Start of the anterior dorsal spine of prefemur in males and females of Lithobius crassipesoides sp. n. (Spain) and L. crassipes (Germany and France). The DaP spine has been recorded on each leg of each specimen in French material: this explains the 0.5 graduation in this case (DaP being sometimes present on one side only).
