But it differs in length of inner labial sensilla (5 µm vs. 12-15 µm), length of cephalic sensilla (35.7 µm vs 22.0 µm), mandible height/width (2.5 vs 1.2), and spicule length in cloacal body diameter (two different 1.7 and 0.8 vs 1.3).</p> <p>E. mus has similar “b” and “c” de Man’s ratios, gubernaculum and tail length in cloacal body diameter. But it differs in total body length (4700 vs 2540), inner labial, outer labial and cephalic sensilla length (17 vs 5 µm; 105 vs 50 µm; 55 vs 35.7 µm), mandible H/W (1.2 vs 2.5), and onchia length (27 vs 8 µm).</p> <p>E. paralitoralis has similar “b” and “c” de Man’s ratios, cephalic sensilla and tail length. But it differs in total length (1670 vs 2540 um), in inner labial and outer labial sensilla length (10–12 vs 5 µm; 62–66 vs 50.7), in cephalic capsule H/W (0.7 vs 0.3), and in mandible H/W (5.8 vs 2.5).</p> </div>	http://treatment.plazi.org/id/1C28879BFFF7352AB1ED7035FCB6FC6E	Public Domain	No known copyright restrictions apply.
