Group 3: Ammoecius 1 (4) Apical margin of clypeus with four sharp denticles. 2 (3) Pronotum strongly, densely punctate. Elytral striae deeply furrowed, intervals highly convex. 5 mm. - RSA (Cape Province) armaticeps Péringuey, 1901 3 (2) Pronotum finely punctate, elytral striae weakly incised, intervals nearly flat. 4-5 mm. RSA (Transvaal) dentinus Péringuey, 1901 4 (1) Both sides of clypeal emargination dentate or rounded. 5 (10) Intervals of elytra carinated, carinae on disc rarely somewhat indistinct. 6 (7) Each interval with three fine carinae, middle carina a little more raised than lateral ones, from striae only fifth and seventh reaching apex. Apex of clypeus deeply emarginate, both sides obtusely angulated. 5-5.5 mm. - RSA (Transvaal), (= carinulatus Péringuey, 1901) tri carinulatus Schmidt, 1901 7 (6) Intervals of elytra only with one carina. 8 (9) Genae not produced beyond eyes. From elytral striae fourth, fifth and eigth not reaching apex. Emargination of clypeus narrow, both sides obtusely angulated. 4-5 mm. - RSA (Cape Province) mimus Péringuey, 1901 9 (8) Genae strongly produced. From striae also seventh not reaching apex. Striae rather deeply furrowed, intervals roof-shaped. 5-6 mm. - RSA (Cape Province) spectabilis Péringuey, 1901 10 (5) Intervals of elytra more or less convex, not or carinated at most only on apex. 11 (12) Elytra with double rows of punctures (20 rows).
