracristid with virtually no paraconid (shared with Gigarton ); small talonid basin with hypoconid and entoconid. M 1–2 with: distal cingulum dipping basally

in middle (shared with Gigarton ); little or no postflexus; paracone taller than metacone; crest linking similar-sized protocone and hypocone; postprotocrista broken in most individuals; mesially pointed parastyle (shared with Berrulestes and Gigarton ); buccally concave centrocrista (shared with Gigarton ). M 1 essentially square in outline. M 2 trapeziform to trapezoidal, tapering distally. M 3 with metacone in median position. M 1–2 with: cristid obliqua with steep main slope (shared with Gigarton ); paraconid small, low, and crestiform; distally concave postentocristid, in occlusal view; entoconid subequal to metaconid; buccally situated hypoconulid. Entoconulid strong on M 1, weak to absent on M 2. Posterior mental foramen below distal half of P 4.
