According to Bates (1880): “It is difficult by description to make clear the differences between this species and A. binotatus , the colour and markings being very similar. The two, however, are very distinct. A. leucostigma is a decidedly narrower insect and is covered with coarser pubescence; the elytra are more gradually attenuated posteriorly, and the seriated punctures are more oblong.” However, at least two differences (sculpturing and pubescence) pointed out by Bates (1880), to separate A. leucostigma ( Fig. 1 ) from A. binotatus ( Fig. 3 ), are intraspecifically highly variable. Furthermore, comparison of the pubescence in photographs of the holotypes ( Fig. 1 , and 3 respectively), does not indicate any visible differences. This can also be said for their body shape. Accordingly, we consider A. leucostigma to be a junior synonym of A. binotatus .

Lingafelter et al. (2014) reported the existence of a specimen in the collection of USNM with a primary type label of Adetus venezuelensis and commented: “ Adetus venezuelensis Breuning 1942 . The holotype is deposited in the Muséum national d’Histoire naturelle, Paris, France.” Examination of photograph of that species ( Fig. 6 ) indicates it is a specimen of A. modestus Melzer, 1934 . Gérard L. Tavakilian (personal communication) said that the holotype of A. venezuelensis ( Fig. 2 ) really is in MNHN. We confirm that the synonymy between A. leucostigma and A. venezuelensis , established by Martins and Galileo (2003), is correct.
