There is a marked color variation with a geographical basis in 

 /. longulus. Western populations, particularly in and around Los 

 Angeles Co., Calif., are colored like I. oregonensis with a black or 

 nearlj^ black body and reddish-brown appendages. Farther east in 

 Arizona and New Mexico, the coloration is more like that of lanceatus 

 and beameri with body and appendage reddish brown. Few specimens 

 have been seen from the intervening area of southeast California and 

 we don't know if a cline of color characters exists. Genitaha and other 

 structural characters are quite constant, although a more detailed 

 analysis might reveal differences in some structures as the overall 

 size and shape of the pronotum.
