Diagnosis.

Scrapter peringueyi is morphologically very similar to S. heterodoxus . ♂: the male of S. peringueyi differs from that of S. heterodoxus in the shape of the projecting apical portion of the hind tibia, which is parallel-sided (tapering in S. heterodoxus ) (Figs 1E , 4E , 5A , 5B ). It further differs from S. heterodoxus in the surface sculpturing of the basal zone of the propodeum, which is substrigulate in S. peringueyi and rugulose in S. heterodoxus (Figs 1D , 3D , 5C , 5D ). The integument on the mesoscutum is shagreened between the punctation, whereas it is polished in S. heterodoxus .

♀: the female of S. peringueyi differs from S. heterodoxus in the same characters as the male, except for the shape of the hind tibia. The surface sculpturing of the basal zone of the propodeum is substrigulate, whereas it is rugulose in S. heterodoxus (Figs 2D , 3D , 5E , 5F ). The integument between the punctation on the mesoscutum is shagreened in S. peringueyi and it is polished in S. heterodoxus .
