Ammatomus is a genus of Old World wasps whose biology is poorly known though at least one species may prey on leafhoppers of the family Fulgoridae (Bohart & Menke 1976).

Characters (from Bohart & Menke 1976): Medium-sized wasps: eyes large, inner margins converging strongly below; mandible with an inner subtooth; labrum usually visible; antennae of sexes similar in shape, club-like, last four articles in male not specially modified; median line on frons distinctly impressed; pronotal collar thin and closely appressed to scutum; female foretarsal rake weak, with more than two setae in basitarsal comb before apex; female foreleg arolium larger than other arolia: female forefemur often sharply carinate beneath; posterolateral oblique scutal carina present but faint or merely an angle in the margin; prescutellar sulcus simple; episternal-scrobal sulcus usually evanescent but curving around hypoepimeron when well impressed; omaulus, sternaulus and acetabular carina absent; metapleuron greatly narrowed below; forewing with media diverging before cu-a, stigma small, veinlet of submarginal cell II between recurrents short; jugal lobe larger than tegula, hindwing media diverging well before cu-a; midtibia with two apical spurs; hindtarsus nearly twice as long as midtarsus; propodeal enclosure convex, largely dorsal; no spiracular groove; abdomen not pedunculate or somewhat so; male with seven terga normally visible; sterna without fimbriae, sternum VIII sword-shaped with a small apical emargination; male genitalia with digitus of volsella undifferentiated; female pygidial plate densely setose.
