Type species.

Anthaxia flavimana Gory, 1841 (subsequent designation: Chamberlin, 1926).

According to Bellamy (2008), the genus Agrilaxia comprises 88 species. After removing of 5 species from Agrilaxia to Bilyaxia (see below) and after transferring of 5 species into the subgenus Costiptera subgen. n., 78 species remain in the subgenus Agrilaxia s. str. Quite naturally the subgenus will have to be split into several (or many) species-groups since several very different morphotypes (e.g. Figs 6 , 19 - 25 ) can be found within the subgenus - some of them have been suggested by Bílý & Brûlé (in press).

Note.

The very special morphological character of the subgenus Agrilaxia is the shape of the prosternum ( Figs 29 , 34a-34f ) which is normally flat or slightly convex. In the most species the prosternum is more or less transversely grooved just behind the anterior margin. The “grooving” of the anterior portion of prosternal plate and the relative elevation of the anterior margin of the prosternum which, in the extreme case, forms a sharp, transverse, rolled up ledge which is sometimes transformed into a peg-like, medial spine ( Figs 29 , 34f ).
