Genus Amphelasma Barber, 1947

Amphelasma Barber, 1947a: 158 (type species Galeruca cava Say, 1835 , by original designation).

Remarks

This genus currently contains only eleven described species, distributed from the United States to northern South America. However, some species currently placed in other genera may properly belong here. On the other hand, A. nigrolineata (Jacoby, 1878) , a species from Mexico and Central America, might more properly belong in Diabrotica Chevrolat, 1836 . See Figs 73 and 181 for illustrations of Amphelasma .
