Chartergus metanotalis Richards, 1978 , Soc. Wasps Am.: 132 (key), 135, fig. 70, female, male—“ BRAZIL: MT, base camp, 12°50’S, 51°47’W ” (holotype female Rio de Janeiro); also from elsewhere in Mato Grosso, Goiás, Acre, Pará; and Ecuador.—Almeida and Castro, 1991, Acta Biol. Par., Curitiba 20: 43 (note on type material).— Sarmiento , 1994, Rev. Biol. Trop. 42 (1/2): 359 ( Colombia : Amazonas ; list).— Garcete-Barrett , 1999, Avispas Soc. Parag.: 30, fig.

Diagnosis. Clypeus wider than long, more transverse; clypeus touching the eyes for an extension equal than width of antennal socket; midlength gena equal to wider than eye; genal margin usually scarcely sinuate below middle, ventrally bending upwards and running in an almost straight line towards mandibles; humeri pronounced; pronotum with apical whitish yellow band, usually incomplete and stronger in the middle; pronotal keel with a whitish yellow band; without pronotal fovea; scrobal furrow with more or less regular carinae metanotum compressed; central tubercle of metanotum stronger; metanotum nearly always entirely black or with small yellow spots on the sides; first metasomal segment wider than long; second metasomal segment as long as wide. Chartergus metanotalis is structurally very close to C. artifex but on the average a little smaller, the clypeus and propodeum are usually more coarsely sculptured; and it differs from C. globiventris in the much stronger metanotal tubercle.
