TITLE: What are the maximal subgroups of GSp(2g,l)?
QUESTION [7 upvotes]: Is there a nice description of the maximal subgroups of $GSp_{2g}(\mathbb{F}_l)$? 
When $g = 1$ this is $GL_2(\mathbb{F}_l)$, and Serre (in his 72 Inventiones paper) classifies its maximal subgroups (Borel, Normalizer of Cartans, and a few exceptional subgroups). I expect a classification for general g to be longer, but maybe its managable when g = 2?

The Experimental Mathematics paper of Dieulefait for g=2 uses this. He quotes Mitchell from 1914.

Kleidman and Liebeck is on Google Books. There is also a brief survey of it.
