if you look from the top down, the females will be thicker around the anal than the males

Also the pectoral fins are broader in females, as well as females can be larger and fatter in general.

Sexing Corys is not always a simple case of the bigger fatter female ams slim smaller male, although generally this is the case, with the perfect example shown in inchworm's image of C. panda. Sometimes it is far more difficult and there is very little difference. In cases where you cannot tell by the body shape alone look at the ventral fins, this is where if there is going to be any difference at all it will be here. This can clearly be seen in this picture of C. nanus

The shape of the ventral fins of a female when spread, will be well rounded and fan shaped, in the male the ventral fins are more elongated and slightly pointed, especially in the second and third rays.

There are also a number of species that are quite obliging and the sexes have different colour patterns, sometimes though this can be so different that you would be excused for thinking that you were looking at two separate species. C. undulatus is a classic case in point.
