[Drosophila] adult leg nervous system

[Julia.Luedke At physzool.bio.uni-giessen.de]

Dear Drosophila community!
I want to work with the adult nervous system, especially in the leg. I 
am interested in the afferent as well as the efferent part and i already 
found the line C161 (Smith and Shepherd 1996) that exclusively marks 
the sensory neurons. 
Now i would like to know if there are lines, that express Gal4 especially 
in Motorneurons or even exclusively in Motorneurons that target the 
adult leg?
Can anybody help with a hint to literature or the best ... a stock 
number?
Thank you in advance for any help,
Julia
