1 Body glabrous or nearly so, more or less smooth. Base of aedeagus forms a closed bulb, basal hiatus shifted toward inner side. Larger species, 18–55 mm ................................................................ Tefflus Leach, 1819

- Body densely covered by straight setae, dorsum strongly punctured. Base of aedeagus opens between two weakly lamellate lobes, basal hiatus shifted toward dorsal margin. Smaller species, 8–30 mm ....................................... 2

2 Paraglossae surpassing glossa, ligula shorter, more slender; elytra black, without metallic lustre, unicolorous or each with one or more yellowish-red maculae........................................................................... 3

- Paraglossae not surpassing glossa, ligula longer. Unicolorous, small to medium-size species, mostly with metallic lustre, with- out any elytral maculae. Length 8–13.5 mm ................................................................. 8

3 Protarsi equal in both sexes.............................................................................. 4

- Protarsi in males differ from those in females.............................................................. 6

4 Mental process narrow, quite elongated. Pronotum longer than wide, hexagonal. Elytra strongly convex, each elytron with at least five yellowish or brick-colored pustules............................................. Psecadius Alluaud, 1911

- Mental process wide and truncate. Pronotum wider, differently shaped............................................ 5

5 Penultimate protarsomere beleved as the other protarsomeres............................ Craspedophorus Hope, 1838

- Bevel of penultimate protarsomere exceeds half of protarsomere length......................... Dischissus Bates, 1873

6 Protarsi in males slightly wider than in females, all tarsomeres without ventral brushes of setae....................................................................................................... Microcosmodes Strand, 1936

- Protarsi in males markedly wider than in females, some tarsomeres with ventral brushes of setae...................... 7

7 Second to fourth male protarsomeres very dilated, with ventral brushes of setae. Labrum excavated anteriorly, antennae shorter
