The mean length of body lice (f 4.4 mm; m 3.8mm) was greater than that of head lice (f 3.5 mm; m 2.9 mm), but the best discriminate was the length of the tibia of the middle leg (f 425/296 mm; m 421/291 mm). No intermediate specimens were found in these double infestations, although intermediates can be produced experimentally by cross-mating. Since populations of head lice and body lice remain distinct it is concluded that they represent two distinct species, Pediculus capitis De Geer and P. humanus Linneaus.}, keywords = {Pediculus; clinical ; Ethiopia }, URL = {http://www.phthiraptera.org/Publications/1064.pdf}, author = {Busvine, James R.} }
