Species within the genus Eurema range from Asia, Africa, Australia, and Oceania, to the Americas. 
At least 71 species are currently known. 
The main differences between the species are:
a) the number of spots in the underside forewing cell, combined with
b) the shape of the upperside forewing black markings and
c) the shape of the apical area markings on the forewing underside. 

This is the subspecies Eurema salome jamapa which occurs in Mexico and south to Panama, and, sometimes, in Texas.

Andrew Neild, author of The Butterflies of Venezuela and a recognized authority on Neotropical butterflies, helped me identifying this species.
